ABSTRACT:
A contact pressure parting device for applying a continuously moving metal strip (1) to a winding reel (2). The contact pressure device comprises a contact pressure element (7) which is disposed on the rear side of the strip (1) remote from the winding reel (2) by which the strip (1) can be forced on to the winding reel (2), which is provided with an adhesive (3). The contact pressure and parting device also has a blade (8) which is disposed downstream of the contact pressure element (7), viewed in the direction of strip travel, and can be advanced against the rear side of the strip (1) and which when its cutting edge (8a) impinges on the strip (1) parts the strip (1), the blade (8) then being swung away from the strip (1) and the winding reel (2). In its starting position the cutting edge (8a) of the blade (8) is disposed upstream, viewed in the direction of strip travel, of the place (P) on the strip (1) situated closest to the pivoting axis (12) of the blade (8). Since as it is being swung away the blade (8) must pass through its zenith in relation to the strip (1), the strip (1) is reliably parted even when the blade is slowly advanced in its direction.
