摘要:
A folding apparatus for folding sheets of flexible sheet materials, which includes a feeding mechanism (11, 17) for feeding sheets of material, a folding mechanism including a pair of rollers (11, 13) having a nip (23) into which a sheet of material (7) is inserted to create a fold (7b), and an inserter mechanism (21) for inserting a sheet (7) into the nip (23). The inserter mechanism (21) includes knife element (29) having an edge (31) that is arranged to engage a sheet (7) along a designated fold line (7a) and to insert said sheet (7) into the nip (23) to produce a fold (7b) along said fold line (7a). The inserter mechanism (21) is constructed and arranged to insert the sheet (7) into the nip (23) while the sheet (7) is positively engaged by the feeding mechanism (11, 17).
摘要:
A buckle plate (8 or 9), for use in a machine which manipulates i.e. folds or deflects sheets of paper, cardboard or the like, comprises a rectangular frame (81) having a multiplicity of pairs of transversely extending guide members (84) between which a sheet slides. A carrier (88) extending transversely of the guide members supports a plurality of sheet control members (89) in spaces between the guide members so that the control members can be moved between a first position in which they form deflecting surfaces for deflecting a sheet and a second position in which they act as stop members for locating a sheet to be folded. The second position is adjustable in accordance with the size of the sheet and the position of the fold. The carrier is slidably mounted in the frame so that the control members can be moved in unison between the first and second positions.

A creasing machine (1) for forming creases in sheets (11) of flexible material, said creasing machine (1) including a creasing mechanism (5), a transport mechanism (3) for transporting sheets (11) of material through the creasing mechanism, and a control means (7) for controlling operation of the creasing mechanism (5) and the transport mechanism (3), said creasing mechanism (3) including first and second creasing members (25,27) and a drive mechanism (28) for driving the creasing members (25,27), wherein the creasing members (25,27)are arranged to move in the direction of movement of the sheet (11) and at least one of said creasing members (25,27) is moveable towards the other creasing member (25,27) to produce a crease in a sheet (11) located between those members (25,27), and wherein the control means (7) is arranged to substantially match the speed of movement of the creasing members (25,27) with the speed of the sheet to enable the sheet to be creased while moving.
摘要:
An apparatus for creasing and folding sheets of flexible sheet materials. The apparatus includes a creaser mechanism (1) for creasing sheets, a fold mechanism (100), a feed mechanism for feeding sheets from the creaser mechanism to the fold mechanism (100); and a control system for controlling the apparatus, wherein the fold mechanism (100) includes a pair of rollers (111, 113) having a nip (123) into which a sheet of material (7) is inserted to create a fold (7b), and an inserter mechanism (121) for inserting a sheet (7) into the nip (123), said inserter mechanism (121) including a knife element (129) having an edge (131) that is arranged to engage a sheet (7) along a crease and to insert said sheet (7) into the nip (123) to produce a fold (7b) along said crease.

摘要:
An arangement for the remote control of the setting of the nip between a fixed roller (57) and an adjustable roller (58) of apparatus which manipulates i.e. folds, slits, scores, perforates or deflects of paper, cardboard or the like, comprises a caliper (64) coupled to the adjustable roller and having a gap (66) the dimension of which varies in accordance with the dimension of the nip. By opening the caliper land inserting a specimen of a sheet in the gap the nip between the rollers is adjusted automatically to suit the specimen. The movable arm (72) of the caliper is formed by a block in which a spindle (73) of the movable roller is journalled and which is moved by a cam (77) operated by a handle acting through a Bowden cable (79).
