2 Claims. (Cl. 118-44) This invention -relates -to an ink or pigment tipping and/or inl-ay attachment for embossing calenders to impart ink and coloring pigment to the embossed material such as cloth, fabric or plastic sheets.

-It is .the principal object of the present invention to terial embossing calender so that the coloring of the embossed cloth fabric or plastic is effected at the time of the embossing whereby tipping or inlaying of the embossed material will be eiected while still upon the actual embossing roll, and in true ali-gnment thereupon with a firm, even and level inking plane available because the paper backing roll pattern is still backed up and is still pressed into the raised portion of the embossed material in contrast Ito .the spongey, uneven and bumpy inking plane which must be used when tipping is done after the material has been removed from the paper lbacking roll.

Itis another object of the invention Ito convert a material embossing calender into a combined embossing calender and tipping or inlaying machine by a tipping r inlaying attachment adapted to be secured between the sides of the standard cloth embossing calender machine.

It is another object of the invention to provide an ink tipping and/or inlay attachment for material embossing machines that is adapted -to be located at different elevations on the embossing machine frame to engage'either the large embossing roller or the cooperating indented press Iroller whereby to provide inking or coloring on either the projected embossings of the material from the paper roll or upon the female die roll to effect inlay coloring in the unembossed portions of the material or by a combination with the use of two tipping attachments to effect the coloring of the embossed portions and the unembossed portions of the cloth together.

It is another object of the invention to provide a tipping and/ or inlay attachment for material embossing machines wherein two such attachments are provided on the machine at different elevations wherein their ink or coloring rollers engaging with the embossed material are'relieved to skip or leave certain of the embossed portions uninked while inking other of the embossed portions and wherein ythe uninked embossed portions leaving the first tipping attachment will be inked by the second tipping attachment with another color while skipping the already inked or colored embossed portions inked by the first tipping attachment whereby to provide a multi-colored tipped embossed cloth. l

It is another object ofthe invention to provide a tipping and/or inlay yattachment for material embossing machines employing a series of ink pick up rolls, the rst dipping into an ink tray and transferring to a second roll and this second roll finally transferring the ink to the work engaging -roll wherein an adjustment of each of the rolls can be effected relative to each other by adjusting screws and the inking rolls are driven by gearing connecting the rolls together, the intermediate `roll being power driven provide a tipping or i-nlaying attachment for a sheet ma---z with a variable speed drive mechanism whereby the surface speed of the work engaging roll Acan be regulated according Ito .the surface speed of travel of the embossed cloth.

lIt is another object of the invention to provide a tipping and/or inlay attachment for material embossing machines which has independent screws for individually adjusting the rollers and the attachment is so mounted -that it may be quickly adjusted as a unit and wherein once the adjustment of the rollers is made relative to each other they need not be altered in order to remove the rollers from their work engaging position -by a simple pulling of a lever wherein adjustment can be effected between the operating lever and the frame carrying the rollers in order to quickly effect the proper engaging contact of the work engaging roll with the embossed portions of the material so as to avoid blistering of the synthetic rubber on the work engaging roll should the entire machine be stopped and also to avoid loss of improperly tipped or inlayed cloth due to delay in readjustment of the work engaging roll.

Other objects of the invention are -to provide a tipping attachment sheet for material embossing machines which is of simple construction, inexpensive to manufacture, has a minimum number of parts, easy lto install upon the embossing machine and adjust relative thereto, compact and consumes little space, durable, of long life, elective in use and eicient in opera-tion.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing in which:

Fig. 4 is a vertical sectional view taken through one end of the tipping attachment frame as viewed generally on line 4-4 of Fig. 3; Fig. 5 is a fragmentary sectional view of a slightly modified form of the invention with illustration being made of the inking roller of the attachment being relieved to permit the escape of certain of the embossed portions of the material as when a multiple color tipping operation is effected upon the material by two or more tipping attachments one mounted above the other or even in a circular arrangement around the embossing roll so as to accommodate a greater number of such attachments.

Fig. 6 is a fragmentary perspective View of one side of the embossing machine wherein two attachments ar Fig. 7 is an enlarged sectional view of the adjustable gear of the one tipping attachment as viewed generally on line 7--7 of Fig. 6; and Fig. 8 is a fragmentary perspective view of one end machine.

the lever for moving the inking rollers into and out of their working positions as a unit and without having to effect the adjustment of the individual rollers.

