Definitions

  • This invention relates to apparatus for receiving and refolding in fan-fold arrangement a web of paper exiting from a computer printer. More specifically, this invention relates to a lightweight compact and economical apparatus which takes up little if any desk space for receiving and refolding the output of a computer printer. Still more specifically, this invention relates to an apparatus which is of economical constu- ction which will receive and which will refold the computer printout into the same fold pattern as had existed on the supply side of the printer.
  • Paper stacking systems are well-known and are utilized in a wide variety of applications.
  • a typical application is that in which fan-fold paper and other forms are fed into printers and the like for printing data typically exiting from a computer, the data being processed in a high speed fashion.
  • Paper on the supply side is normally withdrawn from the carton or box from which it is purchased, and p'assed through the printer where the printing takes place.
  • the paper is then fed in an incremental or in line-by-line fashion through an output slot in the printer in order to be stacked in a paper stacker or a basket.
  • the Patent to Muller illustrates a paper feed and refolding guide mechanism, including curved sheet metal plates which form a passageway through which the web of paper is fed.
  • the Ziegler et al patent (3,712,607) relates to guides and stacking mechanisms for continuous paper forms during their passage from a printing device over a guide and through a stacking mechanism to a collecting table.
  • the patent to Koning discloses a fan folded paper stacker which is used with printers in data processing systems. This patent, however, utilizes a forward and backward oscillating motion to insure the fold and additionally uses a chamber having reduced air pressure below the paper web.
  • the patent to Lettan (3,178,172) is directed to handling apparatus for folding material and includes a receiver for receiving zig-zag forms.
  • the paper refolding apparatus fits directly over the printer in such a way that additional desk space is not required. If desired, the printer can be raised and the supply side carton of paper can be placed below the printer so that even less space is required. Nevertheless, applicant has provided a simple L- - shaped member having a curved guide means suspended from a vertical back, which receives the output of the printer and takes it through a curved path and then directs it downwardly toward the base of the L-shaped member which forms the refolding surface. Additionally, according to this present invention, there is a proximal stop and guide means so that the integrity of the fold pattern of the web as it existed in the carton or on the stack of the supply side is maintained on the refolding surface. It is necessary only for the operator to manually manipulate the leading edge of the print-out of the paper web so as to assure that the integrity of the fold pattern be maintained on both sides of the printer.
  • Fig. 1 is a view in perspective illustrating the refolding apparatus of the present invention in place over a typical personal type of printer.
  • Figs 2-6 illustrate the process of feeding the web of paper from the supply side to the printer and threading it into the guide means of the refolding apparatus for refolding in the pattern which existed in the carton or box on the supply side.
  • Figs. 7-10 are diagramatic illustrations again illustrating the manual manipulation of the first fold issuing from the printer which is required to allow for subsequent automatic refolding of the paper web in the fold pattern as had existed on the.supply side.
  • Figs. 7-10 illustrate a variation of the proximal guide and stop means and the elimination of the swinging flap which was illustrated in Figs. 1-6.
  • a typical computer printer 1 is shown with the inlet web 2 feeding from the box B from the stack of fan-folded paper on the supply sides of the printer.
  • the folds as shown in Fig. 2 are designated by the letter F.
  • the paper normally is perforated along its side, and is driven by a drive sprocket shown as D in the printing mechanism 1 although it is of course within the scope of this invention to utilize paper without the sprocket drive perforations. If a drive sprocket is not used, the paper is driven by pressure rollers according to conventional practice
  • the paper refolding apparatus itself consists of an L-shaped refolding member '4 having a vertical back 5 with an inclined wall 6 and a base 7 which forms the refolding surface.
  • the base has a proximal ledge 8 and there is a proximal planar surface 9 which extends from the bottom of base 7 to the proximal ledge 8.
  • An inclined proximal stop and guide means 10 extends from the proximal ledge 8 to the top of the cut-away portion 11 of the vertical back 5.
  • the curved guide means 14 has a receiving edge 15 which, as is shown in Fig . 2 is positioned so as to receive the leading edge LE of the outlet web 3 of the printer 1 and is carried through a curved path to the exiting edge 16.
  • a receiving edge 15 which, as is shown in Fig . 2 is positioned so as to receive the leading edge LE of the outlet web 3 of the printer 1 and is carried through a curved path to the exiting edge 16.
  • a cut-away portion 18 at the exiting edge 16 of the curved guide means 14 for provision of a swinging flap 20 which is pivotably supported by a rod at point 21.
  • This flap is optional, and as shown in Figs. 7-10 is not utilized.
  • Extending distally from the proximal ledge 8 to the distal end of the base 7 of the refolding apparatus is a planar surface 9 which serves as the refolding surface.
  • This surface contains a spline 27 which extends from the proximal ledge 8 at an angle upwardly to the end of the base 7.
  • a depending flange 29 is at the extreme distal end of the base and fits snugly over the end of the printer 1 and depending posts 30 are at the proximal end of the base fitting snugly over the inlet end of the printer 1.
  • base 7 can rest on the top surface of printer 1, or it can be equipped with sockets for legs to accommodate printers of various heights.
  • Figs. 2-6 it will be seen that the folded stack S of paper contained in the box B on the supply side of the printer is fed into the printer and is driven by the sprocket drive D through the exit so as to engage the receiving edge 15 of the curved guide member 14.
  • the leading edge LE of the outlet web 3 is hand fed into the receiving edge 15 of the curved guide means 14 and exits at the exiting edge 16 where it is guided by the swinging flap 20 as is shown in Fig. 2.
  • the leading edge LE is projected toward the distal end of the base 7 of the apparatus. Therefore, as is shown in fig. 4, the leading edge is manually lated and pushed back against the stop 10 so that the fold FU will fall at the distal end of the base 7 on spline 27. Thereafter the next fold FD (in which the fold is directed downwardly) will fall by gravity against the guide means and stop 10 and from that point on, the operation is fully automatic.
  • the purpose of the spline 27 is to allow the edges of the paper to bend over toward the edges of the planar surface 24 and allow the air between the folds to be squeezed out, so that the stack refolds itself in the same fold pattern as it had on the supply side S in the box B.
  • the apparatus is small, compact and takes up very little space and has no moving parts. It is admirably suited for the personal computers and the personal terminals and printers used in the home and in the office, and does not require any more additional desk space than is required for the equipment per se.
  • the printer When the printing is finished, the printer should be manually operated to feed sufficient pages through to position the last printed page in the stack. Then the refolded stack can be separated and all the printed pages removed. It should be clear that it is possible with the apparatus of this invention to handle the full range of output of the printer, and also allow for the removal of some of the printed stack during the operation while the printing is taking place.
