Abstract: A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

Abstract: It is known to use the leading edge of a film strip to guide the strip through processing apparatus. However, this leading edge may be damaged as the film is loaded into and unloaded out of a camera. Described herein is a film unloading device in which a curved guillotine blade (240) is used to provide a newly cut leading edge by which a film strip can be guided through processing apparatus. The guillotine blade (240) is reciprocated between a rest and an operative position by a motor which operates in one direction only. The blade (240) is mounted on a rotating drum (250) by means of a crank pin (258), the drum being rotated through 180.degree., in the direction indicated by arrow 252, to move the blade (240) from its rest to its operative position and then through a further 180.degree. to move the blade (240) back to its rest position.

Abstract: A method and apparatus automatically switches from one web media type to another, using a single drive roller to access and drive one of two web media supply cassettes mounted within an imaging system. A gear motor and eccentric shaft position and load the drive roller against either of two driven rollers. The media is nipped between the drive roller and one of the driven rollers and is advanced by the drive roller into the imaging system as needed. To switch media supply cassettes, the media is cut beyond the drive roller. The media is then drawn back into the supply cassette to free the media path for the alternate media to advance from the other of the two media supply cassettes.

Abstract: A paper web having a longitudinally extending zone coat of adhesive is continuously wound around the cylindrical surface of a rotating drum for a selected number of wraps to form a multi-layer cylindrical master stack. Web tension is controlled during winding to cause each succeeding wrap to be placed in relatively greater tension, so that when the completed cylindrical stack is cut transversely and unwrapped from the drum, equalization of the tensile stresses in the web wraps results in a flat master stack of rectangular sheets of equal length. The stack is further processed by cutting along transverse and longitudinal cut lines to form individual pads of adhesive-backed notes. Tension control may be based directly on the increase in drum radius resulting from the buildup of web wraps or by maintenance of print pattern register between continuous equally spaced print patterns in overlying wraps.
Abstract: A photographic film cassette manufacturing apparatus, has a perforator for providing a long film with perforations and a cutter for cutting the long film into individual filmstrips to be contained in the film cassette driven synchronously with transport of the long film. A magnetic recording head for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator and the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, a trailing end of the individual filmstrip in the first direction is moved in a direction which is reverse to the first direction to secure the trailing end to the spool. A cassette shell consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the position of flanges of the spool.
Abstract: A tape cassette is provided which has indicia indicating the characteristics of the tape contained therein. In one embodiment an information discriminating mark, capable of being optically sensed is provided on the magnetic tape. Fluctuations in the transmittance of the tape are detected by a photodetector device and a difference in the detected output is utilized for identifying the type of the tape cassette. In another embodiment, the bottom surface of the tape cassette is provided with physical indicia indicating the characteristics of the tape contained therein.
Abstract: A winding apparatus winds up a continuously fed web of material onto a number of winding cores. Shortly before removing a finished roll from a main winding location, a drive mechanism is coupled onto a winding core, located in a waiting position. The drive mechanism drives the winding core before the core is set down on a web of material running over a winding drum. The winding core remains driven until the winding core with already wound-up web of material has been transferred at the main winding location onto bearing arms. Due to the continuing driving of the winding core during a change of rolls, qualitatively high-grade rolls can be wound with a wide variety of webs of material.
Abstract: A continuous log roll winder cuts and transfers on the fly without stopping the winding process. The web passes around a rotating drum with the adhesive side out and travels to a wind-up spindle. A knife cuts the web against the surface of the drum. By heating the knife to temperatures above 300.degree. F., the web and adhesive does not stick to the knife; the adhesive does not accumulate on the knife; and the adhesive does not transfer through the cut in the web backing and deposit on the rotating drum.

Abstract: A moving web (1) is severed, after the intended length has been wound up, by fracture mechanical crack propagation starting from perforation cuts introduced by means of a laser system (9-11) into a web material embrittled by cooling (8) at the severance location.
Abstract: A web winding apparatus including a main winding drum and a web separator roll which are operatively interconnected to rotate in synchronism. The drum has a channel in the surface thereof. The roll has a cutter blade projecting from the surface thereof. At selected times during synchronous rotation of the drum and the roll the cutter blade is forced into the channel to move the web into the channel and tear the web in the channel. A hook blade having a large number of hooks is mounted at the fore side of the channel. Edges of the hooks are arranged side by side in a rearward looking pattern in the direction of rotation of the drum. Therefore, when the cutter blade plunges into the channel and the web is torn in the channel, the tail edge of the separated web is caught by the hook and held against the surface of the drum.
