Abstract
Disclosed is a method for joining two strips, where the two strips each include a laminate of a release liner and a pressure-sensitive adhesive layer, and the release liner extends from the corresponding pressure-sensitive adhesive layer in a longitudinal end region of at least one of the two strips. The method includes butting cross-sections of longitudinal ends of the pressure-sensitive adhesive layers of the two strips to bond the two pressure-sensitive adhesive layers; and superposing end regions of the release liners of the two strips and fixing the release liners so that surfaces of the release liners in portions at least 1 mm long inward from the longitudinal ends are not in contact with surfaces of the pressure-sensitive adhesive layers. This method gives a continuous strip from which the release liner can be smoothly removed without 'binding' even at the joint.
