Abstract: A method for producing a structured sheet-metal strip includes feeding a smooth sheet-metal strip to a shaping apparatus along a guiding direction. A primary structure is produced in the smooth sheet-metal strip through the use of the shaping apparatus, during which a number of separate shaping tools act upon the sheet-metal strip in a manner that is substantially perpendicular to the guiding direction. An apparatus for producing a structured sheet-metal strip can produce the structured sheet-metal strips with a particularly low ratio of corrugation length to corrugation height. Such structured sheet-metal strips are used, in particular, for producing purification components in mobile exhaust gas systems.

Abstract: A method and apparatus for selectively predicting the air flows from a duct system that would be produced by environment conditioning plants. The apparatus includes a measurement duct connected to a blower. A restrictor plate is movably mounted over an inlet to the blower to vary the air flow produced by the blower so as to correspond to the air flow generated by a selected environment conditioning plant. A manometer is connected to the measurement duct and is operable to measure static pressure in the measurement duct when the measurement duct is in air flow communication with the duct system. Performance curves for the environment conditioning plants are used to convert static pressures to air flows.

Abstract: Procedure and apparatus for the optimized manufacture of coil springs on automatic spring winding machines. It is the object of the present invention to offer both a procedure and an apparatus by which even in case of fluctuating values of the wire parameters high accuracies during the spring manufacture are guaranteed and simultaneously the scrap is minimized. The solution to this problem is that prior to the winding the wire parameters are determined and the measuring results are used directly for the adjustment of the position of the winding pins or winding rollers and/or the pitch wedge, and that the wire between the uncoiling device and the guiding assembly forms a loop whereby the lateral deflection of this wire loop is measured by a recognition unit and the uncoiling device carries out an additional movement controlled by the recognition unit.

The faces of the steel tape each include substantially rectalinear ribs arranged in at least one longitudinal row, the ribs being substantially parallel to each other and inclined with respect to the longitudinal direction of the tape. The ribs of one of the faces of the tape are symmetrical with respect to the ribs of the other of the faces of the tape in relation to the plane of the tape, parallel to the faces of the tape.

Abstract: A planetary mill having two stationary backing bodies, located one above the other in chocks in a roll stand. Two synchronously rotary-driven cage rings are coaxially mounted on the backing bodies so as to be separated from one another. The case rings rotate in parallel planes of rotation, and respectively hold, in swing roll bearings, one end of work rolls and/or intermediate rolls arranged between the two cage rings. The rolls and the cage rings rotate together around the backing body. The rolls rest against roll-off surfaces in the area of the roll gap. The cage rings are turnable relative to one another in their planes of rotation, to permit setting of the desired rolling material profile without changing the position of the roll-off surfaces.

Abstract: A tool ring (1) for securing blanks in a machine of the type comprising a pair of rotating rings whose opposite, plane side faces are formed with a plurality of holding tools (8, 11) so adapted that an oblong blank (16) can be secured substantially radially between a pair of holding tools in respective ones of said rings. At least one ring has a groove (4) which is adapted to receive holding tools and spacer tools (9, 10, 10', 12) of which at least the holding tools have a convex face (23, 33) to engage the engagement face (19) of said groove. The holding tools (8, 9, 11) are mutually spaced by the spacer tools, and some of the spacer tools (10, 12) are positioned in the groove, while the position of the spacer tools is defined by the cooperation between edge faces (24, 25, 30, 31) on the tools.

Abstract: A machine for transforming zigzag wire to the slotted tubular form ready for use as a binding element comprises means for feeding a strip of zigzag wire longitudinally, means for arresting the feed of each prong of the wire strip as it reaches a shaping station, means for clamping each prong at that station and means at the station for shaping each clamped prong. The shaping means comprises two or more forming tools mounted on rollers which are driven by drive shafts, at least one roller being angularly adjustable relative to its drive shaft. This allows the operation of the forming tools to be synchronized so that symmetrical shaping of the zigzag wire is achieved. The feed means are rotary and means are provided whereby the feed of each prong is arrested for at least one eighth of each revolution of the rotary feed means. The shaping of the zigzag strip is facilitated and improved since the strip is held stationary for a relatively long period of time.

Abstract: Two rolls are supported laterally in bearings in two pairs of side-by-side members with the members being supported by a frame. Adjustment of synchronization and registration is accomplished by adjusting the relative positions of the side-by-side members in or against the rolling direction. The relative positions of the rolls can be adjusted by use of notches engraved in the ends of the rolls; and can be continuously monitored with the aid of a stroboscope light. Magnetic signal devices and other sensors are also suitable for monitoring. Continuous adjustment of roll position is accomplished through low-pitch screws or through hydraulic or electric positioning motors.
