Abstract: PURPOSE:To prevent the shock due to the change in the feed rate of the pressure oil at the point of metal-off of the rolled material, by actuating the timer for a period of time to travel a distance corresponding to the rolling speed during the rolling work, by producing the timing signal for the metal-off of the rolled material, by intercepting the output of the automatic control, and by widening the roll gap depending on the signal for some period of time. CONSTITUTION:The arithmetic circuit 13 operates the distance-timer value (t) from the distance given by the reference value circuit 10 and the rolled material's speed (v) given by the line speed signal generator 11. To this result the correction value of the timer value correction circuit 14 is added, in order to correct the detecting error of detectors 20, 21, respectively for the front end face and the tail end face of the rolled material 1. The time-up detecting circuit 16 detects the time-up, and the metal-off signal generating circuit 17 generates the metal-off signal, and these signals are given to the control system. If the timing detecting circuit 12 detects that the detecting output of the detector 20 becomes OFF, the timer is started at this timing, and the metal-off signal is produced depending on that time-up, and hereby, the metalff of the rolled material 1 is detected independently of the reaction force against the rolling load.

Abstract: PURPOSE:To obtain an entirely glossy molding free from a cavity by providing upper and lower structure. parts which move in a mutually opposite direction in a mechanical frame, then allowing a top force and a bottom force to be united by an exhaust and suction conduit communicating with the cylinder chamber of an upper structure part, and further allowing both forces to communicate with a closed die void. CONSTITUTION:A cavity is closed through a top force 7 and a bottom force 8 fixed to an upper structure part 1 and a lower structure part, and an air is exhausted from the cavity through a suction conduit 10. Consequently, both upper and lower structure parts become closer to each other, resulting in the unity of the top force 7 and the bottom force 8. Further, a vacuum supply into the upper cylinder chamber is suspended after filling the interior of the lower die 8 with a material, and an air is exhausted from the lower cylinder chamber through the suction conduit 10. If the top force 7 comes into contact with a packing 9, an atmospheric air is fed from the upper suction conduit 10, then the top force 7 is pressed against the packing 9 by a lift mechanism 16 to seal the top force 7, and at the same time, the cavity is preliminarily pressurized. After that, a repressurized zone 12 provided on the surroundings is subjected to be exhausted through the suction conduit 10. Thus a total press pressure is created to perform a two-stage pressurization process.
