Claims20
In a system for cutting with a tape a travelling web of paper being wound on a first spool and transferring that travelling web onto an empty spool by attaching said cutting tape to said empty spool, said cutting tape travelling via a guideway with an elongated slot facing upwardly underneath said web and exiting from said guideway beyond the edge of the web;
- the improvement which comprises an adhesive without any covering thereon applied to one surface of said tape at its forward end before entering said guideway.
An improved method for cutting a travelling web of paper being wound on a spool and transferring the web after cutting to an empty spool, the method including feeding a cutting tape into an elongated guideway positioned beneath and extending laterally across the web of paper, recovering the tape from the far end of the guideway and introducing it into the nip of the empty spool and the roller driving that spool to cause the tape automatically to spirally wrap around the empty spool while cutting the web of paper;
- wherein the improvement comprises the steps of:
- (1) applying adhesive without any-covering thereon to a portion of the cutting tape at its forward end prior to feeding the cutting tape into the guideway;
- and
- (2) receiving the cutting tape exiting the guideway and feeding the forward end into the nip with the adhesive portion contacting the empty spool.
