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.

Abstract: A light-tight cassette, and method of making same, for enclosing and dispensing a roll of photosensitive web material. The cassette comprises a folded fiberboard housing having a plurality of housing wall portions with oppositely projecting lateral edges which define opposite sides of the housing. The plurality includes two planar wall portions that extend perpendicularly to each other to respective ends thereof which are disposed in spaced alignment to provide an opening between them. Two extruded plastic light-locking members are attached to those wall portion ends, respectively, one such member extending across the opening toward the other member to form a web exit passageway therebetween. The one member includes a resiliently flexible, inwardly projecting cantilever portion that is biased toward an opposing portion of the other member, both such portions having light-locking material thereon.
