<p>The radially outermost layer (2) includes an adhesive-free zone (3). This forms a pocket (4) around part of the tubular core (1). Into a opening (5) in the outer layer (2), a free end (9) of the wound material (6) is inserted. In the adhesive-free- or pocket region, a self-adhesive provision is made. The adhesive-free region is circular around the core axis (7) and below the inner surface (8) of the outermost layer. The adhesive- free zone spirals around the core. It is at least slightly wider than the free end. On the outermost surface of the outermost layer, a marking denotes the opening (5), which is a straight, curved or V-shaped slot. The opening has a closed periphery, being especially circular or round. The tubular core is made by separating it from a length.</p> |
