Abstract: In a method for producing, from a cast or forged blank, a connecting rod intended for a reciprocating-piston engine and having one little and one big connecting-rod eye, the big connecting-rod eye is split, in a pre-machining step, along a parting plane running through the axis of the eye, the place side faces of the blank being ground beforehand in a first clamping station. After the plane faces of the blank have been ground, first the contour of the big connecting-rod eye and then the split in the parting plane are produced by laser cutting while the blank is held in a second clamping station.

Abstract: To regulate the wire tension, a wire tension regulator is disposed on a winding device for electrical coils. A return roller and a contact roller can be mounted on the regulator for prebraking of the winding wire. The winding wire is subsequently wrapped 360.degree. around a wheel brake. The wheel brake is driven in the forward and backward directions of the wire by a d.c. motor. A strain gauge is disposed between the brake wheel and the winding device. The d.c. motor generates a signal indicating a rotor position to a motor control unit which transmits the position as an amplified signal to a control device and, as a derived set value wire tension signal which also reaches the control device. In addition, a set value wire tension signal of a machine control unit or a set value wire tension signal of a wire tension preset is provided to the control device. The set value of the wire tension is compared with a signal representing the instantaneous wire tension.

Abstract: A multiple coiling machine for winding electrical coils with different coil wires and different coil wire gauges . A wire guide head is pivotally mounted on a support and has at least two wire guides offset from each other. The wire guide head is pivotable so that one of the wire guides is in a winding position and the other wire guide is in a stand-by position. Two clamps are positioned on the head adjacent the pivot axis of the wire guide head. The wire guide head has a slit in the shape of an arc through which a pair of reversing pins is disposed at a distance from each other on the support. Two clamps and two wire guides are provided on opposite sides of the arc. The coil wire is guided around the reversing pin and can be pulled back into the appropriate wire guide by means of the clamp which is pivotable into the stand-by position. The wire guide head is mounted in a bore of the support by means of a pin, so that it is pivotable. A pair of stop faces limit the pivoting movement of the wire guide head.

Abstract: A work piece carrier which has a base plate adapted for frictionally engaging a conveyor belt is disclosed. At least two semicircular supports, open at the top, are rigidly connected with the base and are disposed at a distance to each other. A retaining pin for coil wire remnants is disposed between the two supports of the work piece carrier. A removable auxiliary carrier with a coil body is seated in or removed from each support crosswise to the longitudinal extension of the conveyor belt, where a cylindrical body of the auxiliary carrier has at least one, preferably two auxiliary retaining pins for coil wire ends. In one embodiment, reversing pins are axially disposed at a distance from each auxiliary retaining pin on the cylindrical body of the auxiliary carrier for forming loops of the coil wire. In this way the length of the wire end sections can be varied, for example for subsequent manually performed finishing of the completed coil.

Abstract: An insulating apparatus for the application of a nonadhesive insulating tape (15) to the winding of an electric coil (8) comprises a first pressure head (2) for receiving an adhesive tape (9) and the non-adhesive insulating tape (15). In an alternative embodiment, a second pressure head (18) is located above the first pressure head (2) and faces the latter; both pressure heads being displaceable from a rest position into a working position. The adhesive tape (9) is fed from a supply roll (10) over a stress relief device (11) and the nonadhesive insulating tape (15) is fed from another supply roll (16), with both tapes (9, 15) being held by suction on a support surface of the corresponding pressure head (2 or 18). Each pressure head (2, 18) is equipped with a blade (3 and 4) for the cutting of the tapes (9 and 15). In the alternative embodiment, after the adhesive tape is bonded to the coil, it draws the insulating tape onto the coil, so that the insulating tape is being wound together with the adhesive tape.

Abstract: A multiple spindle winding machine includes a conveyor belt for advancing a plurality of workpiece carriers frictionally engaged thereto to a winding station and a processing station. Each workpiece carrier includes at least two spaced apart coil holding fixtures rigidly secured to a base plate and cooperable with the winding station. A lifting device having guide rails laterally displaced from the conveyor elevates one of the workpiece carriers from the conveyor belt to the winding station. The winding station includes a wire guide and a cutting device mounted to a pivotable arm for providing wire to be wound around a coil. Wire residue is collected by a holding pin positioned on the workpiece carrier.

Abstract: To improve the twisting of wire ends on a coil form having contact pins axially located with respect to a winding shaft, a swivel shaft is provided on each coil holder of a coiler tool. One end of the swivel shaft is in the form of a driving pin and the other in the shape of a fork. The fork shaped end of the swivel shaft is capable of engaging a driving pin located on a rotating drive shaft. The coil holder is in the form of a strap and tiltable. The wire ends are cut by a wire cutting device that is displaceable vertically with respect to a wire guide. The contact pins with the wire ends twisted on them in a parallel manner may serve simultaneously as plug-in pins for printed circuits.

Abstract: The automatic winding of extremely small electrical core coils, for example video core coils, takes place on a rotatable winding unit which cooperates with a wire drawing apparatus provided with a catch hook. Each coil former receiver is provided with an associated wire mount. During the winding, the coil former together with the coil former receiver is immobile wherein the wire section of the winding wire necessary for each core coil is drawn from a wire storage coil over a wire deflector. During the winding of the core coil the rotatable winding unit, together with a plurality of wire retainers arranged in a vertically adjustable winding head, can be positioned so that the catch hook passes horizontally not only through one of the wire retainers but also through the core opening in the coil former. After applying the winding wire to one limb of the coil former during the withdrawal of the catch hook through the core opening, the cyclic rotation of the wire retainers then takes place through 270.degree.

Abstract: The present invention relates to a plug-in arrangement for circuit boards and a process for tin plating contact pins of the arrangement. The present invention improves the tinning of winding end portions of a winding about nonmetallic contact pins on coil forms. The contact pins are adapted for connection with printed circuits. The present invention discloses contact pins in one piece, or with multiple parts, which pins are given a profiled configuration on an outer surface. The contact pins may have different profiled shapes or configurations including grooves. In the case of multiple part contact pins, gaps are provided between the parts. The grooves or gaps permit the escape of gas generated upon the burning of an enamel insulation layer on the winding end portions. Also, the end portions rest above bottoms of the grooves or gaps such that the end portions are surrounded with tin solder.
