  • a buckle plate for sheet manipulating apparatus comprises a plurality of sheet control members mounted in a frame so that the control members can be moved between a first position in which they provide deflecting surfaces for deflecting a sheet and a second position in which the control members act as stop members for locating a sheet which is to be folded, the second position being adjustable in accordance with the size of the sheet and the position of the fold on the sheet.
  • control members are slidably mounted in the frame so that they can be moved in unison between the first position and the second position.
  • the positions of the sheet control members may be adjustable so as to vary the angle of a line of deflecting surfaces or stop members relative to the leading edge of a sheet.
  • the buckle plate may include a position adjusting mechanism at each side of the frame arranged to be adjusted separately so as to vary the angle of a line of deflecting surfaces or stop members relative to the leading edge of a sheet.
  • each position adjusting mechanism comprises a toothed belt drive coupled to a carrier on which the control members are mounted.
  • the positions of the sheet control members may be adjustable by an arrangement of cams so as to vary the angle of a line of deflecting surfaces or stop members relative to the leading edge of a sheet.
  • the buckle plate may also include an auxiliary position adjusting mechanism located substantially centrally of the frame to provide fine adjustment of the positions of the control members independently of the position adjusting mechanisms at each side of the frame or the arrangement of cams.
  • the auxiliary position adjusting mechanism may comprise a screw-threaded rod arranged to vary the position of a carrier on which the control members are mounted.
  • the buckle plate may be provided with guide members arranged to direct a sheet towards the second position of the control members.
  • the guide members may comprise pairs of fingers between which a sheet passes when travelling towards the second position of the control members.
  • the pairs of fingers may be mounted on the ends of pairs of guide rods which extend along the frame.
  • the invention also resides in a paper manipulating machine incorporating a buckle plate as defined in the nine preceding paragraphs.
  • the paper manipulating machine comprises a base 1 on which is mounted a loading table 2 of a bottom feed conveyor 3, a sidelay 5, a roller assembly 6, an upper buckle plate 8 and a lower buckle plate 9.

  • the air issuing from the air outlet slots 25 and 28 raises the stack 22 of sheets above the surface 20 of the loading table 19 so that the bottom -sheet can be removed from the stack by a suction roller 37 located between the loading table 19 and the feed table 42.
  • a third control arrangement 38 controls the pressure of the air supplied in accordance with the height of the stack of sheets on the loading table 19.
  • the suction roller 37 is arranged to rotate so that it carries the bottom sheet of the stack 22 through a gate 39 and onto the sidelay 5.
  • a compressor/vacuum pump (not shown) mounted in the base 1 provides a supply of air under pressure to the two ducts 23 and also provides a vacuum to operate the suction roller 37.
  • the supply of air under pressure may also be controlled in accordance with the quality and weight of the sheets being moved by the suction roller 37.
  • the suction roller 37 is rotated by an electric motor 40.
  • the sidelay 5 is located above a flat, substantially horizontal, surface 41 of a feed table 42 along which sheet 43 is to be transported from the suction roller 37 to the roller assembly 6.
  • the sidelay 5 comprises an endless belt 44 of ⁇ olyurethane or other suitable flexible material the upper reach of w rich extends the full length of the feed table 42 to form a sheet comeyor 46.
  • the endless belt 44 which is approximately ten centimetres in width, extends at an angle of two degrees to a side rail 47 whhith also extends along the surface 41 of the feed table 42.
  • the twc degree angle between the endless belt 44 and the side rail 47 ensure: that the edge of the sheet 43 is maintained in contact with the siide rail 47 as the sheet 43 is moved along the surface 41.
  • the sheet 43 is held in contact with the surface of the sheet conveyor 46 by an assembly 48 of sixteen steel balls 49 held captive in co-operating sockets 51 and which press on the sheet 43 and the sheet conveyor 46 by gravity.
  • the balls 49 may also be formed from a suitable material such as glass, plastics material or nylon and are retained in the sockets 51 by a retaining bar (not shown) which extends above the balls 49.
  • the sidelay 5 including the endless belt 44, the side rail 47 and the assembly 48 of balls is movable across the surface 41 of the feed table as a unitary whole in a single movement to cater for the size of the sheets 43 being conveyed.
  • Coarse adjustment of the position of the sidelay 5 is provided by downwardly extending abutments on the lower surface of the side rail 47 which fit into correspondingly shaped holes 53 in the surface 41 of the feed table 42 best seen in Figure 7 in which various parts have been removed.
  • Two rows of the holes 53 at opposite ends of the feed table 42 provided a variety of different positions of the sidelay 5 depending on the size of the sheets being conveyed.
  • the sidelay 5 is simply moved so that the abutments fit into the particular holes 53 which are suitable for the size of the sheets 43 being conveyed.
  • Fine adjustment of the position of the sidelay 5 is provided by a screw-threaded member 54 which engages the side rail 47 and can be tightened or slackened by a control knob 55 to effect the adjustment.
  • a screw-threaded member 54 which engages the side rail 47 and can be tightened or slackened by a control knob 55 to effect the adjustment.
  • two screw threaded members which engage the side rail at opposite ends are arranged to be adjustable independently to vary the angle of the sidelay 5 relative to the direction of travel of the sheets.
  • the roller assembly 6 to which the sheets 43 are moved by the sheet conveyor 46 of the sidelay 5 comprises a central or fixed roller 57 which co-operates with two fold rollers 58 and 59 and with a feed roller 60.
