ROLLER DRIVING DEVICE FOR SLITTER

PROBLEM TO BE SOLVED: To prevent deterioration in winding quality, in a plurality of guide rollers for a slitter by eliminating delay of the guide roller especially having a smaller embracing angle so as to synchronously rotate, and by eliminating a deviation in a web width direction. SOLUTION: In the slitter, the wide web is cut in a longitudinal direction into a plurality of narrow webs, and the cut narrow webs are wound around winding shafts arranged so as to separate from each other in a vertical direction or a back-and-forth direction. The plurality of guide rollers 1, 2, 3 receiving the webs paid out from a web roll at an established speed is made to carry out corotation that obtains rotation force from contact with the webs touching on roller surfaces. The rollers are connected with each other by a transmission means capable of synchronously rotating by toothed pulleys 32, 33, 34, and a toothed belt 35. COPYRIGHT: (C)2004,JPO&NCIPI
