    摘要: A splicing head for an automatic zero-speed web splicing machine is disclosed in which the end of a new roll of web material can be prepared for splicing directly on resilient nip rollers which are used by the machine to perform the splicing operation. In particular, the splicing head includes a knife carriage through which the web material passes and which can be moved transversely to the web travel direction under control of a cam and lever arrangement to introduce a predetermined loop of slack into the web material.The action of the cam and lever mechanism also positions a serrated preparation blade mounted on cantilever arms in front of the nip rollers for squarely trimming the edge of the web material. After the web material has been trimmed the preparation blade can be moved by the cam and lever arrangement to an out-of-the-way position to allow preparation of the web material and to prevent interference with the splicing machine as the web material runs through the machine after the splice has been made.
