The invention relates to a method and a device for the manufacture of paint rollers by winding a textile fabric (3) onto a plastic tube (2) along a spiral-shaped line. According to the invention, a number of tube elements (6), having a length suitable for a paint roller, are slipped onto a revolving mandrel (1). The tube elements are clamped together so as to engage one another and so as to allow them to be rotated together with the mandrel (1). The mandrel is rotated at the same time as the fabric is would on and attached to the tube elements, after which the fabric is cut at the joints (8) between the elements. Due to the invention, the cutting can be performed in the same machine without the risk of damaging the mandrel. As the cutting is made through the fabric only, this entails much less knife wear and is less energy-consuming. Preferably, the tube elements have a toothing at their axial ends for mechanical interconnection at the joints between the tube elements and with the mandrel (1). |
