12 Claims

1. A system for forming a sheeted roll of material from a continuous roll of the material, comprising:

a) an anvil roller for receiving and conveying said continuous material around a portion of the circumferential surface thereof and having a first rotational axis;

b) a knife roller adjacent said anvil roller and having a fixed knife blade extending from a circumferential surface of a roller body and having a second rotational axis, wherein said first and second rotational axes are parallel and are spaced apart such that said knife blade extends just to said surface of said anvil roller for severing said continuous material into consecutive sheets thereof when said knife roller and said anvil roller, having said continuous material therebetween, are synchronously counter-rotated;

c) a sheet winding roller adjacent said anvil roller and having a third rotational axis parallel to said first and second rotational axes, wherein said sheet winding roller is in nipped relationship to a sheet of said material on said anvil roller surface; and

d) means for lifting a sheet of said material from said anvil roller surface and directing said sheet onto said sheet winding roller for forming said sheeted roll of material from overlapping of said consecutive sheets.
