Winding apparatus

摘要

An apparatus for slitting a web material (4) such as paper, plastic film and the like into a plurality of web materials and then winding the web materials to form a plurality of rolls (6,6'), the rolls being divided into two groups, one group of rolls (6) being arranged side by side and coaxially to each other at the front of the apparatus, the other group of rolls (6') being arranged side by side and coaxially to each other at the rear of the apparatus. Tracking rollers (12) are disposed on the upper side of one group of rolls and the upper side of the other group of rolls. Actuator means (18) press the tracking rollers against the corresponding groups of rolls with a contact pressure therebetween. One group of rolls and the other group of rolls are supported by carriage means (20). Drive means (24) moves the carriage means downwardly in response to the increases in diameters of the rolls to thereby enable the rolls to increase in diameters.
