  • These apparatus utilize as a rule air-pervious movable supports such as rotary drums or perforated belts through which an air suction is produced in order to press the sheets by suction against these supports. It is thus possible to slow down one sheet in relation to the next sheet so that the various sheets eventually received on a conveyor belt driven at a relatively low speed overlap one another.
  • the US. Pat. No. 2,580,469 describes an apparatus for receiving flat articles cut from a continuous web by means of a rotary cutter so as to form a row of sheets on a discharge conveyor comprising, downstream of the cutter, an upper cam and a lower cam and a lower cam mounted for rotation about two transverse shafts respectively, the cut articles being adapted to move between these cams, the upper cam having a gradually decreasing radius; the cam with the increasing radius has a lower coefficient of friction than that of the cam having the decreasing radius, whereby the article is carried along by said lower cam.
  • Means are provided for rotatably driving said cams in opposite directions at a speed such that the tangential speed of the lower cam be equal to the linear speed of the article at the time of its engagement.
  • Feed rollers are arranged upstream of the cutter device and driven at a tangential speed' equal to the linear speed of the cut articles.
  • the aforesaid cams are operatively interconnected through pinions and also connected through trains of gears or a chain transmission to said feed rollers and to said rotary cutter.
  • each sheet is positively prevented from abutting against the trailing edge of the preceding sheet; in the other hand, this apparatus does not comprise any rotary member in which an internal suction is produced.
  • This invention is characterized in that the apparatus constituting the subject-matter thereof, for receiving sheets cut from a web by a rotary cutter and depositing upon a discharge conveyor a succession of sheets wherein each sheet partially overlaps the preceding one, comprises downstream of said rotary cutter at least one pair of transverse cylinders consisting of an upper cylinder and a lower cylinder forming therebetween a passage through which the cut sheets are adapted to move with a minimum clearance, said upper cylinder comprising on one portion of its outer periphery at least one cylindrical boss or projection concentric to said upper cylinder, said lower cylinder comprising, on one portion of its outer periphery, at least one recess formed with a cylindrical bottom coaxial to said lower cylinder, both cylinders being rotatably driven in opposite directions so that during this movement the cylindrical boss'of said upper'cylinder engages tangentially said cylindrical'bottom surface of said recess formed in said lower cylinder and at a same linear speed of same direction as the feed rate of the cut sheets andlower than this speed each time
  • the apparatus is designed for receiving sheets cut from a continuous web ,1 consisting, for example, of paper, although the invention is not limited to this specific material.
  • the sheets are cut by means of a rotary cutter 2 known per se arranged upstream of the apparatus and comprising essentially a blade 3 rotatably rigid with a shaft 4 and adapted to coact with a counter-blade 5.
  • the shaft 4 is rigid with a pinion 6 and rotatably driven at a speed depending of course on the format or size of the cut sheets, from a power pinion 7, through a pair of lay pinions 8 and 9.
  • These feed rollers 12 are rotatably driven from a device to be described presently at a tangential speed slightly greater than the tangential speed of the rotary cutter which corresponds to the size of the cut sheet, so that the rollers 11 and 12 produce a slight relative spacing between the successive cut sheets.
  • the sheet receiving apparatus comprises downstream of the cutter 2, a slowdown device designated as a wholeat l3 and comprising essentially a set of upper cylinders 14 rigid with a transverse horizontal shaft 15, and a set of lower cylinders l6 rigid with a transverse and horizontal lower shaft 17.
  • the slow-down device 13 also comprises an upstream feed device comprising upper idle rollers 18 co-acting with lower driven rollers 19, and a downstream feed device comprising upper idle rollers 21 co-acting with lower driven rollers 22.
  • the shaft 17 carrying the lower cylinders, 16 is rotatably rigid with a pinion 23 meshing with another pinion 24 rigid with the shaft 15 carrying the upper cylinders 14.
  • Pinion 23 is in constant meshing engagement with an intermediate or lay pinion 25 meshing in turn with a pinion 26 rigid with a shaft 27 carrying the lower rollers 19.
  • This pinion 26 is also drivingly connected via pinion 28 to another pinion 29 rigid with a shaft 31 carrying the lower driven rollers 12.
  • the aforesaid pinion23 is operatively connected through an intermediate pinion 32 to another pinion 33 rigid with a shaft 34 carrying the lower driven rollers 22.

  • the distance between centers of shafts and 17 is twice the radius R of boss 14a and recess 16a, so that at each revolution of cams 14 and 16 (revolving at the same angular speed) the boss 14a engages the recess 16a and rolls thereon without slipping.
  • the arc AB covered by the contour of boss l4a cor corresponds to about 30 and is definitely smaller than the arc CD along which extends the recess 16a (about 75).
  • sheet 1a is braked or slowed down while the next sheet continues to be driven at the tangential speed of rollers 18 and 19. Under these conditions, an overlap of about 10 mm. is formed between the two sheets.
  • the sheet-receiving apparatusv comprises at its outlet an endless conveyor belt 38 driven at a moderate speed definitely lower than the linear speed of the sheets emerging from the feed rollers 21 and 22.
  • cam 16 holds with its portion 16b the sheets between the two tables 30 and 36.
  • the apparatus according to this, invention may be utilized for 'a wide range of cut sheet sizes. In fact,it is only necessary to provide in the means for rotatably driving the cylinders 14 and 16 a variable-speed transmission mechanism permitting of adjusting at the pinching time a constant ratio of the tangential speed corresponding to the cut size to the tangential speed of boss 14a and recess16i1.
