922,743. Doffing-coils of filamentary material. ETABLISSEMENTS G. DECOMBE. Jan. 21, 1960 [March 23, 1959], No. 2265/60. Class 120 (2). A spool arrangement on which a coil of wire, cable, thread or the like may be wound comprises a flange 2 revolvably mounted in a stationary wall 4, an axially movable flange 11 and an axially movable core drum 5. When a coil 6 is fully wound the core 5 is retracted by a shaft 8 sliding in a portion 12 of a unitary member 11, 10, 12, 13. During this retraction the wall 7 of the core contacts the vertical wall of the member 11, 10, 12, 13 and axially displaces it against the spring 14 to the position shown in Fig. 4. The coil 6 then drops away between the stationary walls 15, 16 preferably to be guided by a hopper arrangement into a box for immediate packing: a pusher member may be provided to assist in removing the coil. The spool arrangement is driven at the pulley 13, the core 5 and flange 2 being driven by friction from the member 11, 10, 12, 13. In a further form the coil receiving drum is mounted on a spindle which may be retracted therefrom to allow the coil to fall away with its receiving drum still inside. Means may also be provided for adjusting the spacing of the flanges 2 and 11 and of the stationary walls 15 and 16. |
