    摘要: A cylindrical core 1 for receiving windings of a photographic film web comprises a hub 3 having an axial re-entrant channel and an insert 4 fitting into and engaging shoulders 13, 16 of that channel to define with the channel a slot 26 for receiving an end of a film web 2. Cooperating detent elements 19, 25 are provided for resisting relative axial movement between the hub 3 and the insert 4 when the latter is inserted into the channel 11, and the insert 4 incorporates teeth 24 for engaging at least one marginal perforation of a film web to prevent circumferential slippage of the film web. The slot 26 is inclined obliquely from a radial direction, and the teeth 24 are located on the inner or lower wall thereof so that the film perforations are released from the teeth when the film end is tensioned at the end of unwinding.

    摘要: A cassette for holding and rotatably dispensing a roll of web material carried on a rotatable roll is provided with a locking member connecting between the rotatable roll and the cassette body and having a cross-sectionally reduced zone that may be ruptured by rotation of the roll incidental to the initial withdrawal of the web material from the cassette, the reduced zone having at least one inner sub-zone of lesser rupture resistance than the outer sub-zones on each side thereof, e.g., an aperture whereby the reduced zone ruptures upon rotation of the roll through a lesser angle than in the absence of the sub-zone.

    摘要: A light-tight cassette for a roll of light-sensitive photographic material, comprising a shell (11) of generally rectilinear sectional profile with a light-tight dispensing slot (15) defined between two lips, has a stiffening member (33) inserted between at least one lip (21) of the dispensing slot and the adjacent shell wall (19), for increasing the bending resistance of said lip and minimizing accidental light leakage through the slot.

    摘要: A cutting apparatus with two cooperating rotatable cutting knives is driven by a driving shaft rotating at a constant speed and includes a speed controller in the form of an interlocking rotatable pin and slot drive connection, the input and output shafts of that connection offset from each other, and acceleration and deceleration compensating means including a compensating flywheel and an interlocking rotatable pin and slot drive connection having the input and output shafts offset from each other, the input shafts of both slot drive connections being coupled to the driving shaft, the output shafts of both of the connections being held against bodily movement while the input shafts are mounted for parallel bodily displacement, and means for adjusting the position of the input shafts of the slot drives. Preferably, the input shafts have a common axis of rotation.

    摘要: A spreading conveyor comprising an endless air-permeable laterally stretchable spreading band, endless air-permeable supporting band means within the path of the spreading band, and a suction box within the loop of the suction band and having a perforated wall in contact with the inner side of the supporting band means along a portion of its path. This arrangement allows a reduction in the wear and deformation of the spreading band, and can operate at higher speeds than common spreading bands that operate without suction means.
