Abstract
A roll-winding machine for winding rolls of a web material, especially for use in a clean room, has a traverse extending the full operating width and provided with a plurality of slides whose arms hold the rolls to be wound. The slides have legs which pass through slits formed in an enclosure constituted by cover plates and/or the traverse walls so that the enclosure completely surrounds the guide surfaces of the slide feet on the rails of the traverse, leaving free only the minimal slits through which the legs pass. As a consequence, the release of contaminants into the surrounding space is greatly reduced.
