Abstract

1,261,145. Trimming moulded gramophone records. DEUTSCHE GRAMMOPHON G.m.b.H. 26 June, 1970 [19 Sept., 1969], No. 31106/70. Heading B5A. Moulding flash 18 is removed from a gramophone record held by a suction plate 16, by a cutting stylus 10 rotated concentrically around the record on an arm 11. The arm is secured to a spindle 12 in a housing and the spindle is attached to a gear-wheel 14 engaging a toothed rack 17, so that when the housing is moved rectilinearly relative to the rack the arm is rotated and the removed flash falls into a container 19. In a modification the housing is stationary and the stylus arm is attached to the armature shaft of an electric motor in the housing.
