Abstract

1,248,554. Machinery safety devices. PLASTUND ELASTVERARBEITUNGSMASCHINEN - KOMBINAT KARL - MARZ - STADT VEB. 25 Feb., 1970, No. 9159/70. Heading F2J. In a machine such as an injection moulding machine, a guard 1, movable between an open position and a closed or safe position in which it covers the tool or working space of the machine, co-operates with a control 5<SP>1</SP> of the machine drive to allow actuation of the machine, and partly overlaps a guard 2 covering the drive mechanism to prevent opening of said guard 2. As shown, the guard 1 is of inverted U-section to cover the sides and top of the space containing mould halves, and is longitudinally slidable, a cam 1<SP>1</SP> thereon actuating an hydraulic valve 5<SP>1</SP> in the drive control system. The guard 1 cannot be closed when the guard 2 is open to allow adjustment of the drive mechanism.
