Title: Improvements relating to photographic apparatus
IPC: G03B17/52
Filed: 1968-12-30
Abstract: 1,240,534. Self-processing cameras. INTERNATIONAL POLAROID CORP. Dec. 30, 1968 [March 18, 1968], No.61699/68. Heading G2A. In a camera of the self-processing type containing a stack of film units Fig. 2 (showing two only of such units 35) in a container 36, the uppermost unit being in the exposure position, this unit is engaged by an arm 28 which advances it out of the container into the bite between transport rollers 24, 26. In this position, the film unit disenables the arm 28 from engaging a succeeding film unit until the first unit has been advanced a predetermined distance beyond the rollers. The units are of the type having a pod of processing liquid which is ruptured by the rollers, which then spread the liquid evenly between the photosensitive sheet and the image-receiving sheet. A T-shaped member 14 is mounted so that it can slide longitudinally by means of slots 16 in which engage pins 20 fixed to the camera structure. The cross-piece of the T has a further slot 18, in which engages a pin 22 mounted eccentrically on a gear 25 at the end of roller 24. Gear 25 meshes with a similar gear on roller 26, and the gears are connected by a gear train to a motor, which thus drives the rollers. As roller 24 rotates, the motion of pin 22, engaging in slot 18, causes the member 14 to execute a reciprocating back-andforth movement. Arm 28 is attached to member 14 by a pivot 37, and is biased slightly clockwise, so that the pick-shaped end 30 is urged into contact with the film unit. This has a number of perforation-like openings 34, in one of which the end 30 will engage. The motor is energized when the shutter release trigger is actuated to make an exposure and, after the end 30 of the reciprocating member 28 has engaged in an opening 34, the film unit is drawn to the left, as shown, until its leading edge is gripped between rollers 24, 26. These now feed it through at a uniform speed, and the pod is ruptured to initiate the processing. As the leading edge emerges on the other side of the rollers, it engages against a ledge portion extending from arm 28 across its path of movement, the ledge being shaped as an inclined ramp 32. This causes the arm 28 to pivot anti-clockwise, into the dashed line position, in which end 30 is drawn clear of engagement with a film unit. Thus, although the reciprocating movement may continue, arm 30 is disenabled from engaging and transporting a further film unit until the previous unit has moved completely clear of the ramp. As an alternative to the arrangement of T-shaped member 14 and pivoted arm 28, other film-transporting arrangements are described with reference to Figs. 3 and 4, (not shown) and Figs. 5 and 6 (not shown).

Abstract: Cylindrical articles, e.g. rolls of carpet (26), are delivered to a first wrapping station (29), at which a thermoplastic film (34) is wrapped around each roll (26) by rotation of the roll on driven rollers (28). A heat sealing bar 41 moves downwards into engagement with the film (34) around the roll (26) and seals it along the full length thereof; the wrapping film (34) also being severed by a heated wire (54) close to the roll periphery. Each roll 26 is then ejected from the first wrapping station (29) and delivered to a final wrapping station (63) where companion apparatuses (64 Fig. 12, not shown) and (65) engage projecting end sections of the wrapping film and cause twisting thereof as each roll is again rotated on driven rollers (62). Heat is applied to the twisted film end sections (95) to fuse them, followed by cooling of the film to harden it and form a permanently sealed end closures at the ends of each roll (26). Where a center core is present, the sealed wrapping film snugly embraces the core. Where no core is employed, the twisted sealed film is cleanly severed by a cutter close to the end face (96) or end faces of the carpet roll (26). <IMAGE>