Referring now particularly to Figs. l and 2,'there is shown a sheet .material embossingcalender indicated generally at and having side frame members '16 and 17 at the opposite sides of the calender and joined together by .appropriate tie bars 18 located at diterent stations along the length of the machine. Mounted on the -s'ide frames 16 `and 17 are respectively heavy bearing members 19 in which shaft -ends 2d and 21 ofa large diameter paper backing roll 22 are `journalled --to support the paper backing roll 22 'between the side frames 316 and -17of the This paper backing rol-l 22 is driven by Yappropriate'power gearing, not shown, to cause 'theA passage of 'clothor fabric 24 through `the-calender. This p aper roll..22:has a thick paper layer 25 against which aV steel engraved female .embossing press Vroll 26 is empressed to eect the formation of complementary male projections 27 upon the paper layer 24 which will'conform to indentations 28 Iinthe engraved embossing'or press roll 26,. The .paper'roll 22 mayalsobe formed with'a backing layer of synthetic rubber, plastic, synthetic cornpounds, nylon, fDacronj cotton, felt, wool .or wood.

The cloth material'Z-'i `in passi-ng between these rolls is tive side frame members by respective nuts 32 and eX- tending upwardly throughslots 31' inthe ends of :arms 29. A piston vrod 33 is connected to each arm 29 by a set collar 34 ,engaging with the upper end of thermember 29. and with a power cylinder device 35 anchored to a bottom bracket 36^by ya pin 37. As hydraulic or pneumatic pressure is supplied to thedevice 35, the arms 29 are Vbrought down and `the' Y embossing or press roll 26 is brought'into tightengagement with the cloth 24 'and paper `backing roll 25. l

On one end of the calender are brackets 38 that support a cloth supply roll 39 from ywhich cloth 24 is taken to be embossed. This cloth travels upwardly and forwardly over three small tension rolls dit, 41 and 42 before reachingthelarge vdiameter'paper backing roll 22.

lWith the .embossing or press roll 26 in place upon the paper roll.2'2, the `cloth-is .embossed as it is passed lbetween the rolls and continues to run over the paper backing roll 22 .andpast an ink or color tipping Vattachment 43 constructed according lto the present invention. From the paper backing roll 22 the cloth passes rearwardly over -a ing brackets 48 and .49 on the respective side frames 16 and`1'7 of the calender at 1the opposite end thereof from the .cloth supply roll v39'.

brkef's 45l) and 51a the opposite .ends thereof are respectively secured eccentric cams 55 and 56 lying respectively. within operating follower rings 57 and 58. A hand lever arm 59 is secured to one .end of .the shaft34 and when ings 52 and 53 and just inwardly of the supporting d used to rotate the shaft 5d, the follower rings 57 and 58? will be caused to move either forwardly or rearwardly.

Each follower ring 57 or 5S has an internally-threaded portion 60, Fig. 8, into which is threaded :a threaded shaftv 61 having threads cut in one direction and when adjusted is locked to the portion 69 by a lock nut 62. A turnil buckle sleeve 63 is secured to the opposite end of the shaft 61 and to a threaded shaft 64 having threads cut'- in the opposite direction of the threads of the shaft 61`l `50 and 51 are respectively yfixed to the angle section brackets 70 in back to back relationship and are secured therewith as a unit to theside vframe member 16 or 17.

Slidable along the angle ysection supporting bracket-- 70 is a depending braket 71 of Z-section-that has la horizontal portion 72 that is .welded to the bottom of the slide 65 and which rides over an inwardly extending f.

portion 73 of the angle section supporting bracket 70.

The inverted sudeway `channel guide 67 has spaced elongated slots 75 and 7,6, Fig. 3, into which extend respectively screws 77 and 78 that connect abottom side PQrfiQn 79 of an uri-Standing guide frame 80 with the slide V6,5 within the inverted channel guide 67 so that as the slide 65 is moved, the guide frame member 8l),y is,-

moved.

The guide frame 80 has a top side portion 81 and an; intermediate guide portion S2 lying between the bottom side portion 79 and the top side portion-81, Fig,` 3. The guide frame 80 is integrally Vclosed at one end and the other end is closed by vertically-extending lower and upper plates 83 and 8,4 through which there extendrespectively adjusting screws 485 ,andz86 that respectively have hand adjusting wheels 87 and 88 that are respectively'retained bypins 87 and 88.

Theadjusting screw is connected to a slide support y89 that has ya retaining sleeve 90 secured thereto by a spring ring 91 and Vsupports a bearing sleeve 92, Fig. 4. A roller lshaft 93 of intermediate rubber ink transfer roll '94 Y is journalled in theV bearing sleeve 92. By turning the adjusting screw 85, -slide `89 Vand one lendvof thefinkl transfer roll 94 is adjusted in the frame S0. A similar adjustment may be made at the opposite side of the attachment.

