ABSTRACT:
A cassette for wound web material has an anti-clockspringing mechanism for securing the web against movement during storage and shipment. The roll of web material is mounted on a tubular core (12) arranged to rotate with the roll of material within the cassette (10).
The cassette (10) has a jacket (16), end caps (22), and core plugs (34) for securing the end caps (22) onto end edges (18) of the jacket cassette (10). Each of the end caps (22) has a plurality of radially extending spaced apart stop (32). The anti-clockspringing mechanism comprises an arm (56) on the core plug (34) movable between a core-blocking position in which the arm (56) extends into a space between two adjacent ribs (32) and is retained therebetween for preventing rotation of the web roll, and a core-unblocking position on which the arm (56) is disengaged from the ribs (32) for allowing web rotation.
