Abstract
A tail end of a web is attached to a winding core via a two-component mechanism having a core component attached to the core and a web component attached to the web, the two components being attached to each other in releasable fashion. The mechanism assists startup of winding. Upon completion of unwinding, the web component detaches from the core component to expose a region of adhesive on a part of the web component that extends from the tail end of the web. The tail end thus can be spliced to a leading end of another web by attaching the leading end to the exposed adhesive on the web component.
