    摘要: A device for making cuts in the direction of the advance of pieces of thin material, for example in slips of paper along the path on which they are fed, a cutter carrying drum (1) and a cutting bed drum (2) rotating in opposite directions to each other. The drum (1) carries at least one peripheral cutter (3, 3', 3'') whose cutting edge (103) is orientated in the direction of advance of the pieces of material and is curved coaxially with the drum (1), projecting radially beyond it. According to the invention, the cutter (3, 3', 3'') is fixed on the cutter carrying drum (1) by means of a removable (5, 7) base (4, 4', 4'') which has an intrinsic elasticity such that it provides a certain sprung support of the cutter (3, 3', 3'') alternatively and in combination in the radial direction and in the direction of oscillation about an axis transverse to the cutting edge (103) of the cutter (3, 3', 3''), in particular substantially parallel to the axis of the drum (1).

    摘要: Box blank-forming apparatus (60) is provided which includes a feeder assembly (62) and a scoring/slotting assembly (64) each provided with adjustment structure (62a, 64a) to facilitate makeready adjustment of the apparatus (60) between production runs. The feeder assembly (62) preferably includes a reciprocal pusher element (170) operable to successively engage sheets (30) to be formed into box blanks (36). The element (170) is supported by a pair of elongated, threaded, axially rotatable, fore and aft translatable positioning screws (146, 148), so that upon rotation of the screws (146, 148), a reference position of the pusher element (170) may be varied. Adjustment of the assembly (64) is accomplished by means of compensators (292, 294) which are respectively coupled to associated slotter wheel and scoring wheel shafts (288, 286). Operation of the slotter wheel shaft compensator (294) serves to adjust the circumferential positions of the fixed slotter knives (358), whereas operation of the scoring shaft compensator (292) varies the position of the adjustable knives (360) through the medium of transfer gears (384). Servo-sensors (438-442, 446-448 and 270) are used to continuously monitor the lateral and circumferential positions of the scoring/slotting stations (296-304) and a reference position of the pusher element (172), so that precise makeready adjustments can be accomplished.

    摘要: A transformation unit transforming a first substrate in a continuous band (2) into a second substrate in the form of transformed pieces with a predetermined length (3), the band (2) having a constant entry speed, comprises a first motorized arrangement (4) for performing a first feed driving (F) of the band (2), a sheet cutter (12) with rotary tools (13, 14) for cutting the band into pieces (3), a second motorized arrangement (17) for performing a second feed driving of the substrate (2, 3), positioned in the immediate vicinity of the sheet cutter (12), and at least one station (21, 22, 23) with rotary tools (26, 27, 28, 29, 32, 33) to transform the pieces (3). A speed of rotation (38, 41) of the second arrangement (17) varies during a rotation cycle of the tools (13, 14) of the sheet cutter (12), having a constant tangential speed phase (46) substantially equal to the speed of rotation of the tools (13, 14) of the sheet cutter (12), during which the cutting is done, a speed decrease phase (43), during which a band length (2), depending on the difference between the length of the piece (3) and a development of the tools (26, 27, 28, 29, 32, 33), is kept upstream from the second arrangement (17), and a speed increase phase (44), during which the substrate (2, 3) is discharged downstream from the second arrangement (17).
