Adjustable sheet length/adjustable sheet count paper rewinder

In an improved paper converting rewinder of the type which includes means for continuously unwinding successive parent rolls of paper and forwarding the paper through the rewinder, means including a perforator cylinder for providing transverse lines of perforations across the paper at product sheet length intervals in the machine direction to define product sheets of the paper, means including a bedroll and a chopper roll having means for breaking the paper along lines of the perforations which lines are product roll length spaced in the machine direction to define product roll lengths of the paper consisting of a predetermined count of the product sheets, means for initiating such breaking of the paper each time said bedroll completes a predetermined number of whole revolutions, and means for winding each product roll length of the paper on a tubular core to thereby make successive product rolls of the paper, the improvement comprising means for adjusting sheet length and means for effecting integer changes in sheet count per said product roll without changing either the perforation cylinder or the bedroll, said means for adjusting sheet length and a sheet count comprising means for independently controlling the velocity of said paper relative to the surface velocities of said perforator cylinder and said bedroll, and for enabling said paper to slip relative to the surfaces of said perforator cylinder and said bedroll.
