  • Patent number: 8096158
    Abstract: The invention relates to an apparatus and a method for cropping the ends of or for separating test pieces from rolled strip wound into bundles. An apparatus is disclosed which, by means of an outwardly pivotable bottom roller (2) and guide devices (5, 6, 7, 8, 13, 14) for guiding the strip end to the shears, also makes it possible to process strips which are thicker or of greater firmness and are wound into bundles (10). Furthermore, a method is specified, which allows a reliable sampling and, if appropriate, inspection of the sample from strips wound into bundles, a closed bundle being obtained again after sampling.

  • Patent number: 6443046
    Abstract: There is described a method of controlling a long-stroke, hydraulic operating cylinder (1), in particular a screw-down cylinder for an edging stand, where the piston (4), to which a load can be applied at both ends, and which can be locked hydraulically along its stroke (s) in various working positions, is abruptly loaded with an external force after it has been locked. To create advantageous method conditions, it is proposed that the piston (4) be locked under a hydraulic pressure chosen in dependence on the respective working position, which hydraulic pressure decreases along the stroke (s) against the direction of action of the external force.
