Abstract

1360935 Bending metal MITSUBISHI JUKOGYO KK 8 Sept 1972 41903/72 Heading B3E The blending of a metal member 1 pushed through fixed pairs of guide rolls 2, 4 and bent by a bending roll 3 is monitored by an arm 5 pivoted to a point 6 fixed on the member and a fixed point 7 and containing a device 8 generating a signal used to detect deviation of the point 6 from a prescribed path, the signal adjusting the force with which roll 3 bears on the member so as to correct such deviation. Further devices at the points 6, 7, measure angles # 1 and # 3 <SP>11</SP>, their outputs being used to indicate attainment of a required angle of bend, or to stop further bending. The apparatus includes an induction heater 13 and cooler 14 at the bending zone.
