An improvement in paper converting rewinders in which bulk rolls of paper are converted into consumer product rolls of paper such as tear-separable multi-sheet rolls of toilet tissue or paper towels. In such rewinders of the type which include a perforator cylinder, and a bedroll/chop-off roll combination, changes in sheet length and/or sheet count commonly require changing one or more of such rotating, paper contacting machine elements. The present invention enables broad changes in both sheet length and sheet count in such rewinders without changing either the perforator cylinder or the bedroll or the chop-off roll. The invention also enables adjustments to assure true cross machine direction orientation of inter-sheet lines of perforation throughout the range of adjusting sheet length and/or sheet count per product roll.
