Apparatus for slitting belt

A belt-slitting machine (10) comprising a frame (12), a work table (16), a first carriage (18) for supporting a supply roll (30) of belt material (51) and a second carriage (20) for supporting takeup rolls (32) of slit belt material (54). Motors/gearboxes (40, 42) turn spindles (28) in order to unwi...

More Information
Summary:A belt-slitting machine (10) comprising a frame (12), a work table (16), a first carriage (18) for supporting a supply roll (30) of belt material (51) and a second carriage (20) for supporting takeup rolls (32) of slit belt material (54). Motors/gearboxes (40, 42) turn spindles (28) in order to unwind the supply roll (30) of belt material and to roll up the slit webs of belt material into rolls (32). Coupler assemblies (102,104) are provided between cylinders (40, 42) and spindles (28). Coupler assemblies (102, 104) provide positive torque between cylinders (40, 42) and spindles (28) as spindles (28) deflect due to the weight of the belt material and cause the ends of the spindle to angularly deflect about the rotation axis of the spindle and to rise vertically a small distance due to the deflection. An outfeed belt divider apparatus (108, 112, 114) is provided for keeping the slit rolls of belt material separated as the belt material winds around into rolls (32). An edge position control device is provided for sensing the edge of the belt material. Carriages (18, 20) are repositionable laterally in response to the detected position of an edge of the belt material in order to keep the belt material aligned with cutter disks (68). In addition, tension rollers (44) and pinch rollers (60, 78) are provided in addition to drive rollers (62, 80) to control the movement of the belt material past the cutter disks (68).