  • the central roller 57, the two fold rollers 58 and 5 9 and the feed roller 60 are steel rollers each having ten hard rubber meshing portions 61 provided with splines at spaced positions along their lengths.
  • the rollers of the roller assembly 6 are driven by an electric motor 62 through helical gears 63.
  • the nips between the central roller 57 and each of the two fold rollers 58 and 59 are adjustable by respective calipers 64 and 65 having gaps 66 which vary in accordance with the dimensions of the nips so that inserting a specimen of a sheet to be folded into the gaps 66 automatically sets the nips to suit the specimen.
  • the nip between the central roller 57 and the feed roller 60 is adjustable by a caliper 68 having a gap 69 which varies in accordance with the dimension of the nip so that inserting a specimen of a sheet to be fed into the gap automatically sets the nip to suit the specimen.
  • the movable arms 72 of the calipers 64 and 65 are formed by blocks in which the spindles 73 of the fold rollers 58 and 59 are journalled so that opening the gaps moves the fold rollers 58 and 59 away from the central roller 57.
  • the movable arm 74 of the caliper 68 (see Figure 13) is formed by a block in which the spindle of the feed roller 60 is journalled so that opening the gap moves the feed roller 60 away from the central roller 57.
  • the gaps in the calipers 64, 65 and 68 are.arranged to be opened by a cam 77 which engages the blocks forming the movable arms, the cam being operated by a handle 78 acting through a Bowden cable 79.

  • the ends 94 provide deflecting surfaces for deflecting a sheet 43, but if the control members 89 are moved to a second position as illustrated in Figure 11 the ends 94 act as stop members for locating a sheet 43 which is to be folded, this second position being adjustable in accordance with the size of the sheet 43 and the position of the fold on the sheet.
  • control members 89 of the upper buckle plate 8 will have been set to the first position so that the ends 89 act as deflectors which deflect the leading edges of a sheet 43 emerging-from the nip between the rollers 57 and 60 into the nip between rollers 57 and 58.
  • a sheet 43 may be folded by the lower buckle plate 9, deflected by the lower buckle plate 9 or guided into the slitting, scoring and perforating arrangement 10 for delivery out of the rear end of the machine. If the sheet is to be folded by the lower buckle plate 9 the sheet control members 89 will have been set to a second position and the leading edge of the sheet moves between the guide fingers 86 until it encounters the ends 94 of the control members 89 which act as stop members.
  • the movement of the leading edge of the sheet 43 is halted, but the portion _ of the sheet emerging from the nip between the rollers 57 and 58 continues to move, producing a fold, the doubled end of which enters the nip between the fixed roller 57 and the fold roller 59.
  • the folded sheet emerging from the nip between rollers 57 .and 59 then enters a nip between two main perforator rollers 97 and 98 and then passes under a plurality of bale arms 99 onto the sheet conveyor 12 which is formed by a cord conveyor arrangement.
  • the sheet conveyor 12 is arranged to feed a stacker conveyor 13 which is driven at a speed one fifteenth that of the sheet conveyor 12 so that the delivered sheets form a stepped stack at the output end 14 of the machine.
  • the control members 89 of the lower buckle plate 9 will have been set to the first position so that the ends 89 act as deflectors which deflect the leading edge of a sheet 43 emerging from the nip between the rollers 57 and 58 into the nip between rollers 57 and 59.
  • the sheet 43 emerging from the nip between rollers 57 and 59 enters the nip between main perforator rollers 97 and 98 which may be provided with slitting, scoring or perforating cutters (not shown) to slit, score or perforate the sheet.
  • the sheet then passes to the sheet conveyor 12 and is fed to the stacker conveyor 13 for delivery to the output end 14 of the machine.
  • the slitting, scoring or perforating cutters are removed from the rollers 97 and 98.
  • the sheets 43 may by-pass the main perforator rollers 97 and 98, the sheet conveyor 12 and the stacker conveyor 13 and be slit, scored or perforated by the slitting, scoring and perforating arrangement 10 and delivered to the rear of the machine.
  • the lower buckle plate 9 is removed and the arrangement 10, which is mounted for pivotal movement about a pivot 95, is swung from the inoperative position shown in Figure 16 to the operative position shown in Figure 15.
  • the arrangement 10 comprises a rotatable blade 100 which co-operates with a rotatable channel 101 to slit, score or perforate a sheet 43, the particular blades 100 which perform each of these functions being interchangeable.
  • the blades 100 may also be adjustable to cater for sheets 43 of paper and cardboard of different grades of thickness.
  • Guide members 106 are automatically located to direct a sheet 43 emerging from the nip between the rollers 57 and 58 towards the blade 100 and the co-operating channel 101 when the arrangement 10 is in the operative position.
  • An outlet 108, aligned with the guide members 106 is arranged so that sheets emerging from between the blade 100 and channel 101 are ejected from the rear of the machine.
  • a sheet passing from the blade 100 and channel 101 to the outlet 108 travels in a substantially straight line path and does not have the curl usually associated with slitting, scoring and perforating arrangements.
  • control members 89 are moved in unison, in other arrangements the control members 89 may be moved singly or in groups, for example when manipulating polygonal sheets instead of the rectangular sheets shown in the drawings.
  • sheet conveyor 46 is formed by a single endless belt 44, in other arrangements the sheet conveyor may be formed by a plurality of endless belts or cards arranged parallel to one another.
