Abstract: A method for forming a container half (10) from a coated steel sheet (21) is provided. Because a first planar part (27) at an outer peripheral part of a first formed body (26) provided through a first drawing step is held by a blank holder (33) during its bending to provide an L-shaped cross-section part (36) in a second drawing step, no wrinkles will develop at a vertical part (38). Because an unnecessary outer part (44) of a flange part (46) is cut off in a trimming step, the width of the flange part is narrowed. By virtue of the narrowed width, no wrinkles will develop during bending of the flange part.

Abstract: A hemming machine is provided with a frame, a hemming tool support structure and a swinging drive structure. The hemming tool support structure is rotatably coupled to the frame to rotate about a center rotation axis. The hemming tool support structure includes a hemming tool disposed at a first location such that the hemming tool moves towards and away from an edge part of a workpiece that is supported on a die upon rotation of the hemming tool support structure. The swinging drive structure transmits a rotational driving force to the hemming tool support structure via a releasable connection located on a side of the center rotation axis that is opposite of the hemming tool. The releasable connection is configured to release the swinging drive structure to allow further rotational movement of the hemming tool away from the die.

Abstract: A wire strapping or tying device (46) is provided having a rotatable pinion-type knotter assembly (56) for twist-knotting of a pair of adjacent wire sections (50a, 50b), together with a shiftable knotter cover (266) movable between a home position for maintaining the sections (50a, 50b) within the assembly (56) and a remote knotter access position allowing ready access to the knotter assembly (56). The cover (266) is supported by arms (268, 270) which are pivotal about an axis spaced from and generally parallel with the cover (266). The cover (266) may be manually shifted to the remote knotter access position through an arc of at least 45°. Also, the knotter assembly (56) includes a primary body (128) supporting a rotatable, slotted knotter pinion (178). The body (128) is pivotally secured to frame plates (68, 70), allowing the body (128) to be pivoted to a convenient position for servicing of pinion (178).

Abstract: The invention relates to a method for the production of a rolled edge from an edge section (11) of a tube, wherein a flanging die is driven onto the edge section and flanges it into a roll. According to the invention, an initial area (14) of the edge section (11) is previously rolled in a positive fit manner by means of a forcibly controlled tool (30). This prevents buckling of the initial area (14), which has a controlled geometry as a result of rolling. The novel method is preferably used in the production of valve seats in so-called aerosol domes (10) for spray cans.

Abstract: A method for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel which is adjusted in diameter. At the beginning, the inner windings of the coil are coiled on the adjusted coiler mandrel diameter and, after the final winding of the coil, the coiler mandrel is pulled out or the coil is taken off. At least the first inner winding is joined over a large area with the second inner winding by introducing adhesives, fillers, pieces of metal, bonding agents, or the like into an angular space between the inner windings.

Abstract: A method and associated apparatus designed to effectively twist and cut baling wire during the baling process. The apparatus includes a twister assembly that has a plurality of gear-driven twister heads. During the baling process the twister assembly extends from a slide housing so that the twister heads engage and twist adjacent strands of baling wire. The twister assembly then retracts back into the slide housing so that the twisted portion of the baling wire is cut by a cutting assembly attached to the slide housing.

Abstract: A chain link for a conveying chain of a machine of the tobacco-processing industry, in particular a storage device for a rod-shaped tobacco product, includes holding means for a hinge pin and a hinge pin bearing for connecting the chain link to adjacent chain links, and a carrying surface for carrying a tobacco product, which carrying surface is arranged substantially parallel to the hinge plane defined by the hinge axes. The chain link is designed laterally for cooperation with a deflection plate of the machine which rotates about a substantially vertical axis. During cooperation with the deflection plate the chain link is designed to pivot about a longitudinal pivot axis parallel to the longitudinal axis. The chain link has a guide element which cooperates with the deflection plate and which is designed in such a way that a pivot movement of the chain link about the longitudinal pivot axis is counteracted by a frictional force exerted by the deflection plate on the guide element.

Abstract: A device for punching, stamping and/or shaping flat elements (29) includes a base body (1) with a table (18) and support (26) for the flat element (29), and a base plate (17), which supports a punch (24), and which is advanced with a drive (4,5) toward the support (26) and into a working station (II), bringing the punch (24) into contact with the support (26). A large number of successive, very short, highly precise, punching strokes make punched holes or stampings. Short stop periods and short clock times are used for fast moving flat elements (29). Transfer apparatus (9, 7; 35; 43; 46) coupled between the drive (4,5) and the base plate (17) move the base plate (17) without building up pressure from a position of rest (I) The punch (24) is not in contact with the support (26), up to immediately in front of working position (II). The base plate (17) is then moved into working position (II) while producing a high pressure between the base plate (17) and the flat element (29).

Abstract: A cooling fan 17 is arranged on the rear side of a twisting motor 9 of a reinforcing bar binder 1. The cooling fan is located on the axial line of the twisting motor so that cooling air effectively flows along the surface of the twisting motor and through within the twisting motor. A control unit on-off controls the cooling fan according to the temperature detected by a heat sensitive element 23 so as to actuate the cooling fan when a trigger signal is received at an interior temperature not lower than a reference value and to stop it after a predetermined time elapses. Thus, the temperature of the reinforcing bar binder can be controlled within a safe temperature range. Even if the reinforcing bar binder is run during a long time, a protecting circuit is not operated to forcibly stop the reinforcing bar binder. Further, in a cold environment, the cooling fan is not actuated so that the performance at a low temperature is not deteriorated and so power consumption can be also saved.
