<p>The roller for winding on a strip or filament material such as plastic film, paper or textile, has a tubular mandrel (1) with its ends shaped to enable it to be connected to a rotary support, or equipped with flanges (3) so it can be used as a bobbin. The two ends are fitted with discs (2), each having a central aperture (2a) that connects with an inner cavity (1a) and coupling elements for attaching the flanges. These are in the form of holes (2b) with narrow ends shaped to receive and lock lugs (3a) projecting from the inner surfaces of the flanges, the holes and lugs being spaced at regular intervals of e.g. 90 degrees. The central apertures in the discs and inner cavities in the mandrel ends are shaped to receive drive members.</p> |
