Abstract: An installation for producing girders for building or the like uses a pair of clamping and bending units to clamp and bend strip material in incremental steps to provide shaped strip with a castellated profile used as a web. The pre-shaped strip material used as the web is then welded to further strip material which forms a longitudinal flange of the girder.

Abstract: Method and an apparatus for binding coils, for example, of sheet steel, which enable the whole process, from the formation of the coils to the completion of the ready-to-be-shipped bound coils, to be automated. Provision is made so that the strips, produced in a slitting line for example, in each case are coiled in coaxially aligned groups and, while their free severed ends in each case are held down, they are collected. Each collected group of coils, while retaining the coaxial alignment and the holding down of the severed ends, are moved into a transfer position, from which the coils, while the respective severed end continues to be held down, are isolated cyclically and transferred into an operating cycle passing through a first and a second binding position as well as a removal position, one or several additional groups of coils being collected while the coils are being worked off cyclically.

Abstract: Apparatus for comminuting scrap in ribbon or strip form from, for example, steel plate into short sections attains a reduced-noise comminuting arrangement of simple construction, and also processes materials of different thicknesses without any readjustment, the apparatus having with two rotors which are driven synchronously in opposite directions and each having knives which project at the periphery of the rotors and which, when they met, carry out a shearing cut, and moreover with two mutually meshing toothed wheels for driving the knife rotors mounted on shafts so that they cannot twist and with a fixed distance between axes, one of the toothed wheels being seated on the shaft of the first rotor and driving this shaft while the other is freely rotatably mounted on the shaft belonging to the second rotor and drives this shaft over a driving mechanism elastically supported in the direction of rotation.
