An apparatus and method are disclosed for plastically deforming and closing an very open, non-cylindrical shell (28) having axially extending lips (20c, 20t) spaced sufficiently far apart to permit a wound spool of strip material to pass laterally between such lips, the apparatus including a pair of closure jaws (670,676) having concave cylindrical surfaces for contacting the exterior surface of such a shell between such lips, the concave surfaces having a curvature corresponding to the desired final cylindrical shape for such a shell; a pivotable arm (608-612) for placing the closure jaws in an open configuration about such a shell and a linkage (614-674) operatively connected to the pivotable arm for closing the closure jaws about such a shell to move such lips into close proximity and form such shell into a cylindrical shape between such lips and thereafter for opening the jaws without contacting the closed shell as the jaws open.

An apparatus and method are disclosed for forming a very open shell (28) having axially extending lips (20c,20t) spaced sufficiently far apart to permit a prewound spool of web material (10) to be inserted radially, laterally into the very open form shell, after which the shell is closed and end caps (24) are installed. Apparatus are disclosed for forming the very open form shell (40), transferring the shell to a mechanism for applying end caps (48), inserting a prewound spool of web material (56) into the very open shell, positioning the spool accurately within the shell (780-856), closing the shell about the spool (58) and staking the end caps in place (60).

An apparatus and method are provided for removing a very open shell (28) from a forming mandrel (76), the mandrel being configured so that when the shell is released from the mandrel, the shell springs to an open form. The apparatus includes a fixture (44) for receiving the shell from the mandrel after the shell has been formed and clamped in place, the fixture comprising a pair of spaced claw elements (308,310) having aligned openings (426) through which the mandrel and the shell can pass with the shell formed and clamped in place on the mandrel, the openings being sized to hold the shell in its open form due to the spring force of the shell, and a support (394) connected between the claw elements for maintaining the alignment of the openings. A universal mount (394,424) for the fixture enables it to be positioned accurately to receive the shell from the mandrel.

A substantially rectangular metal blank is formed about a mandrel (76) to provide a very open shell (28) having a pair of axially extending lips (20c,20t) separated by a distance sufficient to permit a prewound spool (10) or other product to be inserted radially, laterally into the shell prior to closing the shell about the spool or other product.

A winding apparatus has a rotary element, such as a core, that is rotatable about a winding axis. A roller is disposed adjoining the rotary element. The roller and rotary element together define a nip. A guide shoe has a chute wall and a plenum. The chute wall is aligned with the nip. The chute wall has an inner end disposed between the roller and the rotary element and an outer end spaced from the roller. The chute wall has a plurality of bores communicating with the plenum. In use, gas blown through the bores propels a web to the nip in a fluid film. The free end of the web is guided from an outfeed end of the nip in a loop to a second position adjoining the inner end of the guide shoe. During the guiding, the rotary element is rotated against the loop. This continues until the web overlaps and is cinched.

An automatic web winding system for creating a registered perforated web stock roll, from a perforated web, that includes a web leader, a web trailer, and a die assembly that creates the web leader of a first web stock roll and the web trailer of a second web stock roll. A winding assembly automatically wraps and cinches the web trailer to an associated core prior to forming the second web stock roll; and a core loader assembly automatically loads a core onto the winding assembly and transfers the web trailer to winding assembly.

An automated perforated web splicing system includes a web stock roll of a perforated web, supported on a single unwind spindle, and having both a precut web leader edge and a web trailer edge for splicing. Also included in the automated perforated web splicing system is a leader holder device for automatically acquiring and positioning the web leader edge of the web stock roll according to perforations in the perforated web, and a splicing station for automatically positioning the web trailer edge prior to splicing and performing an on-pitch splice according to perforations in the perforated web.
摘要:
In winding methods, a primary nip formed against a web defines continuing and leading web portions. A secondary nip is formed against and moved along the leading portion, from an outfeed side of the primary nip to an infeed side. The continuing portion and a free end of the leading portion are then simultaneously advanced into the primary nip. Winding apparatus has a winding spindle and builder roller that rotate about parallel winding and builder roller axes, respectively. An axle defines a guide axis and carries a cinch roller that rotates about the guide axis. The axle pivots between first and second orientations, in which the guide axis parallels and is transverse to the winding axis, respectively. The axle moves in the first orientation, in an incomplete orbit about the winding spindle from a start to a rotated position, both adjacent the builder roller, and returns in the second orientation.

A photosensitive media cartridge includes an ambient condition sensor mounted in the cartridge for sensing ambient conditions in the cartridge. When the cartridge is positioned at a media transfer position on an image forming device that permits the conveyance of media from the cartridge to the image forming device, image development or printing on the media in the image forming device is controlled based on the sensed ambient conditions in the cartridge.

A film spool comprises a spool core having first and second external core portions movable away from each other to further open a film receiving slot between them to facilitate insertion of a film end into the slot and removal of the film end from the slot, a film engagement protrusion projecting from the first core portion into the slot to engage a film end within the slot and secure the film end to the spool core, and a film stripper protrusion projecting from the second core portion into the slot to disengage a film end from the film engagement protrusion when the core portions are moved away from each other to further open the slot. The film stripper protrusion includes an integral anti-slippage element for holding a film end in engagement with the film engagement protrusion to prevent the film end from slipping off the film engagement protrusion, but is adapted to allow the film end to be disengaged from the film engagement protrusion when the first and second core portions are moved away from each other.
