<p>A method and apparatus for the preparation of a wound roll (6) of a web of material (12) by utilizing a surface windup device with a primary lay-on roll (1) that feeds the web of material (12) onto a rotating core, winding the web (12) onto the core to form a roll (6) by driving the roll of material (6) with a secondary lay-on roll (2), the differential in surface speed between the primary and secondary lay-on rolls (1,2) controls the tension of the web (12) as it is wound. Also incorporates are a retractable cutting roll (5) and knife (4) assembly that is moved into position to cut the web of material (12), assist in transferring the web of material (12) to a new core and then retracts to a position that does not hinder winding the new roll of wound material (6). <IMAGE></p> |
