Abstract

1,094,175. Photo-electric machinery guards. SCHNEIDER Lt BECK GRAPHISCHE MASCHINENUND APPARATEBAU G.m.b.H. Feb. 16, 1966, No. 6825/66. Heading F2J. The operator of a paper-cutting machine is protected from the knife by a light curtain provided by a single light source 5, located at one side of the machine work-table, which radiates light through converging lenses 6 on to a corresponding number of reflectors 7, preferably arranged with their centres in a plane normal to the plane of movement of the knife, which direct the light beams across the table, parallel to its surface, on to a corresponding number of photo-electric cells or light sensitive resistors located at the other side of the table, the drive to the knife and to a presser arm being cut out if any beam is interrupted.
