Abstract
A device for the crimping of synthetic yarns, bundles or bands, which includes a pair of pressure rollers and a subsequent stuffer box chamber having two plates, arranged parallel to the axes of the rollers, of which one is mounted at least partially movable for reducing the chamber area, and two lateral walls, closing off the chamber to a nip of the pressure rollers. At the level of the nip of the pressure rollers and in each case positioned adjacent to the edge area of the end surface of a rollers, a pressure disk is provided onto. An adjustment unit which is connected to at least one sensing device, which holds, through the adjustment unit, the pressure disk against the end surface of the roller under a pressure force. The sensing device is constructed as an instrument for determining the bending, adjusted on the basis of the pressure force, of a carrier for the pressure disk and the pressure force is adjustable in dependence on the continuously determined bending of the carrier.
