Definitions

  • the present invention relates to a machine for folding and sealing at high speed sheets of paper such as letters, printed matter, forms and the like, with a view to their delivery by post in the form of letter cards with three flaps folded in accordion, without envelope.
  • Known devices for folding sheets of paper can be broadly classified into two categories, namely pocket folders and knife or blade folders.
  • the first are for example described in the patents DE 577 341 ( Figure 1) and US 1 832 376, 3 917 251 and 4 244 319, and the second are for example described in the patents DE 577 341 ( Figure 3) and 1 561 126, FR 2 455 513, GB 1 384 622 and 1 460 487, and in the publication "IBM Technical Disclosure Bulletin" volume 17, N-2 4, September 1974, pages 1098 and 1099.
  • feed means penetrate the sheet of paper into a pocket which is arranged in such a way that the path of the sheet of paper in the pocket makes an angle with the path which is imparted by the means of 'advanced.
  • the combined action of the advancing means and the stop forces the sheet of paper to form a fold which engages in the nip area of two cylinders rotating in opposite directions.
  • the two cylinders finish folding the sheet and send it either to an exit conveyor or to another pocket if a second fold is to be made.
  • pocket folders can operate at relatively high rates (some manufacturers advertise rates of over 10,000 sheets per hour depending on the size and quality of the paper), the rates are necessarily limited by the fact that the route followed by the sheets of paper is not linear but has one or more cusps depending on the number of pockets.
  • part of the glue tends to deposit in the. or the pockets and also on the folding cylinders, in particular in the case where the sheet must be folded in a three-fold accordion and that glue must be provided on both sides of the sheets of paper.
  • the glue thus deposited in the pocket (s) and possibly on the folding rollers tends to stain the following sheets of paper.
  • the information printed on the sheets of paper may become illegible after the recipient opens the letter cards.
  • Folding machines are also known which are similar to pocket folding machines insofar as they comprise a stop and two folding cylinders, but no pocket, and in which one of the two folding cylinders is a suction cylinder. Folders of this kind are for example described in the patents FR 2 508 880 and US 1 998 337. These folders present the same problems as folder folders.
  • one or two fixed blades are generally provided, which extend parallel to the direction of advance of the sheet of paper, in correspondence with the fold or plies to be formed , and one or two rods curved so as to fold the sheet of paper around an edge of the fixed blade to form a fold during the advance of the sheet of paper.
  • These folders have the advantage of being particularly simple and quick.
  • the present invention therefore aims to solve this problem.
  • the folding device shown in Figures 1 to 3 comprises a conveyor 1, constituted for example by an endless belt conveyor, a flat and thin bar 2, which is fixed and extends longitudinally a short distance above the strand upper of the belt 3 of the conveyor 1 near the side of the latter and a folding rod 4.
  • the bar 2 is fixed to at least one support 5 which is itself fixed to a frame (not shown).
  • the rear end 2a of the bar 2 is curved upwards so as to facilitate the engagement of the sheets of paper between said bar and the upper strand of the belt 3.
  • the folding rod 4 is fixed to at least one support, such as the support 6 shown in FIG. 3, which is itself fixed to the frame or to another element rigidly fixed to the chassis.
  • the folding rod 4 extends from a point 4a situated laterally on the side 1a of the conveyor 1 near its end for receiving the sheets to be folded and below the upper strand of the belt 3, then curves upwards and towards the conveyor 1 passing obliquely above the bar 2 and the upper strand of the belt 3, and then extends longitudinally towards the other end of the conveyor 1 to a second point 4b located beyond the end 2b of bar 2.
  • the sheets of paper 7 are oriented and positioned laterally by means which will be described later, in such a way that, when they arrive on the upper strand 3 of the conveyor 1, a marginal part 7a of the sheets 7 protrudes from the side of the conveyor 1 as shown in FIG. 2, and in such a way that the longitudinal edge 2c of the bar 2 is in alignment with a fold line 7b of the sheet 7 (in the figure 2, the fold line 7b is shown slightly offset laterally relative to the edge 2c of the bar 2 simply to make it more visible).
  • a holding device 8 is provided for holding the sheets of paper 7 in contact with the upper strand of the belt 3.
