Abstract (en)

[origin: US5961435A] A folding device (10) includes: two cam-controlled folding knives (20, 21) that are vertically moveable relative to each other; a run-in table (60) vertically shiftable synchronously with the folding knives; and a counter-pressure line (80) having at least one pressure cylinder (82) per sliding block (84). The shafts (30, 31) and their drive systems (50, 51) are shiftable in mutually opposed vertical directions and are synchronized, e.g. electronically or via T-type gears (53, 54) having a common motor (52). At least one shaft (31) with its motor (51) is shiftable in a linear carriage (37) of a vertical linear slideway (38). The folding knives (20, 21) are rotatably supported at linear carriages (24, 25) guided on linear slideways (27, 28) and connected to cam disks (40, 41) which, synchronously with at least two eccentric disks (44) fixed to the shafts (30,31), bear on associated rocker levers (45). A measuring system (86) behind the sliding blocks (84) is adapted for travelling across the entire working width (A). A control display unit (90) continuously shows the height shifting of the folding knives (20, 21), of the run-in table (60) and of an upper shaping plate or upper table (65).