The adjusting screw 86 is connected to a slide sup.-

port 95 adjustable along guide portionsSl and V82 above the slide support 89 and which has a retaining sleeve96,

Figs. 3 and 4, secured by a spring ring 97 to theslide 9,5

and .thatsupports a bearing sleeve ,'98v in which is journalkled a ushaft r`99 of a top-delivery synthetic ,rubber v`or Plastic tipping roll .adapted to engage the raisedcr l embossed portions of the cloth as the embossed cloth moves past'the tipping attachment 43. `The inking roll 10.1)v engages with the intermediate transfer roll 194 .to refV c'eive or color pigment therefrom.

engraved ink pick-up -metal roll -102 that dips in a tray 103 to pick up the or colorpigment usedforythe f tipping of the embossed clothfFigs. 3 and .8. yThe trav 103 `is supported on ahorizontal portion 10.4 of the .de-

pending Z-.bracket 71 by a verticaladjustmentfscrew :105 'i turnable throughfa depending nut-106 ,-iixed V.to the bracket portion104 Yand journalled ina dependingboss :107 on j thebottom of the tray 103. They adjusting .screw `1,051has a handwheel knob 108 by which the screw i105V isfturned. The tray `contains the ink or pigment to be transferred to f v theiembossed portions of the cloth 24. With agiven i depth :of ink or-colloi pigment in the tray, vtheaqllillll i can Ibe;adjusted to press more or less againsttherubbe.'

elow the intermediate ink roll 94 is a knurled :.01` f transfer roll so as to impart more or less ink to it. A similar adjustment may be made at the opposite side of the attachment.

0n each end of the tray 103 is a bracket 109 that has an open vertical slot 110 therein for receiving a shaft end 111 in which the pick-up roll 102 is disposed, Fig. 3. Since the pick-up roll 102 is carried by the tray 103, it will be adjustedwith the tray toward and away from the intermediate transfer roll 94.

To eiect equal distribution of the ink or color pigment upon pick up roll 102, a wiper blade 113 engages the surface of the roll 102, Figs. 3 and 8. This wiper 113 is held between two retaining plates 114 and 115 and secured together by nut and bolt means 116. On the Z-bracket 71 there is fixed a pivot pin 118 that carries a depending pivot arm 119 that is adjusted by an adjusting screw 120 threaded through a lug portion 121 on the Z-bracket 71 and which has a hand turning knob 122. The top plate that holds the wiper blade 113 has a bearing portion 123 that extends over the pin 118 and is connected by pin 123' to arm 119 so that movement of the arm 119 will cause movement of the wiper 113 and change the point of engagement with the wiper upon the pick up roll 102.

As an alternative means for holding the wiper on the roll, there is provided a weight arrangement to be presently described. Mounted on frames 80 at the tops thereof are respectively upwardly and rearwardly inclined brackets 124 and 125, Figs. l and 2, and between these brackets 124 and 125 is xed a shaft 127 on which are journalled axially-spaced pulleys 128 and 129. Extending rearwardly from the wiper retaining plate 114 are spaced rearwardly-extending hook arms 130 and 131 to which there are respectively connected pulley cables 132 and 133 having respectively weights 134 and 135. These weights act upon the wiper blade 113 in such a manner as to hold the same tight against the ink pick up roll 102. For this action the pins 123' will have been removed, and the adjusting screw will have been disengaged from the pivot arm 119.

At times the wiper blade 113 is positioned on the bottom side of pick up roll 102 in the reverse manner of the showing in Fig. 3 and in order that the weights may be applied properly to maintain the wiper in this position, the spaced hooks 130, 131 are fastened to the retaining plate 114 in the reverse manner from that shown in Figs. 1 and 2, and the weights 134 and 135 are hung directly therefrom whereby the edge of the wiper element 113 will be held against the underside of the ink pick up roll 102. In this position of the blade, ink is not put into the pan but is poured between the blade and the knurled or engraved roll and is prevented from flowing rapidly out into the pan by means of a felt pad or dam cut out in a V-shape to t between the blade and the roll and held in place by a brass clamp with thumb screw fastening to the blade at each end thereof. Several of these dams can be clamped in position on the blade and different colored inks can be poured between them so as to give a multi-colored striped eect to the tipping or inlaying.

The inking rolls of the attachment are driven by a variable speed drive mechanism 137, Figs. l and 2, having an electric motor 138, a control handle 139 and a reduction gear mechanism 140 having a pulley 141 that is connected by a multi-piece belt 142 with a pulley 143 on the shaft 93 of the transfer roll 94. This shaft 93 has a driving gear 144 that is meshed with a gear 145 ixed to shaft 111 of the pick up roll 102, Fig. 2, and the gear 146 xed to shaft 99 of the rubber tipping roll 100. By turning the control lever 139 the speed of the tipping roll 100 will be altered so that the surface speed of the tipping roll 100 can be run opposed or in the same direction as, and synchronized with, or at a greater or less sped than the surface of the paper backing roll 24 having the embossing projections 27 as desired. By operating the hand wheels 87 and 88, the rolls 94 and 100 can be adjusted to different forward and rearward locations in order to properly have the tipping roll engage the projections 27 and the cloth running thereover. The ink pick up roll 102 is adjusted from underneath the attachment by the hand Wheel 108. Once the proper adjustment of the rolls has been made, the rolls can be moved into and out of the tipping position as a unit by the lever 59 without effecting their adjustment. It will thus be seen that the tipping attachment 43, as applied to the cloth calender as shown in Figs. l and 2, has its own independent driving mechanism. The tipping attachment, as set up in this manner, merely has to be adapted for the application of ink to the cloth. By pulling any one or al1 of the levers 59 of the tipping units, any one or all of the units can be disabled or dispensed'with. y

