Abstract: The invention relates to double trimming shears having a stationary bottom knife and a driven top knife which can be raised and lowered, wherein the top knife is arranged on a top knife carriage (12) guided by means of a carriage guide (10), wherein a first eccentric shaft (14) and a second eccentric shaft (16) on the carriage guide (10) is provided in order to guide the carriage guide (10) if an inclined position of the top knife carriage is to be prevented. This is achieved in that the first eccentric shaft (14) and the second eccentric shaft (16) are interconnected via a synchronization means (18).

Abstract: The present invention relates to a device (1) for removing a sample (24) from a coil (2), comprising at least one bottom roll unit (30, 32) for supporting the coil (2) during removal of the samples, at least one contact roll unit (40, 42) pressable against an outer surface of the coil (2), and at least one strip binding device for binding the coil (2) supported on the at least one bottom roll unit (30, 32). The present invention further relates to a device for removing a sample (24) from a coil (2), comprising a deflection device (70) for deflecting a material beginning (20) of the coil (2) from a beneath located layer (22), wherein the deflection device is so formed that the strip beginning only elastically deflected from the beneath layer (22). The invention also relates to corresponding methods.

Abstract: With known trimming shears having a pair of scrap-cutting blades on the discharge side, the moving upper scrap-cutting blade must be moved as closely as possible past the trimmed plate edge in order to push the cutoff edge still hanging on the plate downward against the lower fixed scrap-cutting blade, which requires precise adjustment of the upper scrap-cutting blade. To that end, according to the invention, the distance between the upper scrap-cutting blade (2) or the lower scrap-cutting blade (3) and the trimming blade plane (5) is set prior to trimming in accordance with the thickness of each heavy plate (10) to be trimmed by displacement of the upper scrap-cutting blade (2) and/or the lower scrap-cutting blade (3) in a displacement direction with at least one component transverse to the trimming blade plane (5).

Abstract: The invention relates to a guide device (1000) for a blade (322) having a slide (320) for receiving the blade (322) and a slide guide (330) and a glide element 300 between the slide guide (330) and the slide (320). A cooling device (205) is arranged for cooling the glide element (300). According to the invention, the cooling device (205) is designed as at least a closed cooling channel (210) or as an open cooling channel (209) having at least one inlet (215, 216) and one outlet (215, 216) for a cooling medium.

Abstract: A hold-down device for plate shears configured to, be pressed down onto a plate to be cut by a mechanically controlled, non-variable displacement. A hold-down device, which can be altered in terms of the pressing force and consequently permits a longer edge life and shorter displacements, and in turn lower indexing times. The starting position of the hold-down device is set before the beginning of the displacement.

Abstract: A deflection for deflecting a strip in a reeling plant, in particular, of a metal strip from an initial channel to a final channel arranged above the initial channel and vice versa, wherein a drive acts with an upper drive roller on the upper side and with a lower drive roller on the lower side of the strip, can be improved when a temporarily pivotable into a strip, upper separating device is arranged downstream of the upper drive roller, and a temporarily pivotable into a strip, lower separating device is arranged downstream of the lower drive roller.

Abstract: The invention relates to a damper construction (2) of a furnace coiler (1) which can especially be used in Steckel mills (1). A hot rolled strip is respectively coiled onto, and uncoiled off, a drum inside the furnace in a reversing manner, by means of a back and forth transport movement, and is optionally heated. Guiding flaps (6, 6?) are mounted on the displaceable damper (2) of the furnace coiler, for inserting and guiding the rolled strip. In order to improve maintenance work, the dampers (2) and the furnace coiler (1) are embodied as separate components. The dampers (2) are arranged on an element (4?) pertaining to a displaceable roller rack (4), said element being located beneath the furnace coiler (1). Each damper (2) is divided into at least two elements (2?, 2?) which can be hinged together, the two hinged elements being connected by means of a hinge bearing (7) in a pivoting manner.
