ABSTRACT OF THE DISCLOSURE An anti-clockspringing mechanism is disclosed for preventing clockspringing of a wound roll of web material within the cassette 10 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 means or ribs 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.
