Claim:
A method of closing and unclosing a bobbin, said method comprising the following steps: a) providing a closing banding on a bobbin, wherein the closing banding comprises: i) a paper carrier having an upper transverse edge and a lower transverse edge opposite said upper transverse edge, and which is coated with a self-adhesive compound on its underside in the region of the upper transverse edge, but is not coated on its topside with self-adhesive compound, and has a non-adhesive tab in the region of the lower transverse edge; wherein ii) a double-sided adhesive tape is arranged on the underside of the paper carrier, between the self-adhesive compound and the tab, the double-sided adhesive tape having a cleavable paper carrier which is coated on both sides with self-adhesive compound; b) closing the bobbin by fixing an end of an uppermost layer of the bobbin to a second layer located underneath by bonding the closing banding to an end of the uppermost layer of the bobbin by means of the self-adhesive compound in the region of the upper transverse edge of the closing banding, in such a way that the closing banding projects beyond this end, and fixing the closing banding to the second layer of the bobbin by means of the self-adhesive compound on the cleavable paper carrier of the closing banding; and c) unclosing the bobbin by pulling on the projecting tab, causing the cleavable paper carrier to cleave so that an end of the bobbin is liberated, wherein said pulling does not involve splicing the bobbin to another unwinding bobbin.
