In the field of unwinding webs from an unwind stand in which a fresh web is prepared with a paste strip and is lapped spliced to a progressing expiring web, and the expiring web is then cut upstream of the splice to form a tail, the position of the tail is predicted or detected, and the movement thereof to a taping station causes a tape support roll, which supports a strip of one-sided adhesive tape to be applied to the tail in such a manner that part of the adhesive strip covers the tail and part of the strip engages the underlying web so that the tail becomes firmly taped down to the web thereby permitting the web to be run in either direction through processes such as converting processes, coating processes or the like. Embodiments of tape tail detectors are disclosed and embodiments of hold-down tape transfer mechanisms are disclosed.
In the art of web unwinding in which a fresh web is spliced onto a moving expiring web, and in which a trailing tail of a cut expiring web laps a portion of the fresh web, the method of taping such tail to the fresh web without interrupting the movement of such web, comprising the steps of:
The method of claim 4 further comprising the steps of supporting said strip of adhesive tape on the surface of a tape support roll prior to said determining step, and in which said applying step includes moving said tape support roll with said strip of tape applied thereto relative to said fresh web such that said tape engages said tail at said end thereof in the region of said marker.
In the art of web unwinding in which a fresh web is spliced at a splicing station onto a moving expiring web and in which a cut trailing tail of the expiring web, after splicing, laps a portion of the fresh web, the method of taping such tail to the fresh web without interrupting the movement of the fresh web, comprising the steps of:
Apparatus for taping down the tail of a splice on a progressing web in which a leading edge of the web from a fresh roll is spliced onto an expiring web thereby forming an overlapping splice, and in which a knife severs the expiring web following the splice and forms a trailing tail of the expiring web, which tail extends upstream from the splice in overlapping relation to the fresh web, comprising:
In the art of web unwinding in which a fresh web is spliced onto a moving expiring web, and in which a trailing tail of a cut expiring web laps a portion of the fresh web, the method of taping such tail to the fresh web without interrupting the movement of such web, comprising the steps of:
In the art of web unwinding in which a fresh web is spliced onto a moving expiring web, and in which a trailing tail of a cut expiring web laps a portion of the fresh web, the method of taping such tail to the fresh web without interrupting the movement of such web, comprising the steps of:
