Abstract: An automatic production and assembly machine focuses on the fact that each unit is provided with coding indicating at least the type of the specific function unit. The coding is transmitted via data transmission existing between the individual function unit and a central control unit. The coding makes possible continuous checking of the control program, such that certain program sequences for certain workstations are only executed when the coding of these workstations agrees with the respective program sequence. A number of other important functions are monitored, corrected and made to coincide with the central programming.

Abstract: An automatic assembly or production machine and workstation for such a machine which has a rotor that is rotatable around a vertical machine access, and has several receptacles on the periphery of the rotor for components or work pieces to be assembled or for subassemblies. The machine has a central drive means for the rotor for moving the receptacles in a cyclic movement from one work position to the next. Each work position has primary functional elements with a common control unit for them driven by a central drive assembly and producing controlled movements of the element in at least one axial direction in synchronization with the cyclic rotary movement of the rotor.

Abstract: The invention relates to an apparatus for the orientated supply of helical springs, which are provided on at least one end with an open loop, to a working station, having a first conveying device, to the end of which are supplied the springs resting with their spring bodies on a support surface of the first conveying device and with their longitudinal extension arranged in the conveying direction of the first conveying device, and having a second conveying device with its beginning adjoining the end of the first conveying device.

Abstract: An apparatus for fitting O-ring onto workpieces employs a spreading tool for spreading an O-ring and a receiver tool for receiving a spread O-ring that operate to transfer the O-ring from the spreading tool to the receiver tool without relative movement between the O-ring and the spreading tool and the receiving tool in the direction perpendicular to the face of the O-ring, whereby overstretching and distortion of the O-ring are both avoided.

Abstract: The invention relates to an apparatus for singling and orienting coiled tension springs which have hook-like bends at, at least one end of the spring. The apparatus uses a guide through which the springs are fed to a receiver. The receiver has a chamber and the chamber has an inlet opening for the introduction of the spring into the chamber of the receiver. The receiver can swing about an axis that is transverse of the axis of the guide from a first position in which the inlet opening of the chamber is in line with the guide and the chamber of the receiver forms the prolongation of the guide to a second position in which the inlet opening of the chamber is out of line with the guide. A sword-like element moves into and out of the chamber in a direction transverse to the chamber.

Abstract: A device is disclosed for forming axial grooves in cylindrical workpieces. The device includes a first tool part having a receiver for the workpiece, and at least one lever pivotably mounted within the first tool part. The lever supports a grooving tool provided with a cutting edge facing the receiver. The lever also has a first bearing or supporting surface on the side opposite the cutting edge, against which one end of a clamping bolt abuts. The clamping bolt is driven by a second tool part rotatably supported on the first tool part so that it can pivot around the receiver axis.
