After being preliminarily unwound, the film is positively engaged and fed by advancing rollers.

Abstract: A horizontal type of open-reel magnetic tape drive unit automatically clamps a tape reel in a drive section after the reel is inserted, then separates the free end of the tape from the reel, and guides the free end of the tape along a tape transport path to be wound onto a take-up hub, with these separation and guidance operations being performed by a small number of high pressure air jets. Pressure sealing of the unit is unnecessary, and the overall configuration is simple and easily manufactured.

Abstract: An automatic film threading apparatus (10) that allows roll-film (58) to be automatically threaded through a series of film developing and processing chambers (12a) located on a roll-film processor (50). The apparatus is further comprised of a powered film spool (52a) and a pinch roller (16a) disposed above the spool to form a rolling intersection. A spool and roller combination is located between the upper ports (12b) of each chamber pair. Also located above and below each chamber pair is an upper and a lower film guide (18) (56). Automatic threading is accomplished by extracting a small section of film (58) from its reel (14b) and attaching the film to one end of a threading leader assembly (15). The other end of the threading leader is then manually threaded through a first chamber pair where a threading tip (15c) engages the rolling intersection of the roller (16a) and spool (52a). From this point on, the film (58) is automatically threaded through each successive chamber (12a).

Abstract: Apparatus and methods are disclosed for properly positioning the machine reel in a magnetic tape drive containing an automatic tape threading mechanism, wherein the file reel consists of a tape cartridge with tape attached to a leader block. The automatic threading mechanism connects to the leader block and pulls the tape through the tape path to insert the leader block into the hub of the machine reel.

Abstract: In a method for guiding the leader of the web in the drying section of a paper machine, a narrow leader is cut out of the full-width web by water jets, or the equivalent, such as, for example, against a roller of the press section. The leader is guided by a plurality of air jets into a gap between threading ropes and is carried between the threading ropes over drying cylinders. The leader is detached from a rock roller of the press section by a first plurality of air jets and is guided by a second plurality of air jets into connection with a drying wire in the drying section of the paper machine. A third plurality of air jets are directed through the drying wire to the leader supported on the drying wire and detach the leader from the drying wire. Substantially immediately upon detachment of the leader from the drying wire, transverse air jets are directed at the leader and shift the leader into the gap between the threading ropes and move the leader between the threading ropes over the drying cylinders.

The transport is mounted on a support frame, which is in turn mounted for sliding movement in a housing. A drive belt roller is mechanically coupled to movement of the support frame, and withdrawal of the support frame from the housing results in movement of the drive belt roller and disengagement of the belt from the supply tape pack, to facilitate tape loading and unloading. Drive belt pick-off posts affixed to the housing retain a portion of the drive belt in the housing, to maintain belt tension during tape loading and unloading, and to ensure disengagement from the supply tape pack.

Abstract: An automatic threading apparatus for a magnetic tape transport is disclosed using a constant force spring located outside of the plane of the tape path. A leader block attached to the free end of the tape from a cartridge is connected to a pick-up pin of the threading apparatus.

A motor raises a violator probe after the cassette is in place to guide the backing paper between a pair of powered rollers which draw the backing strip from the cartridge thereby carrying the film into the film guide. The backing strip is discharged through a series of ducts to be discharged outside the machine.

Abstract: A perforated form band is introduced into a form printer through an input passage or shaft. The passage is formed by spaced walls and is pivotally mounted on the printer for movement between an input position and a working position.

In one embodiment, the leading end of the form band contacts transversely extending stop surfaces, while in another the leading end of the form band is aligned with an indicating mark and the perforations on the form band engage with projections in the input passage. With the form band aligned, the input passage is moved into the working position engaging the perforations in the form band on pins projecting outwardly from sprocket wheels which drive the form band through the printer. In the working position of the input passage, the form band no longer contacts the stop surfaces or engages the projections used in the aligning operation.

Abstract: Supply and take-up reels are mounted above a horizontal base for selective powered rotation about respective vertical axes. Vertical guide surfaces and a cover panel define an air tight continuous flowpath extending between the peripheries of the reels past a read/write head. A blower mounted in a hood structure beneath the base sucks air through the flowpath and through a perforated center spool of the take-up reel. A river of air thus pulls and guides the free end portion of the magnetic tape from the supply reel to the take-up reel as the supply reel is rotated by a drive motor to unwind the tape therefrom. The supply hub is adapted to automatically center the supply reel thereon. The supply hub further includes a plurality of annularly spaced reel engaging pawls mounted in, and normally retracted into the hub, and an over-center actuating means for selectively extending the pawls through differential rotation of a pair of separate rotors included in the hub.

Abstract: A container for exposed photographic roll film is so positioned in a film removing apparatus that the observation and exposure openings of its bridge register with a pivotable pusher which thereupon moves forwardly to expel the leader of the backing strip into the nip of a first pair of advancing rolls. The backing strip extracts the film from the takeup section of the container, and a deflector causes the leader of the film to enter a channel wherein the film advances toward a second pair of advancing rolls. The deflector and/or the first pair of advancing rolls defines for the backing strip a path which makes an angle of 30.degree.-60.degree. with the direction of travel of backing strip from the takeup section of the container toward the exposure opening. This insures that the film is not scratched during withdrawal, even if it is tightly wound onto the takeup reel and even if the dimensions of the container deviate from optimum dimensions.
