PCT No. PCT/EP94/03528 Sec. 371 Date Oct. 25, 1996 Sec. 102(e) Date Oct. 25, 1996 PCT Filed Oct. 27, 1994 PCT Pub. No. WO95/29115 PCT Pub. Date Nov. 2, 1995A splicing tape (200) comprises a splicing portion (1,2) and an attachment portion (42,48), said attachment portion (42,48) being provided for releasably and self-supportively attaching said splicing tape (200) substantially across the width of a roll of sheet material. A first adhesive layer (2) is provided on a backing (1) extending from one longitudinal edge of the backing (1) across the tape to a first position towards the center of the backing (1), said first adhesive layer (2) being provided for attaching the leading edge of the roll to the splicing tape (200). A second adhesive layer (2) is provided on the backing (1) beginning at or beyond, but not overlapping the first position and extending towards the second longitudinal edge of the backing (1). The second adhesive layer is for attachment to a further sheet material. The attachment portion (42,48) includes a third adhesive layer adapted to release the leading edge and splicing portion (1,2) from the underlying sheet material leaving a non-tacky outer surface of the underlying sheet material. The splice can be completed by attaching a further sheet material to the splicing portion (1,2). The third adhesive layer may be provided by a weakly adhering or stretch release adhesive layer. The invention may be adapted to produce overlap, in particular staggered overlap splices. According to the invention, methods of making permanent or flying splices are provided. |
