Title: Paying-out appts. drawing off light conductor from supply spool - feeds conductors over brake to processing station via friction wheel to prevent tangling
Inventor: HAMLISCHER WOLFGANG
IPC: B29C48/156
Filed: 1991-05-02
Abstract: Between the brake (1) and the processing station (5) each conductor (3) is assigned to a low friction inertia disc or wheel (4). The assigned conductor is held around the circumference of the wheel by friction. The product of the weight and the inertia radius of the wheel is at least as big as for a solid 250g wheel with a dia. of 20cm. The conductor meets the circumference (11) of the wheel at such an angle as to cause a friction lock which is smaller than the friction force of the conductor and is bigger than 1N. A sensor (21) may be coupled to the wheel to detect the angle of rotation and/or the number of revolutions of the wheel. ADVANTAGE - Conductors fed to processing station simultaneously and without jerking.

Title: Control of percussive forming machines - is based on workpiece thickness with automatic adjustment of impact energy
Inventor: RUEGER HERBERT DIPL ING
IPC: B23Q15/007
Filed: 1991-09-26
Abstract: The control installation of a percussive forming machine, based on the thickness of finished workpieces, has a displacement measuring device (9) in which a stationary distance sensor (11) is aligned against an inclined element (10) mounted on the ram (4). The sensor (11) determines the distance variation between itself and the inclined element. An associated control device (13,14) uses a sign change of this variation to establish the bottom return point of the ram and the corresp. workpiece thickness. The device (13,14) as well as the indicator of set thickness value is connected to an electronic control unit which contains a difference-forming element (15) and a programme memory (18), and operates an impact force adjusting device (17). The distance sensor (11) is pref. eddy current sensor and is mounted on the machine frame. The displacement measuring devices (9) are located on two opposite sides of the ram (4) and the connection of the distance sensors (11) with the control device (13,14) takes place via an addn. element. The installation can include an electronic sampling and storage system for the thickness values after each impact on a reference workpiece. The system also includes a selection and holding unit for using one of these values as a set final thickness. USE/ADVANTAGE - The invention can be used, for example, in forging plants. In comparison with known installations used in this field, its use allows the energy per impact to be better (and completely automatically) adjusted, so that the final workpiece thickness is attained with a min. number of impacts.
