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.

The invention relates to a light type rapid splicing warm box. The light type rapid splicing warm box comprises six face heat preservation plates, four box cover wrapping corners, four box opening wrapping corners, four box bottom wrapping corners, four box cover side strips, four box opening side strips, four vertical side strips and four box bottom side strips; the four box cover side strips, the four box cover wrapping corners and the top face heat preservation plate form a box cover; the four box bottom side strips and the four box bottom wrapping corners form a box bottom ring frame, the four side face heat preservation plates are inserted in four box bottom inserting grooves of the box bottom ring frame correspondingly, the bottom face heat preservation plate is flatly placed on the protruding portion of the top face of the box bottom ring frame, and the four vertical side strips wrap four external corners formed by the four side face heat preservation plates correspondingly; the four box opening side strips and the four box opening wrapping corners form a box opening ring frame, the tops of the four side face heat preservation plates are located in the four box opening inserting grooves in the box opening ring frame correspondingly, and a vertical seal inserting groove used for filing of a seal strip is formed in the top face of the box opening ring frame; the warm box is small in weight, and the needed heat preservation plates do not need to be slotted.
