A slitting machine for threading scrap material includes first and second arbors; rotary knives disposed on each of the first and second arbors; and a pair of notching modules positioned on opposite ends of the first and second arbors. The notching modules each has a pair of shear knives for making multiple cuts in a strip of material passing through the slitting machine forming notches to enable threading of material to scrap chutes from the slitting machine.

The invention relates to a brake device (1) for braking an elongate medium (10) that is to be wound up, having an energy recovery device (16a; 16b; 16c; 16d) which is coupled to the at least one braking roller (14a) and which is designed to act on the at least one braking roller (14a) with a predefined braking moment in order to brake the elongate medium (10) that is to be wound up. The invention furthermore relates to a method for operating a brake device (1) for braking an elongate medium (10) that is to be wound up.

A method for trim loss optimization for metal industries includes receiving a selection of one or more orders for metal trimming. The method also includes inputting the one or more orders and multiple machine parameters to a dimension conversion engine, the dimension conversion engine configured to determine a roll width and a roll length for optimally fulfilling each order using decomposition of a three dimensional problem into a two dimensional problem based on spatial decomposition. The method also includes identifying at least one metal forming or conversion machine for processing the one or more orders. The method also includes inputting one or more metal tolerances as edge trim parameters to a trim algorithm. The method also includes determining, using the trim algorithm, a number of parent rolls for fulfilling the one or more orders using the at least one metal forming or conversion machine.

A winding machine (100; 100a, 100b) for wrapping strands of rolled material, such as a bar, a rod, wire or the like, around a reel into coils: a reel (50; 50a, 50b); a base flange (1) defining a first catching recess (6) intended to receive an end of a first strand (17; 17a, 17b); a first cover (9) movable between an open position leaving the first catching recess (6) exposed and a closed position covering the first catching recess (6) to form a closed passage for the end of the first strand (17; 17a, 17b) in order to secure the end of the first strand to the reel (50; 50a, 50b). At least a second element (2) defining a second catching recess (4); and at least a second cover (8) movable between an open position leaving the further catching recess (4) exposed and a closed position covering the second catching recess (4) to form a closed passage for the end of a second strand (27; 27a, 27b) in order to secure the end of the second strand to the reel (50; 50a, 50b).

Provided is a slitter device capable of quickly supplying metal bands to a cutter stand and cutting same into strips with high speed and accuracy. The metal band slitter device comprises an unwinder that unwinds a metal band wound into a coil, a cutter stand that cuts the unwound metal band into narrow width strips, and a winder that winds the cut metal band into coils. The metal band slitter device is configured to comprise a tension adjustment unit on the winder side between the unwinder and the cutter stand that provides a constant tension to the metal band and a tension separating unit on the cutter stand side that separates the constant tension on the input side and tension on the output side.
