Apparatus for winding stiffened coreless rolls, and method

摘要

The device comprises a product paper feeder for moving product paper from a source of product paper downstream along a product paper feed path and a web roller for forming a spiral roll from product paper fed downstream along the product paper feed path. It has a stiffening paper feeder for feeding stiffening paper from a source of stiffening paper downstream along a stiffening paper feed path, the stiffening paper feed path joining the product paper fed path upstream of the web roller. It has a paper cutting assembly including a cutter roll located between the feed paths, a cutter knife on the cutter roll and drive for rotating the cutter roll. A product paper anvil blade is located on the side of the product paper feed path away from the cutter roll. A stiffening paper anvil blade is located on the side of the stiffening paper feed path away from the cutter roll.
