ADHESIVE SPREADING UNIT PROVIDED WITH A ROLLER-CLEANING DEVICE

摘要

An adhesive-spreading assembly includes a plurality of rollers (R), that rotate in contact with one another to transfer a thin layer of adhesive from a tank (T) onto a film in motion, complete with a device for cleaning the rollers (R), removably connectable to the adhesive-spreading assembly and including at least one tank (5, 6) containing at least one cleaning fluid and pumping elements (8) for transferring the fluid to distributor elements (12) for delivering a part of the fluid onto the surface of the rollers (R). The adhesive-spreading assembly includes a transfer system (15) designed to transfer the distributor elements (12) in a direction substantially parallel to the axis of the rollers to distribute the fluid over their whole surface, the transfer system being configured so that it can be removably coupled with the distributor elements.
