ABSTRACT:
Spool changing apparatus for alternately pulling web-shaped packaging material from two supply spools and feeding the material sequentially to a pair of engraving rollers, a pair of conveying rollers, and a cutting device along a conveying track. An auxiliary device is provided to separate the embossing rollers as a new supply of packaging material is fed therethrough. The material is thus initially conveyed without embossing, thereby avoiding coiling of the new length of packaging material at the outlet side of the embossing rollers.
