ABSTRACT:
A drum is mounted rotationally in a cassette. A series of roller shafts are arranged around the drum and move radially. A web inserted into the cassette is forced against the drum by the roller shafts and causes the drum to move in frictional engagement with the web. As additional web material is forced into the cassette, convolutional layers of the web built on the drum forcing the roller shafts outwardly and permitting the drum to wind the web without any rotational motion imparted to the drum except for that of the web.
