Abstract
A flat compressible material is roll-formed into a cylindrical package by a belt drive. The diameter of the rolled package is controlled so that a fixed predetermined length of material forms a rolled package of a predetermined diameter. The length of belt drive in contact with the material is proportionate to the length of the material fed into the belt drive, and holds the finished package size to a predetermined diameter.
