CALANDRA PER STAMPARE A RILIEVO SU FOGLIE TERMOPLASTICHE

摘要

An embossing calender for thermoplastics films in which the film is embossed by passage between an embossing roller and a counter-roller and in which the rollers can be rapidly changed or replaced. This is achieved by providing separate support arrangements for the two rollers, which arrangements permit the respective rollers to be displaced into and out of their working positions. The support arrangement for the embossing roller comprises a support member along which at least one holder for the roller is displaceable between a working position and at least one further inoperative position. This permits the selective positioning of each holder and its associated roller. The arrangement for the counter-roller comprises a support which has a pivotally mounted displacement device associated therewith. The displacement device includes holders. The pivotal movement of the displacement device permits the holders to move into and out of contact with the counter-roller so as to move it into and out of its operative position. This permits an appropriately selected counter-roller to be located in the operative position.
