Abstract
An intercore for mounting a hollow photographic web roll core and to transmit rotation from an elongated spindle to the core, which spindle has one or more axially extending ramps which slope radially outward in a direction away from a front end. The intercore includes a bore to removably receive the spindle by insertion of the spindle front end first into the bore. At least one slot is present in the intercore, carrying a lug which can move radially within the slot and which is positioned such that insertion of the spindle front end first into the bore causes each lug to ride on a corresponding ramp and be urged radially outward through its carrying slot and into engagement with a hollow core positioned over the intercore. An elongated spindle is provided in another aspect, for insertion into a bore of an intercore which mounts a hollow photographic web roll core for rotation. The spindle has a front end, a rear end adapted to be rotationally driven, and one or more axially extending ramps which slope radially outward in a direction away from the front end. A drive assembly can use the intercore and the spindle together.
