Abstract
A spool for a strip of film or other web material has a core and an elongate slot through the core for receiving an end portion of the strip. A separate keeper for retaining the end portion in the slot includes a first portion that is snapped into the slot and holds the end portion firmly against one surface of the slot. The keeper has a second portion that is engageable with the strip outside the slot for holding the strip against an arcuate portion of the core. The keeper can be latched in either a first position in which the keeper is partially inserted into the slot during insertion of the end portion into the slot, or a second position in which the keeper is fully inserted into the slot.
Claims13
In a spool for a strip of film or other web material having an end portion that is to be attached to the spool before winding the film onto the spool, the spool having an elogate core with an outer surface, the core being rotatable about an axis through the core for winding film onto the outer surface and unwinding film from the outer surface, and the core having first and second spaced surfaces defining a slot beginning at the outer surface, passing essentially diametrically through the core and ending at the outer surface, said slot being for receiving an end portion of the film, the improvement comprising:
- a film keeper for retaining the film end portion in said slot, said keeper having a first portion shaped to enter said slot radially through said outer surface of said core and hold the film end portion firmly against said first surface of said slot and a second portion pivotable relative to said first portion to engage the film outside said slot for holding the film against a curved portion of said outer surface of said core.
