Tail for attaching trailing edge of one roll of tape to leading edge of another roll of tape

摘要

A tail for adhering the tailing edge of a first roll of tape that is being fed to an application device to the leading edge of a second roll of tape without stopping the tapes includes a bulge which is located in the tail and has an adhesive coating on each side. A first protective element located on the tail releasably covers the adhesive coating on one side of the bulge and a second protective element located on the other side of the bulge releasably covers the adhesive coating on the other side of the bulge when the tail is wrapped onto a roll base. The leading edge of the second roll of tape is wrapped around the tape from the first roll to form a loose knot and then is threaded through a pair of pincher rollers through which the first roll of tape is fed. Thus, when the bulge passes through the pincher rollers it becomes adhesively attached to the leading edge of the second roll and the knot is tightened around the second roll and a mechanical joint is formed between the tapes.
