7 and 7a in parallel relation the shafts being slidably received in the circular grooves 10 formed in the undersurface of the top plate 20 the three openings 16c in the top plate 20 communicate with the groove 10 formed in the underside of the plate so that as the suction bore 16a in the shaft for the pinion 7 passes the openings 16c in the plate 20 a sufficient suction will be delivered at the entrance for the bore 16a to cause the hair in the strand disposed adjacent to the paddle 2a to be drawn into a parallel arrangement with the axis of the suction bore and just prior to the paddle 2b being swung back into hair gripping relation with its associate paddle 2a returning now to the figure eight movement taken by all three discs 9b as they are moved by their pairs of shafts for the pinions 7 and 7a fig3 shows a bottom view of these three discs and their relation to each other the left hand disc in this figure is just passing one of the three high points 25 in the cam groove 4 and the paddles 2a and 2b are shown in open position ready to grasp a lock or strand of hair that has just been separated by the two left hand hair parters 1 the left hand disc 9b is moving in a clockwise direction and the disc stud 9a is riding in the circular cam groove 4 in the middle plate 19 the other disc stud 9c is riding in the cylindrical opening 3 in the middle plate 19 the middle disc 9b shown.
