Abstract
A continuous splicer includes first and second closely spaced rotating cylinders each having a respective cutting element and tape retaining arrangement disposed on its outer periphery. With a depleting web fed by the first cylinder and a replenishing web fed by the second cylinder, an end of the replenishing web is adhesively joined to the depleting web while in motion and the depleting web is severed by the first cylinder's cutting element in forming a splice of the two webs. As the replenishing web depletes, a third web may be inserted on the first cylinder and automatically or manually spliced to the original replenishing web without stopping or re-configuring the splicer. The splicer is capable of delivering the webs at a constant rate or a rapidly changing and/or dynamic cycling rate, and applies relatively low web tension for operation with delicate, narrow and extensible webs.
