<p>A continuous tape supply apparatus is provided in accordance with the present invention for supplying tape at a substantially consistent tension to a tape applicator machine having an indexing demand, such as a box sealing and taping machine. In general, the continuous tape supply apparatus includes plural tape sources, such as in roll form, from which tape can be supplied to the tape applicator machine, a splicing station for splicing the tape from at least one of the tape sources to another of the tape sources, a means for causing the splice and thus the changeover of tape from one source to another, and a tension control means for providing the tape from the continuous tape supply apparatus at a substantially consistent tension under an indexing demand. Preferably, the splicing mechanism also splices tape in the reverse order from the other tape source station back to the first tape source stations. The tension control means is preferably provided by a tape drive station, a first dancer arm providing a variable loop forming means between each of the tape supply sources and the splicing station, and a second dancer arm positioned operatively after the tape drive station which is located operatively after the splicing station. The first dancer arm is further preferably used to control a braking mechanism which together eliminate roll inertia effects to the splicing station. The second dancer arm is also advantageously used to control the speed of the motor drive of the tape drive station.</p> |
