6 Claims. (Cl. 53-13) This invention relates to the application of a covering material to a hollow package and more particularly to a method and apparatus for mutually manipulating a paper-like covering material and package during a wrapping operation.

The present invention is particularly useful for the application of a protective covering member having a restricted exibility of the nature of a paper sleeve to a hollow package of artificial filaments, such as a cake of rayon obtained by collection in a spinning pot.

Although various devices have been developed to mechanically apply flexible knitted or woven sleeves to rayon cakes (see Patents Nos. 2,418,657 and 2,436,481), it has not been possible to do the same with paper sleeves having a limited flexibility. The devices of the patents could not be adapted for such use as it was determined that in manipulating the paper sleeves in this manner they were torn and otherwise rendered unsuitable.

Therefore, normally the procedure of covering the package with paper, hereinafter designated as socking, was performed by hand. This procedure of manually socking the cakes not only consumed considerable time but often resulted in irregular filaments due to the prolonged handling.

'l`his invention therefore provides for the socking of cakes with paper in less time than was heretofore required while also reducing one factor tending to cause irregularity in filaments.

It is an object of this invention to provide a simplified form of apparatus for the application of a protective covering material having a restricted flexibility to a hollow package of artificial filaments such as a freshly formed cake of rayon.

Other objects and advantages of this invention will become apparent from the following detailed description when considered in conjunction with the accompanying drawings, wherein:

Figure 1 shows a front view in elevation partly in section of the apparatus of this invention when in a fully expanded position, the package being removed for purposes of better illustration;

Figure 2 is a fragmentary View of a portion of the apparatus of Figure l showing the relationship of parts when in the normal position of repose;

Figure 3 is a plan view of the apparatus of Figure l;

Figure 4 is a'fragmentary side elevation view at right angles to the View point of the apparatus of Figure l; and

Figures 5, 6 and 7 are detailed sectional views showing the cycle of operation of socking a hollow package.

Referring now to the drawings and more particularly to Figures l to 4, the socking apparatus is supported on a frame generally indicated at 10 which includes four legs 11, the upper ends of which are fixed to a ring 12. Connected to the frame by being secured to braces are crossbars 13 and 14. Cross-bars 13 and 14 serve as support members for the upper and lower ends, respectively, of shaft l and maintain shaft 15 in a vertical position. Cross-bar 13 has a hole therethrough forming a bearing .rice

therein through which shaft 15 may pass when the apparatus is being assembled or disassembled. When the apparatus is assembled, however, the upper end of shaft 15 rests within the bearing.` Cross-bar 14, against which shaft 1S rests, has a collar 16 attached thereto within which the lower end of shaft 15 is removably mounted. Surrounding the lower portion of shaft 15 is a slidable sleeve 17 which normally rests on collar 16 when the apparatus is in a position of repose as shown in Figure 2.

Extending between two of the legs 11 with each of its ends secured to one of the legs is a shaft 18 about which is pivoted a pedal lever 19.V Fixed to one end of the pedal lever is a pedal 20. The other end of the pedal lever is forked at 21 to it around collar 16 when the apparatus is in a position of repose as shown in Figure 2 and raise the slidable sleeve 17 upwardly along shaft 15 when the foot pedal is depressed as shown in Figure 1. Above the slidable sleeve 17 and fixed to the shaft 15 by means of a set screw is a collar 22 which restricts the upward movement of the sleeve 17 along the shaft 15.

Surrounding the upper portion of the shaft 15 is another slidable sleeve 23. Also surrounding the shaft 15 and fixed thereto on each side of the slidable sleeve 23 are collars 24 and 25. Collars 24 and 25 restrict the longitudinal movement of sleeve 23 along the shaft 15. The collars 16, 22, 24 and 25 are so positioned on shaft 15 as to allow for less longitudinal movement of sleeve 23than sleeve 17. The reason for this lesser movement will be discussed more fully hereinafter. Surrounding shaft 15 and in contact with sleeve 23 and collar 24 is interposed spring 26. Spring 26 is compressed by the combined weights of the slidable sleeves 17 and 23 and their attaching elements when the apparatus is in a position of repose as shown in Figure 2, but upon the depression of the foot pedal which releases the spring 26 of substantially all weight except that of the slidableV and pivotally connected to the ends of levers 29. EX

tending substantially downward from slidable sleeve 23 when the apparatus is in a position of repose and having one end of each pivotally connected thereto are a plurality of radial links 30. Similarly, the other end of each of the radial links 30 is forked and pivotally connected to an intermediate portion of one end of the levers 29.

Referring now to ring 12 there are two platforms 31 mounted thereon and located diametrically across from each other. Mounted on each of the platforms 31 is a support 32 pivotally mounted at an intermediate portion of the half ring bars 33. Secured to one end of each of the bars 33 is a half ring 34 upon which the package is initially supported. The other end of each of the bars 33 pivotally mounts one end of a slotted bifurcated lever 35. The slotted and bifurcated portions of levers 35 tilt over two of the levers 29. These two levers 29 carry pins 36 therethrough which ride within the slots so that upon the vertical movement of lever 29 the pins 36 willride within the slots to their ends and then force levers 35 upwardly to pivot the half rings 34 to an open position.

Also mounted on each of the platforms 31 is a support Referring now moreV particularly to lever 29 theupper ends of which carry vertical fingers 4t) which move Vfrom a position beneath the filament package to a position'sur- Y rounding the package when the foot pedal isdepressed..

The upper ends of some of the levers 29 also .carry ears;

.41A thereon upon which. fthe completely socked package may rest after the Vfingers 4i) have been completely eX-'V panded. v Y i Y With lthe parts constructedand arranged as hereinbefore described the operations as shown by Figures 5- kbriefly stated is as follows: Y

With the hait rings 34 in the closed position such as.

that shown in Figure 5 a package of artificial filaments is placed lupon the half rings 34. A paper sleeveY 42 of ra length severaltimes the yheight of the cake is then 'placed over the outsidevof the package and the clamp 38l is closed'tohold thepaper sleeve against the package. The paper Sleeve extendingabove theV package is then collapsed and passed down through the center of the package until it extendsbelow the package. The portion of the Vpaper sleeve extending. below the package is then flared out and placed over the fingers .40 as shown by dashed Y lines in Figure 5. While supporting the cake with both Vhands the operatorpresses the foot pedal. The depressing of the foot pedal raises the forked end 21 of pedal lever l' and thereby the'sleeve 17. When the sleeve 17 moves upwardly along the shaft 15 and with it the lever 29 they no longer act to compress the spring 26. With the pressure releasedon the spring 26 the spring 26 eX- pands to force the sleeve 23 upwardly along the shaft until it reaches the collar 25 whereupon its upward movement is stopped. The sleeve 23. because of'the difference in stroke length of sleeves 23 and 17 reaches the collar 25 before the sleeve l7-reaches the collar 22. Inasmuch as Vthe sleeve 17 is still continuing to move in an upward kdirection the links 3% pivoting on the sleeve 23 move to a more horizontal position and thus increase the diameter Y of the horizontal area enclosed by the fingers 40..

Simultaneously with the upward movement of the lever 29 the pins 36 slide along the slots until they reach the'end of the slots whereupon a further upward movement of levers 29 forces the half rings 34 and thus the clamp 38 to spread apart thus removing all support'from 1.
