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).
Folding device (10) including two motor-driven folding knives (20,21) which are vertically movable relative to each other by means of cam disks (40, 41) supported on shafts (30, 31) having associated respective drive systems (50, 51), including a run-in table (60) for material (M) to be folded and including a counter-pressure line (80), wherein the shafts (30, 31) are coupled for synchronized movement and, together with their drive system (50, 51), are adapted for shifting in synchronism in mutually opposing vertical directions,
A knife pleating system (10) including two motor-driven folding knives (20,21) which are vertically movable relative to each other by means of cam disks (40, 41) supported on shafts (30, 31) having associated respective drive systems (50, 51), including a run-in table (60) for material (M) to be folded and including a counter-pressure line (80), wherein the shafts (30, 31) are coupled for synchronized movement and, together with their drive system (50, 51), are adapted for shifting in synchronism in mutually opposing vertical directions,

A folding device (10) including two motor-driven folding knives (20, 21) which are vertically movable relative to each other under control of cam disks (40, 41) supported on rotatable shafts (30, 31) having associated drive systems (50, 51), including feeding means for flat material (M) to be folded as well as a counter-pressure line (80) and a height-adjustable run-in table (60) for feeding the material (M) to be folded at a center level of the folding knives (20, 21), wherein a drive system of a lower folding knife (21) is adapted to be lifted and lowered, respectively, for adjusting a folding height (H) of the material (M).
