Adapter for Accommodating Winding Cores of Diverse Widths

In the conversion of web goods rolled on winding cores, it is necessary to take a grip on one or both ends of the core at winding and unwinding stations. Such stations are commonly set up for handling cores of a particular length, having one or two mandrels positioned to receive a core of that length. When a core of another length needs to be accommodated, it is typical to unbolt the mandrel(s) and install others of a different size.

This disclosure describes an adapter suited to fit over the end of a winding mandrel so that a grip can be taken on cores of shorter length. In the Figure below, an installed winding mandrel enters the illustration from the left, its distal end rendered in cyan.

The adapter conveniently maintains a friction fit on the distal end of the mandrel, and further may be held in place by one or more releasable clips. Optionally, a diaphragm expansion chuck (shown by grey phantom lines on the right side of the illustration) may be present to take a more robust grip on a winding core.
