The second link is rotatably connected to the frame and includes a first end supported relative to the frame. The middle link includes a first end rotatably connected to a second end of the first link and a second end rotatably connected to a second end of the second link.

Abstract: Provided are a small tape feeder for a component mounter, which can transfer one or more strips of tape and can insert the tapes into a tape guide easily and precisely, and a method of automatically setting a tape initial position for such a tape feeder. The tape feeder includes a frame; at least one index pin, which is mounted on one side of the frame and transfers a tape by being inserted into one of tape holes, in which electronic components are received, and moves forwardly; a pin moving unit, which includes a pin horizontally moving member for horizontally moving the index pin, and a pin vertically moving member for vertically moving the index pin so that the index pin can be inserted into or removed from the tape hole; and a top cover discharging unit, which is installed on the other side of the frame and discharges a top cover detached from the tape.

Abstract: A perforated filmstrip transportation and registration system (100) and method provide a substrate in the form of a rotating drum (104) with vacuum holes (106) to allow an internally produced vacuum to act upon an engaged filmstrip (102). The rotating drum (104) has a number of registration-tension pin pair assemblies (216) that register and subsequently advance a filmstrip (102) at the 3 o'clock position in a registration mode (FIGS. 2 and 3), and are ready to be inserted in filmstrip perforations (208) when they approach the 3 o'clock position in a load mode (FIG. 4). The registration-tension pin pair assemblies (216) each contain a registration pin (220) and a tension pin (230) which are sized small enough to fit into filmstrip perforations (208) without interference, and which move away and towards each other in the nature of scissors blades in the preferred embodiment.

Abstract: A method to fabricate plastic cards is disclosed. A substrate tape is perforated with evenly spaced holes, and when placed in a working station, positioning pins engage into the holes. The spacing between two sets of pins is then slightly increased thereby tensioning the tape without stretching it thereby providing for highly accurate alignment.

Abstract: A film transport mechanism for transporting film having perforations including a motor that drives sprockets for transporting the film in increments defined by a pull down stroke. In addition, the mechanism includes a pin element having at least one pin, the pin element being rotatable to a first position wherein the pin is inserted into an associated perforation to stabilize the film without contacting a perforation edge to generate a first sound level when the pull down stroke substantially equals a perforation pitch. Further, when the pitch is not equal to the pull down stroke, the pin contacts a perforation edge to generate a second sound level. The mechanism also includes a microphone positioned adjacent the pin element and the film for detecting a range of sound levels.

Abstract: A film registration gate assembly has a gate with focal positioning location for focal positioning of an image frame of a strip film with edge perforations. Undersized first and second pins enter a pair of transversely aligned perforations of the film to register the image frame with the positioning location. An undersized third pin enters a third perforation spaced along the film from the second pin and then pulls the film obliquely to a reference line extending between the first and second pins to nest against the first and second pins the perforations thereat and register the image frame precisely at the aperture. A plate with a window registering with the image frame and aperture clamps the film against the gate. The window, positioning location and image frame are of corresponding size and shape. The pins register the image frame precisely with the positioning location, and the plate maintains the image frame in precise focal position thereat.

Abstract: A film registration and ironing gate assembly has a gate with a positioning location or aperture for focal positioning of an image frame of a strip film with edge perforations. Undersized first and second pins enter a pair of transversely aligned perforations of the film to register the image frame with the aperture. An undersized third pin enters a third perforation spaced along the film from the second pin and then pulls the film obliquely to a reference line extending between the first and second pins to nest against the first and second pins the perforations thereat and register the image frame precisely at the positioning location or aperture. A pair of flexible bands extending along the film edges adjacent the positioning location move progressively into incrementally increasing contact with the film to iron it and clamp its perforations against the gate. The pins register the image frame precisely with the positioning location, and the bands maintain the image frame in precise focal position thereat.

Abstract: A two piece feed member providing a less costly replacement and the ability to adjust the feed member's length. The two piece configuration only requires that the wearing portion be replaced, and not the entire feed member. This allows for a significant cost savings. Different feed mechanisms require different length feed members, and therefore, an adjustable length feed member allows for the use of one universal feed member.

Abstract: Three registration pins align a mask or other superimposed image with a film strip in both the lateral and longitudinal axes. A compactly constructed shutter and support apparatus permits placement of the shutter in close proximity with a film strip to minimize weight and moment of inertia of the shutter to permit rapid repetitive starting and stopping of the shutter in response to control signals to a drive mechanism. Film boxes are keyed to and secured by thumb screws to the shutter housing to permit detachment and accurate reattachment; light restrictive devices negate transmission of light into each film box upon removal. A longitudinally displaceable film reel drive permits rapid disengagement and reengagement of the film boxes without careful alignment and a belt drive prevents, through slippage, film tearing forces.

Abstract: Stamping and forming machine has first and second tooling assemblies which are movable relatively towards and away from each other. Pilot pins are mounted on, and moved with, the first tooling assembly. The pilot pins enter pilot holes in the strip material and are movable on the first tooling assembly between extended positions and retracted positions. When the tooling assemblies are in their open, or separated, positions, the pilot pins are in their retracted positions and clearance is provided to permit feeding of the strip between the two tooling assemblies. As the tooling assemblies move to their closed positions, the pilot pins move to their extended positions and perform their piloting function. The pilot pins are actuated by an actuator which is separate from the actuator which moves the tooling assemblies.

Abstract: A film transport device for cinematographic cameras and projectors has a rotary shutter, an intermittently operating film feed device, an adjusting device with at least one adjusting pin engaging in one perforation of the film and separate drive motors for the rotary shutter, adjusting device and film feed device and is further characterized by having the drives for both the adjusting device and for the film feed controlled synchronously with the rotary shutter by a common control unit.

Abstract: There is disclosed a film pull-down mechanism comprising a four-pivot linkage with two additional links attached thereto. The two additional links are mounted between a plane containing the film and a plane intersecting the drive means of the mechanism.
