Abstract: Method and apparatus for automatically straightening elongated and at least partly rotationally symmetrical workpieces by applying a sequence of straightening strokes to a workpiece at each of a plurality of straightening stations to counteract a deformation until the measured instantaneous values of the deformation fall within a predetermined deformation tolerance. The depth of the straightening strokes is determined by the difference between the measured instantaneous values of the deformation and the mean of the maximum and minimum values of the deformation.

Abstract: Method and apparatus for automatically straightening elongated and at least partly rotationally symmetrical workpieces by applying a sequence of straightening strokes to a workpiece at one straightening station to counteract a deformation until the measured instantaneous values of the deformation fall within a predetermined deformation tolerance. The depth of the straightening strokes is determined by the difference between the measured instantaneous values of the deformation and the mean of the maximum and minimum values of the deformation.

Abstract: The invention relates to methods for simultaneously producing crimped fibre strips in parallel, in particular filter tow strips, in a crimping machine (KM) having an inlet region (3), a squeezing zone (6) formed between two transport rollers (4, 5), and a compression channel (7), comprising the following steps: a) simultaneously feeding in parallel a plurality of fibre strips (1, 2) via the inlet region (3), wherein the fibre strips are guided separately in the inlet region (3), using a first separating device (31), b) simultaneously transporting and compacting in parallel the fibre strips in the squeezing zone (6) by way of the two transport rollers (4, 5), and c) simultaneously crimping in parallel the fibre strips in the compression channel (7), wherein the fibre strips are guided separately in method step b) by using a second separating device (61) and in method step c) by using a third separating device (71), and wherein the first, second and third separating devices (31, 61, 71) are designed such that the separate guidance in parallel of the fibre strips takes place from the inlet region (3) through the squeezing zone (6) into the compression channel (7) without interruption. Moreover, the invention relates to an apparatus for executing said method. The invention enables the simultaneous formation of a plurality of separate, crimped fibre strips, having a substantially constant and symmetric crimping characteristic over the respective entire fibre strip cross-section, and in particular also cost-effective production of crimped filter tow strips, having a low overall titer, by avoiding the phenomenon of the split-off edge, by way of a conventional spinning and crimping machine.
