Multiple fixed-position film centerwinder and method for winding web material

摘要

The invention is a centerwinder for receiving and winding web material sequentially on one of at least two fixed shafts. The two or more shafts are desirably positioned vertically to one another in a stationary structure and eliminate the need for a powered turret assembly. A lay-on roll assembly can be used that pivots in and out as well as up and down for serving the respective shaft locations. A cylinder linkage provides the same or constant force against the winding roll on either the upper or the lower shaft. Transfer rolls in desirable embodiments are automatically pivoted into the proper position for a fully automatic transfer or to assist the operator during a manual cut and transfer.
