Claims
- 1. A method for applying a liner/tab strip onto a transversely moving web comprising the steps of:
- longitudinally advancing a web having pressure sensitive adhesive on a first side thereof;
- providing a supply of liner/tab strip;
- advancing the liner/tab strip from the supply laterally across the longitudinally advancing web adjacent the first, adhesive bearing side thereof;
- cutting the liner/tab strip to a length approximating the lateral width of the web;
- urging a leading lateral edge portion of the cut liner/tab strip against the first adhesive bearing side of the advancing web to cause its adherence thereto; and
- urging the remainder of the cut liner/tab strip against the advancing web as the web carries the liner/tab strip away longitudinally.
- 2. The method of claim 1, and further comprising:
- periodically repeating the advancing, cutting and both urging steps as the web is advanced past the supply of liner/tab strip.
- 3. An apparatus for applying a laterally disposed liner/tab strip to an adhesive-bearing side of a longitudinally moving web comprises:
- a supply of liner/tab material;
- a cutter for the liner/tab material;
- a roller drive for advancing the liner/tab material to the cutter;
- a conveyor for advancing a cut section of the liner/tab material severed by the cutter from the cutter to a position aligned laterally across the longitudinally moving web and spaced from its adhesive-bearing side; and
- means for sequentially urging a lateral edge portion and then the remainder of the cut section of the liner/tab material against the adhesive-bearing side of the longitudinally moving web.
- 4. The apparatus of claim 3 wherein the conveyer is a pair of opposed endless belts adapted to advance the cut section of the liner/tab material therebetween, with the belts being laterally disposed adjacent the longitudinally advancing web.
- 5. The apparatus of claim 3 wherein the lateral leading edge portion of the cut section of the liner/tab material is exposed along the conveyor, and wherein the urging means includes:
- a mechanism for moving the conveyor toward the longitudinally moving web until the lateral leading edge portion engages the adhesive-bearing side of the web.
- 6. The apparatus of claim 5 wherein the urging means includes:
- a lay-on roller for engaging the leading lateral edge portion of the cut section of the liner/tab material as it is urged against longitudinally advancing web material.
