Abstract: A cotton doffer structure for doffing cotton snagged on a surface having debris. The cotton doffer structure comprises a plurality of single-piece extrusions cooperating to provide a rim. The rim has a longitudinal axis and a periphery with radial protrusions integrally extending outward from the periphery. A shaft is coupled to the rim for rotation therewith about the longitudinal axis in a forward direction and surrounded by the rim. Brushes are provided. Each brush has a base end supporting upstanding bristles, an opposing distal end, a leading side generally facing the forward direction, and an opposing trailing side. Each support member is provided that has a leading end and a trailing end with an upright flange. The brush support member secures a responsive one of the base ends of the plurality of brushes against a respective one of the radial protrusions with the upright flange located adjacent the leading side.

Abstract: A media spindle apparatus for supporting a media roll having media to be delivered to a printing apparatus. The apparatus includes a spindle configured to support the roll. The spindle defines an axial direction about which the roll rotates relative to the printing apparatus to deliver the media to the printing apparatus. A guide member is supported by the spindle and guides the media to the printing apparatus. The guide member is positionable in a first configuration in which a securing mechanism is disengaged and the guide member is translatable substantially in the axial direction relative to the spindle. The guide member is pivotable about the axial direction relative to the spindle to move to a second configuration and thereby engage the securing mechanism to inhibit the guide member from translating in the axial direction relative to the spindle and pivoting from the second configuration to the first configuration.

Abstract: The strap spool is mountable to drive shafts in various strap winding apparatus, such as winches and torsion spring counterbalances. The strap spool has a two piece design where two symmetrical spool halves slidably mate to form a drum around which the strap is wound. Each spool half has a central hub with an axial opening, which allows the spool halves to mount onto a drive shaft. An annular flange extending radially around the hub and a barrel sleeve extends from the hub perpendicular to the flange. When spool halves are mated together on a drive shaft, the barrel sleeves slidably extend into axial openings in the hub of the opposite spool half and form a tubular drum overlying the drive shaft around which the strap is wound.

Abstract: Apparatus for assembling a core for wound sheet material, comprising a tube, a first end member, and a second end member; the apparatus comprising a base, a first chuck for insertion in the first end member, a second chuck for insertion in the second end member, a ram for applying axial pressure such that the first end member is forced into the first end of the tube and the second end member is forced into a second end of the tube, drill devices for drilling fixing apertures, and a monitor device for sensing ambient temperature and enabling the length of the core to be measured at the time of the assembly of the core in the ambient temperature so that the length of the core falls in temperature and length parameters set for subsequent winding of the sheet material on the core.

Abstract: A tape cartridge suitable for high density recording of information signals is provided by enhancing the form accuracy and the assembly precision of a flange fixed to a hub to achieve a high-precision tape reel. The tape reel is placed inside a main casing for winding and storing a recording tape. The tape reel is composed of an upper flange and a hub integrally having a lower flange. The upper flange joined to the upper surface of the hub is fastened and fixed with a screw screwed into the hub from the upper side of the upper flange. The upper flange is fastened and fixed to the hub with a plurality of screws provided in positions away from the central axis of rotation of the tape reel.

Abstract: An adapter assembly for paper roll holders in a printer/plotter comprising ring shaped spacers that increase the diameter of the existing end mounted surfaces of the holder such that a larger size paper roll and be installed.

Abstract: A device for supporting a strip in the wound or spooled condition, includes two half-hubs each having at least one flange (1A, 2A) made by molding with the half-hub, these half-hubs being assembleable together to form a spool. At least one of the half-hubs, called reversible, has a flange (2A) off centered in the direction of the length of the half-hub and is shaped to connect to the other half-hub (1) by either one of its ends (3A, 3B) as a function of the spacing desired between flanges (1 A, 2A).

Abstract: An apparatus for supporting wound flexible media that includes a first flange, a second flange and a fastener. The second flange may be constructed as an integral, unitary structure. A core around which flexible media is wound is typically disposed between the first flange and the second flange. The first fastener has a first end engaging the first flange and a threaded end that is rotatably secured directly to said second flange.

Abstract: A reel configured to store an extended length of composite coiled tubing has a plurality of sections. In one embodiment, the reel has a drum and pair of detachable sidewalls. Each side wall includes a plurality of flanges. In another embodiment, the reel includes a radial splitline that defines substantially identical securably matable sections. Preferably, the reel can store at least 20,000 feet of composite coiled tubing.

Abstract: A paper magazine core for rotatably supporting a roll of photosensitive material in a paper magazine includes an inner core divided into two inner core members that can be screwed together. The surface of each inner core member is provided with rows of screw holes formed at prescribed spacing conforming with the widths of rolls of photosensitive material of various types. Flange members are screw-fastened at the screw holes whose locations are appropriate for the size of the photosensitive material to be used. Each flange member is formed with an insert portion having multiple steps insertable into paper tubes of different sizes. Non-slip portions are formed around the insert portions and surfaces of the steps. Once the flange members have been fastened on the inner core members in a light room, a roll of photosensitive material can be installed on the core in a dark room merely by joining the inner core members.
