Abstract: A coreless roll of product that is self-supporting in a rotary dispenser. The roll includes a rolled web of product that is wound throughout its diameter about a winding axis into a cylinder having first and second flat ends. At least one flat end defines a mounting hole at substantially the center of the winding axis of the coreless roll. The mounting hole has a depth and has sides generally perpendicular to the end of the roll. The sides are separated by a distance that is less than the depth of the hole such that the mounting hole is adapted to receive a plunger from a rotary dispenser. Methods of making the coreless roll are also described.

Thus, the position of and distance between the reel tables are determined by the rotation angle of the rotating arms.

Abstract: A movie film cassette comprises a light-tight casing containing an unexposed film reel and adapted to contain, after shooting, an exposed film reel. The reels and the film are positioned so that, in an operating position within a reception device associated with a movie camera, no moving element, located in the casing and contacting the film, is in contact with a fixed element of the casing.

Abstract: A combination of a tape cassette and a tape drive motor wherein a shaft is connected to a tape reel. A tape reel support is mounted to the housing of the cassette and a tape reel shaft extends through the support. Bearings are carried by the support for rotatably supporting the tape reel shaft and thereby the tape reel on the cassette housing. The motor has a rotor rotatable about an axis with the rotor being loosely mounted in the motor when a cassette is not in the tape drive. In one embodiment of the invention, the rotor carries a magnet which in combination with magnetically attractive material carried by the shaft, operates to connect the rotor to the shaft to effect a driving relationship between the rotor and shaft when the cassette is in the tape drive. The bearings on the cassette for the tape reel shaft served as the sole bearings for the rotor for rotational support when the rotor rotates and drives the shaft and thereby the tape reel.

Abstract: An apparatus and processes for making and using the same, for holding tape media for use in compact computer tape drives. Tape media cartridges for use in compact computer tape drives have a single reel for holding the tape media, and include a leader block coupled to the tape media. When inserted into the tape drive, a leader block handling mechanism within the tape drive grips the leader block and threads the tape media on a take up reel in the tape drive. The apparatus permits the leader block handling mechanism to more easily grip the leader block, and promotes more compact designs for tape media cartridges and tape drives.

Abstract: A photo film cassette includes a spool for winding the photo film thereabout, and a cassette shell for containing the spool in a rotatable manner. The spool has first and second ends disposed to appear outside the cassette shell. To manufacture the photo film cassette, a cassette shell with the spool is retained while confronting a drive shaft with the first end and confronting a support shaft with the second end. The support shaft is slid in an axial direction, to support the second end. The spool is displaced via the support shaft to a braked state where rotation of the spool is blocked. The spool is displaceable between the braked state and a released state. The drive shaft is rotated and slid while the spool is in the braked state, to engage the drive shaft with the first end in a key-engaged manner. After the drive shaft is engaged with the first end, the spool is displaced from the braked state to the released state.
