Abstract

1,079,482. Film spool. PAILLARD S.A. Jan. 27, 1966 [Feb. 18, 1965], No. 3650/66. Heading B8M. [Also in Division G2] Automatic securing of a film end to a take-up spool is facilitated by providing the inner surfaces of flanges 1, 2 with resilient radial rods 10, 10<SP>1</SP>, the rods on one flange being off-set with respect to those on the other. The ends of rods 10 enter slots (7) and (9) in the flange and hub (3) respectively, as in Fig. 3 (not shown). Rods 10, 10<SP>1</SP> frictionally engage the film end and carry it towards hub 3 since the peripheral speed of the take-up reel is higher than the speed at which the film is fed. Rods 10 may be replaced by tongues pressed out in the case of metal flanges.
