ABSTRACT:
The machine of this invention applies successive lengths of tape, such as tear-tape, to a continuously moving products, such as a web about to be die cut for forming boxes. The application of the tapes is registration-correlated with the product. Self-adhesive tape is drawn from a roll by a capstan roll which provides a controlled feed of the tape to an applicator wheel. The applicator wheel draws the tape around the applicator wheel, holding it by suction. When a predetermined length on the applicator wheel has passed a cut-off point, that length is cut off, and then the wheel presses its adhesive face against the moving web. The applicator wheel has the same peripheral speed as the web, but the capstan roll, though rotating with it, is substantially smaller and has a lower peripheral speed. After severance, the cut length accepts the peripheral speed of the applicator wheel so as to be properly applied to the web, but the tape behind the cut is still retarded by the capstan, so that it backslips on the applicator wheel and a gap forms between the two pieces. The drive of the applicator wheel and capstan is through a phase adjusting device for adjustment of the registration of the tape on the web (usually having printing in registration with the blankcutter). The tape is cut by a knife blade passing entirely through it inwardly so as to avoid any tendency to lift the tape from the applicator wheel, and to clear the web.
