A web-chopping and sheet-winding apparatus comprising an unwinder for unwinding a supply roll of continuous flexible web which may be adhesive on at least one side. A knife roller including at least one fixed transverse knife blade extending from the surface is in nipped relationship with an anvil roller, the height of the knife blade being greater than the thickness of the web. The anvil and knife roller spacing is such that the knife blade extends just to the surface of the anvil roller, thereby chopping the continuous web into sheets as the anvil and knife rollers turn synchronously with the web passing therebetween. A tape core roller in nipped relationship receives the chopped sheets sequentially, the leading edge of each sheet being lifted from the anvil roller by any of a plurality of novel means.
A system for forming a sheeted roll of material from a continuous roll of the material, comprising:
