1,203,179. Cine-film loading apparatus. GAF CORP. Oct.25, 1968 [Oct.30, 1967], No.50695/68. Headings G2A and G2E. Cine-film is inserted into a cassette having a planar film supporting plate and two centrally located raised portions by winding a predetermined length of film w about a rotatable spindle member 16, staking the trailing edge of the film to a takeup core 40, superimposing the cartridge body film supporting plate on the spindle member while concurrently lowering the latter whereby the spindle member is replaced by one of the raised portions for supporting the scroll of film, conveying the cartridge body and film to an adjustable guide plate assembly 70, and mounting the take-up core and staked film end on the other of the raised portions. The plate assembly 70 is moved downwardly and the cartridge and film assembly finally encompassed with a cartridge cover, whilst the loaded film cartridge is being removed a further length of film may be wound around the spindle. The apparatus 10 includes a flat table-top or work reference surface 12 and may be part of and mounted upon a common work plane with a film supply device, film footage counter and film punch and cutter (not shown). The spindle is driven via a belt drive by an electric motor 20 mounted beneath surface 12, the belt passing over a pulley (58) Fig. 3 (not shown) which is keyed into an elongated slot (64) of the spindle to permit the downward movement of the spindle. The take-up core 40 is mounted in a staking assembly 30 which includes a guide rail 28 and an arcuate fixture plate 32, a clutch 42 and manually operable lever 44 imposing a damping force upon the take-up core. The film may be glued, cemented, taped or crimped to the take-up core. A lever 46, 48 is provided for lowering the spindle, and a constant surface pressure is maintained on the winding film by a roller 84 mounted on a pivotable arm 80.
