<p>An apparatus is shown for severing profile pieces of an extruded profile strand ( 1 ) moved in its longitudinal extension, comprising a carriage ( 3 ) which is movable along the profile strand ( 1 ) and comprises a severing device with a saw blade ( 7 ) and at least two clamping jaws ( 5, 6 ) for holding in a non-displaceable manner the carriage ( 3 ) on the profile strand ( 1 ), and comprising a control device ( 13 ) connected with the clamping jaws ( 5, 6 ) and the severing device, which control device triggers the clamping jaws ( 5, 6 ) and the severing device depending on a predetermined length of the profile piece. In order to provide advantageous constructional conditions it is proposed that the severing device is associated with a knife ( 8 ) which can be moved transversally to the longitudinal extension of the profile strand ( 1 ), and that the control device ( 13 ) comprises a selector circuit ( 16 ) for optionally severing a profile piece with the saw blade ( 7 ) or the knife ( 8 ).</p> |
