ABSTRACT:
An anti-clockspringing mechanism for a web-roll comprises a unitary lock member having a cylindrical body rotatably mounted in a sidewall of the cartridge. A flange on a web-spool on which the web-roll is wound is provided with an annular lip having alternately spaced lugs and notches. The body has a handle on one side thereof extending toward the exterior of the cartridge, and a lock member on the opposite side of the body extending into the interior cavity of the cartridge. The lock member is in alignment with a sector of the annular lip and lies in the plane of the annular lip. The lock member further comprises at least one shoulder projecting from the opposite side of the body. The lock member is moveable between an unlocked position, in which the shoulder is withdrawn from a lip notch and is out of alignment with the lip lugs for allowing the web-spool to freely rotate, and a locked position in which the shoulder is in alignment with the lip and nests within a lip notch in a position transverse to the lip lugs for preventing or blocking the web-spool from rotating.
