Abstract: For shaping longitudinal grooves or comparable longitudinal structures into round housings or housings which are otherwise regularly shaped with respect to a longitudinal axis, a press is provided with a deforming tool whose top tool presses a workpiece through a corresponding roll arrangement of a bottom tool. The bottom tool has an opening which is coaxial to the top tool contains an axially displaceable cage provided with a group of rolls. The rolls are rotatably disposed in the cage and are supported on radially exterior abutments which are stationarily held in the bottom tool. The rolls are constructed as profile rolls and shape the desired longitudinal structures into the workpiece when it is moved through between the profile rolls. The resulting radial reaction forces are absorbed exclusively by the abutments and not by the cage. For supporting the longitudinal movement of the cage, a transmission is formed, for example, by gear wheels which are rotatably disposed on the cage.

A monitoring element is provided, which checks to ensure that the connecting pin is fully inserted. The monitoring element is connected to the power source of the drive motor by means of a switching element.

Abstract: For tying a compressed bale tending to expand primarily along a major axis, a bale tie made preferably from steel wire or alternatively from steel strap is bent to form two marcelled portions, which are characterized by sinusoidal undulations, which are oriented so as to be generally parallel to the major axis, and along which the tie can straighten to absorb tensile forces. A joint is formed at the opposite ends of the tie. Where bent to form the marcelled portions, the tie has an ultimate strength less than the ultimate strength of an undeformed portion of the tie but more than the ultimate strength of the joint. An apparatus for forming a wire with a marcelled portion comprises upper rolls and lower rolls, which are rotatably mounted and respectively on an upper block and a lower block. The upper block is pivotally mounted upon the lower block.

Abstract: A method for making blanks of a profile varying lengthwise, such as few-leaf springs involves placing a heated billet (1) on a sizing former (2) and feeding it to a deformation zone for forming a product of a preset profile which is carried out from the middle part (3) of the billet simultaneously towards its ends (4,5) thereof to form its runs by drawing or rolling. In an apparatus for carrying out this method, a forming means is provided with a constant-size groove (6) so that the billet runs are formed simultaneously during passage therethrough, or has a pair of carriages supporting non-driven rolls and moving in the opposite directions.

Abstract: A rod bending device using a combination of a movable mandrel and two moving rollers, between which mandrel and which rollers the rod bending is effected, the movements of which mandrel and rollers are effected simultaneously by the same power system and by a single power stroke. The power system, preferably a hydraulic system, effects movement of the movable mandrel which in turn simultaneously effects movement of two arms which support the movable rollers. This simultaneous movement of the mandrel and the rollers effects the bending of the rod which is positioned between the mandrel and the rollers. The curvature and the degree of the bending are determined by the shape of the mandrel, the positioning of the rollers on the supporting arms and the extent of the revolution of the arms about the individual fulcrums on which the respective arms are revolved.