  • the belt 3 has perforations 9 ( Figures 2 and 3) in its part located between the bar 2 and the side 1b of the conveyor 1, and the holding device 8 is consisting of a suction box which is connected to a suction source (not shown), such as for example a vacuum pump or a suction turbine.
  • a suction source such as for example a vacuum pump or a suction turbine.
  • the upper strand of the belt 3 slides on the upper wall 8a of the suction box 8, which is provided with openings 11 corresponding to the perforations 9 of the belt 3 and elongated in the direction of movement of the latter.
  • the sheets 7 follow a continuous linear path, therefore without any turning point. It follows that the sheets 7 can follow each other at a short distance from each other and that the rate of the folding device can be very high, this rate being only limited by the quality of the paper and by the maximum speed of movement of the conveyor 1 It will also be noted that if the upper face of the part 7c is coated with glue lines as will be seen below, at no time does the bar 2, the belt 3 and the folding rod 4 come into contact with the glue.
  • the end 2p of the bar 2 is behind with respect to the end 4b of the folding rod 4 and that, as a result, the bar 2 is no longer inside the fold of the sheet 7 when the part 7c of the sheet is completely folded over the remaining part of the sheet. It therefore follows that the bar 2, the belt 3 and the folding rod 4 are not soiled by the adhesive.
  • the folding device 10 'shown in Figures 4 and 5 comprises a conveyor 1, a bar 2, a folding rod 4 and a pressure roller 12 which are identical to those of the folding device 10 shown in Figures 1 to 3 except that in this case the belt 3 of the conveyor is not perforated.
  • the holding device 8 ′ is constituted by a shoe 13 of elongated shape, which is urged towards the upper strand of the belt 3 by several springs 14 which bear on a fixed bar 15.
  • a second endless belt conveyor 16 17 is provided, the lower strand of which is in contact with the upper strand of the belt 3 of the conveyor 1.
  • the shoe 13 can be arranged next to the conveyor 16 or, preferably, above the lower strand of the belt 17 in order to press said lower strand against the upper strand of the belt 3 of the conveyor 1.
  • FIG. 6 to 8 schematically show a machine using two folding devices 10 ( Figures 1 to 3), for the folding and sealing of three-part letter cards.
  • the sheets 7 which are used to form the letter cards, are for example previously printed and personalized by means of a printer controlled by a computer.
  • Each sheet 7 comprises two transverse and parallel fold lines 7b and 7d, constituted for example by weakening lines or perforations intended to facilitate folding, and which define three flaps 7c, 7e and 7f as shown in FIG. 9a.
  • the machine shown in FIGS. 6 to 8 comprises a feed device 18 capable of delivering the sheets of paper 7 one by one in the direction of the arrow 1 (FIG. 6), a first margin rectification device 19 disposed at the outlet of the feed device 18, a first sizing device 21 disposed at the outlet of the margin rectification device 19 and capable of depositing two lines of glue 22 and 23 on the lateral edges of the flap 7c of the sheets of paper 7 ( FIG. 9b), a second margin rectification device 24 disposed at the outlet of the sizing device 21 and capable of modifying the direction of movement of the sheets 7 by 90 ° (arrow J in FIG.
  • a second device for sizing 25 arranged at the outlet of the margin rectification device 24 and capable of depositing a line of glue26 along another lateral edge of the flap 7c (FIG. 9c)

  • the feeding device 18 can for example be constituted by a rotary suction feeder, also called “Rotary" feeder. It is a well known device, which is for example described in patent DE 577 341 (FIG. 1), and it is therefore not considered useful to describe it in detail. It will simply be noted that this device comprises a conveyor device 34 capable of receiving and transporting a large number of sheets, generally several thousand sheets, and which can be refilled with sheets during operation, and a suction wheel 35 which delivers the sheets one by one at a very high rate (see also patent U S 2,058,979).
  • the margin rectification device 19 comprises an endless belt conveyor 36, which is oriented obliquely to the direction of advance of the sheets of paper 7 indicated by the arrow I and which is arranged between two support plates 37 and 38 located at the upper strand 39 of the conveyor belt 36 to support the parts of the sheets 7 which project on each side of the conveyor 36.