To provide upon the cloth 24 both the coloring of the projections and of a color inlay or ground, an inlay attachment of like construction to the attachment 43, Fig. l, is similarly connected between the side frames of the calender so that its surface engaging or tipping roll 151 will deposit ink or color pigment on the surface of the embossed press roll 26 and free of the recesses 28 so that this ink as the press roll 26 revolves is deposited by the press roll upon one side of the cloth 24. The tipping attachment 43 covers the embossed projections of the cloth with further ink which may be of different color. The variable speed drive mechanism 137 has a double pulley so that the inlay attachment 150 is driven by a pulley belt 152 extending to the attachment 150. If it is desired to have only the inlay coloring from the attachment 150, the tipping roll 100 of the attachment 43 can be withdrawn by merely pulling the lever 59. This can be eected at the will of the operator and the attachment 150 will be similarly provided with a lever 59 so that it can also be withdrawn thereby and selective operations of the attachments can be eiected.

To color the embossed portions of the cloth with two or more diierent colors, a pick up roll 100 of the attachment 43 is shown in Fig. 5 provided with recesses 155 so that certain of the embossed portions of the cloth escape tipping while other embossed portions will be tipped as indicated at 156. Another tipping attachment indicated generally at 157 has a tipping roll 158 similarly provided with recesses 159. These recesses 159 are arranged to permit the escape of the embossed projections tipped by the roll 100' which have been provided on the attachment 43 and tip the remaining embossed projections. In a similar manner two or more dilferent colors may be inlayed in the ground or unembossed portions of the cloth material likewise using a gearing arrangement as described in the next two paragraphs.

When the tipping or inlay attachment 43 and 157 are used in this manner to skip certain embossed projections of the cloth and to give different coloring to the skipped projections, a drive arrangement permitting the adjustment of the tipping roll of one attachment relative to the tipping roll of the other attachment is needed. The shaft end 20 of the paper roll 22 is provided with a large drive gear 160, Fig. 6. The tipping attachment 43 is provided with a small gear 161 on its shaft 93 of the transfer roll 94 which engages large gear 160 to be driven thereby. The belt from the variable speed drive mechanism 137 will have been disengaged and the operation of the tipping attachment 43 will now be wholly driven from the large gear 160. An adjustable gear 162 is provided on a shaft extension 163 of a transfer roll 94 of the attachment 157. This adjustable gear 1 62 is constructed as shown in Fig. 7 and comprises a sleeve 164 that is keyedV to the shaft 163 by means of a key fitting keyway 16S. The sleeve 164 is held against axial displacement on the shaft 163 by a set screw 166. A set collar 167 is fixed by a set screw 168 to the sleeve 164. Against this set collar 167 is rested a small gear 169 that meshes With the large gear of the paper roll.

Fixed to this small gear 169 by screws 171 is a supporti512: Plf 17,2- 'Plaie .17 ZEhasn-ftwo r spacedr-flpgs... l173 and,174Y l betweenwhich is; `jem'rlallecl a i wornrj-rgear., 115 thenbau be adjusted-.or turnediby-nsertingra wrench into awarenehsopening .1 76. t Thisvworm'. gearf175fmeshes @with awormwheel 177 Ithatiis keyed; byedeyi 17.8.10 asleeve 16,4. ,Srince the sleeve 164, is tif edtothe shaft;163,;a tui ingtoftheworm gear 175,wi1l .,eect, aishiftingfothe tip r g -.:roll100". of the ,tippingattachmentffsorthat its re- @55.68; 155'. canA be aligned, and i accuratelyt vregistered I,to groperly receive the` alrealytipped embossed projections ofthe cleth- 'Iflletipping ttwhmentsr can. accordingly :be outwardly moved 'as a ilnit :by the handf1ev.er,59 as above explained aridgtlie-ge,arsV v161 and 162.diseng aged =fromthe gearl. 111e tipping attachments, are similarly,constructed-throughout iicept for the diierences in thesdrivi'ngofr-rthe same and `,in ,t he. recesses vof; the ltippingrrolls Zas already -set forth.
