Abstract
A light-tight cassette (10) has an anti-clockspringing method for preventing clockspringing of a wound roll of web material (14) within the cassette (10) during storage and shipment. The web material (14) is mounted on a tubular web core (12) arranged to rotate about an axis within the cassette (10). Cassette (10) has at least one end cap (22) having a tubularly shaped hub member (34). Hub member (34) has a diametrically extending bar (38) for receiving an anti-clockspring means comprising a fork (44) having a central member (52) comprising spaced anti-rotation arms (42,44) for receiving bar (38). Fork (44), moreover, comprises at least one flexible latch finger (46) that latchingly engages the end cap (22) and a flexible lock finger (48) that is wedged between and into an annular gap formed when the hub member (20) is inserted into the web core (12) for locking the web core (12) against rotation.
