<p>The slipping clutch is for use with the winding roller of a recording machine, having a coil spring acting in the axial direction with adjustable pressure against friction surfaces which can turn in relation to each other. The surfaces are formed by pairs of friction washers (4, 5) working together, one (5) of each having one or more lugs (5a) by which it is coupled to the roller (1), while the other (4) is similarly coupled (4a) to the drive spindle (7). There can be an axial groove (9) formed inside the roller, in which the lugs work, and a further one (8) in the spindle for the same purpose.</p> |
