Definitions

  • a folding machine of the portable type which performs a final up or down plow type fold on documents such as sheets of paper and the like, which are held in register, folded, compressed, and delivered in folded condition.
  • a finished product that has one or more pockets thereon which can be used to hold other items.
  • a sheet of paper is scored up from and parallel to the bottom to form a flap.
  • a glue line is applied to one or more edges of the flap, which is folded up along the score line to contact the main sheet of paper and form a pocket.
  • it is desirable to provide a cover over the pocket in which instance the sheet is scored lengthwise to form a cover flap, which also may be provided with a pocket, and which cover flap is then folded over and onto the main sheet.
  • the grabbing or nipping action does not always exert uniform and perfectly straight forces on the leading edge of the sheet being accelerated. Indeed, there is a tendency for some of the individual flaps to be cocked or skewed from a desired position in which their leading edges are at right angles to the flow path. In the event of flaps cocking or skewing as the sheets leave the folding section, the subsequent grabbing action produces unsymmetrical flap orientation, and an unacceptable finished product. This problem is overcome, in the present invention.
  • None of the prior art apparatus discloses a folding machine which can fold a flap up, or fold a flap down, as required, and particularly where a pocket has already been formed on one or more parts of the sheet being processed.
  • This invention relates to a plow type folding machine for paper and the like, which receives a sheet of paper which may have one or more pockets, and has been scored lengthwise to form a cover flap, registers the sheet, and performs a plow type fold to fold the flap down or up to cover the pocket, compresses and then delivers the folded sheet for further processing.
  • the principal object of the invention is to provide a plow type folding machine, which registers a sheet of paper, which has been scored lengthwise, and folds a flap up or down along the score line, onto a main sheet, and in aligned relation.
  • a further object of the invention is to provide a folding machine of the character aforesaid, which is fast and accurate in its operation.
  • a further object of the invention is to provide a folding machine of the character aforesaid , which can be easily set up to provide an up fold, or a down fold of a flap onto the sheet of paper.
  • a further object of the invention is to provide a folding machine of the character aforesaid, which is simple to construct and maintain.
  • a further object of the invention is to provide a folding machine of the character aforesaid, which can fold a large variety of types, and configurations of sheets of paper and the like.

  • a guard 193 is provided, in the delivery section 15, of U-shape, open at the ends, and fastened to upper mounting plate 90 by bolts (not shown) in well known manner.
  • a transport or feeding table 195 is provided, shown in phantom, and which receives folded documents 12 from delivery section 15 for further processing as required.
  • the rod 170 is adjusted so as not to interfere with the downward rotation of cover flaps 11, as they come off plates 51 and 60, and rods 70, 75 are adjusted to appropriate positions to contact and guide flaps 11.
  • the motor 150 is actuated to drive roller 58 and belt 55.
  • Documents 12 are fed onto belts 41 from pocket fold machine 27 against guide plate 49, and under member 47, where the documents 12 are registered.
  • the belts 41 deliver the documents 12 to transfer plate 51 and onto belt 55, and extension plate 60.
  • As the documents 12 move onto and off plate 51 their main panels 12A are engaged by guide roller 61, and as the cover flaps 11 are no longer supported by the plate 60, they fall downwardly until they contact rods 70, 77, with the score lines 30 against the edge 173 of bed plate 57.
  • the flaps 11 are rotated downwardly by rods 70, 77, and are then upwardly and contacted by rod 172 until the flaps are under plate 57.
  • the documents 12 are also contacted by rollers 85, and by roller 171 on score lines 30, forcing the documents 12 against edge 173 of plate 57 and urging the flaps 11 upwardly while the rest of the document is carried along on belt 55.
  • the documents 12 are moved off belt 55, and into the delivery section 15 where they contact belt 160, and then belt 140 which carries them between the rollers 111 and 139, which compresses the main panel 12 and flaps 11 of documents 12, and delivers them onto a feeder table, such as table 195 for use as desired.
  • cover flaps 11 When it is desired to fold cover flaps 11 initially upwardly, guide and contact rod 170 is moved under extension plate 60 so that flaps 11 will be supported as the documents move off plate 60, and along belt 55.
  • the cover flaps engage rod 180, which rotates flaps 11 upwardly and between rods 180 and rod 185 onto belt 55, under roller 171, onto surface 86, onto panel 12A, and the documents 12 are moved off the belt 55 to delivery section 15, where they are engaged by belts 140 and 160, and further compressed between rollers 111 and 139.
  • the documents 12 Due to the divergent angles between the belts 140 and 160 at the entrance to the delivery section 15 from belt 55, the documents 12 are not immediately gripped, and are not compressed between rollers 111 and 139 until they are substantially off the belt 55, which results in substantially folding the entire length of the documents 12 along the crease lines 30, while registered and under pressure from rollers 171 and 85.
  • the cover flaps 11 are therefore maintained in alignment until the documents 12 contact the belts 140 and 160 at the location of the rollers 111 and 139, which further compresses the documents 12, and maintains the alignment of flaps 11 as the documents 12 pass therethrough and are delivered for further processing as desired.
