An apparatus for processing a film has a cutting mechanism for cutting an elongate film, first and second feed mechanisms disposed on respective opposite sides of the cutting mechanism, an inserting mechanism for inserting an end of the film into a spool, and a cam switching mechanism for changing the timing of operation of the cutting mechanism depending on sized films having various different lengths. The sized films having various different lengths can automatically and easily be inserted into spools with a simple arrangement.

A method and apparatus for transferring a workpiece quickly and which can handle a variety of workpieces even of different outside sizes, and can accurately position workpieces. Workpieces on a transfer surface are adjusted in position to maintain an interval between the workpieces at a certain value. Along the transfer surface are disposed two belts on which are provided first and second holders raised above the transfer surface and which contact the workpiece at its front and rear edges. The holders, which are separately formed on the belt, cooperate with each other to hold the workpieces. The apparatus is also provided with a driving force which is able to change the rotational phase between the two belts. By changing the phase between the belts, the interval between the holders in the transfer direction can be varied in accordance with the size of the workpiece to be transferred.

A pair of conveyor lines are provided: one for disassembling a used article sequentially at a plurality of disassembling stations and the other for assembling a new identical article sequentially at a plurality of assembling stations. The disassembling stations are connected to assembling stations in one-to-one relation through a conveyor each. A reusable part of the used article which has been recovered at one of the disassembling stations is transferred by the conveyor to the corresponding assembling station for reuse in the new article, after taking necessary inspection. The conveying directions of these conveyor lines are reverse to each other.

Positions of a tail end of a molded synthetic resin material, which is conveyed precedently, and a leading end of a molded synthetic resin material, which is conveyed following the molded synthetic resin material which is conveyed precedently, are adjusted simultaneously with respect to two reference surfaces, which are close to each other and are spaced a predetermined distance apart from each other. A process is carried out simultaneously on or parts are simultaneously associated with both a portion in the vicinity of the tail end of the molded synthetic resin material, which is conveyed precedently, and a portion in the vicinity of the leading end of the molded synthetic resin material, which is conveyed following the molded synthetic resin material which is conveyed precedently, while the positions of the tail end and the leading end are kept in the adjusted states. Regardless of fluctuations in dimensions of molded synthetic resin materials, the process or parts association is carried out accurately such that the working efficiency may be kept high.

A torsion spring has a coil portion and a leg portion extending from the coil portion. A pin is inserted into the coil portion of the torsion spring in a first position so that the torsion spring is supported by the pin for rotation about the pin. The pin is moved to bring the torsion spring to a second position. The leg portion of the torsion spring is caused to abut against a guide member so that the torsion spring is rotated by a predetermined angle about the pin during the movement from the first position to the second position.

Method of and system for drawing out torsion spring

An .alpha.-shaped torsion springs having a cylindrical coiled portion and first and second leg portions projecting from opposite ends of the coiled portion is conveyed along a conveyor rail. The conveyor rail has a base wall, first and second side wall which project upward on opposite sides of the base wall and extend in parallel to each other, a coil support surface which projects horizontally above the base wall from the second side wall toward the first side wall and terminates at a free edge spaced from the first side wall, and a partition wall which projects horizontally above the base wall from the first side wall toward the second side wall and terminates near the free edge of the coil support surface above the same. The .alpha.-shaped torsion spring is conveyed along the conveyor rail with the coiled portion resting on the coil support surface in a vertical position, the first leg portion projecting above the partition wall and the second leg portion projecting below the partition wall and being spaced from the base wall. The edge of the partition wall opposed to the second side wall prevents the leg portions from interfering with the first side wall during conveyance.

A torsion spring mounting apparatus mounts a torsion spring on a spring support. The torsion spring comprises a leg portion, a coiled portion one end part of which extends to the leg portion, and an engagement portion which extends to the other end part of the coiled portion and which is bent in the radial direction of the coiled portion. The spring support comprises a cylindrical shaft onto which the coiled portion is to be fitted, and a coil engaging protrusion embedded in the circumferential surface of the shaft such that the coil engaging protrusion is normal to the shaft. A spring movement device grasps the torsion spring, and fits the coiled portion onto the shaft by moving the torsion spring along the shaft so that the engagement portion does not overlap the coil engaging protrusion. A push device pushes the leg portion of the torsion spring, which has been fitted onto the shaft, in order to cause the torsion spring to rotate along the circumferential direction of the shaft and make the engagement portion engage with the coil engaging protrusion.

In a magnetic tape cassette, a magnetic tape is accommodated in a casing formed of an upper half and a lower half and is run along a path between a supply reel and a take-up reel. The path has an S-shaped portion defined by a pair of guide members near the take-up reel. The lower casing half has no wall portion standing in the direction of thickness of the cassette within a predetermined distance from a line which is perpendicular to the line joining the centers of the guide members defining the S-shaped portion of the tape running path and intersects the line substantially at the middle between the centers.

Magnetic tape cassette

On a plurality of continuously supplied reel-recording medium assemblies, each comprising a pair of reels and a recording medium wound around the reels, a series of loop formation steps including steps of drawing the recording medium from the reels by a predetermined length, and shaping the drawn part of the tape into a predetermined loop are performed and the reel-recording medium assemblies are successively loaded into a plurality of continuously supplied casings. The loop formation steps are allotted to a plurality of stations, a plurality of the reel-recording medium assemblies are intermittently conveyed to the stations in sequence, and while the respective assemblies are stopped at the stations, the steps allotted to the respective stations are performed on the corresponding assemblies.
