Abstract: A package (30) for an individual charging wire (10) includes a backing (32) having a back portion (42) and a front portion (44). A first perforation (46) is defined in the backing (32) between the back portion (42) and the front portion (44). A closing strip (36) is disposed on the back portion (42). A padding strip (34) is disposed on the back portion (42) between the closing strip (36) and the first perforation (46). A second perforation (48) is defined in the back portion (42) between the closing strip (36) and the padding strip (34).

Abstract: In an apparatus for cleaning particulates from a moving web, a dust seal blade assembly which is easily mounted to a cleaning blade to reduce internal dusting in a cleaner apparatus and for trapping of lint, paper dust, or fibrous material and which might also reduce the effects of oil contamination. The arrangement provides a low-cost, operator-replaceable cartridge having one or more wiper blades with at least one of them having the dust seal blade assembly and enclosed within a particle sump assembly that is easily removed from association with the web being cleaned.

Abstract: A cleaning station for removing particulate material from a moving web in an electrostatic printer/copier includes a customer-replaceable web-cleaning cartridge and a support bracket/backup shoe assembly. The latter serves to support the cleaning cartridge for movement between an operative position in which web-cleaning components of the cartridge exert a substantially uniform pressure on the web, and a service position in which the cartridge is sufficiently spaced from the web to facilitate replacement and/or service. Preferably, a bracket that supports the cleaning cartridge is pivotally connected to a backup shoe that is fixed with respect to the web path and exerts a uniform pressure on the rear surface of the web, opposite that contacted by the cleaning cartridge. A quick disconnect feature enables the cartridge-supporting bracket to be de-coupled from the back-up shoe and removed from the instrument.

Abstract: A cleaner for removing particulate material from the surface of a moving web having a customer-replaceable cleaning cartridge including a pair of spaced, parallel cleaning blades supported by a sump housing having an easily removable lid assembly with a narrow opening through which the blades project at an angle, the lid member has slot features for locking it to the sump housing tabs and preferably, the lid member is sealed against the sump housing by compression of a foam gasket; a backup shoe assembly positioned to contact the web surface opposite the cleaning blades and provide resistance to the cleaning blades; and a bracket assembly for releasably supporting the cleaning cartridge in an operative position in which the cleaning blades contact the web surface to be cleaned and cooperate with the shoe assembly to wipe particulate material from the web.

Abstract: Apparatus for cleaning particulate material from the surface of a moving web comprises: (i) a customer-replaceable cleaning cartridge including a pair of spaced, parallel cleaning blades supported by a sump housing having a removable lid assembly with a narrow opening through which the blades project at an angle; (ii) a backup shoe assembly positioned to contact the web surface opposite the cleaning blades and provide resistance to the cleaning blades; and (iii) a bracket assembly for releasably supporting the cleaning cartridge in an operative position in which the cleaning blades contact the web surface to be cleaned and cooperate with the shoe assembly to wipe particulate material from the web. Preferably, the lid assembly comprises a lid member that supports a flexible seal blade that contacts the web surface upstream of the cleaning blades and deflects particulate material wiped from the web by the cleaning blades into the sump housing.

Abstract: A support and tensioning device for an elongated corona generating electrode includes a corona charger shield member that includes a first set of wall members for serving as a shield for a corona generating electrode. The shield member includes a second set of wall members shaped to define a recess formed at one end of the shield member for receiving therein a plunger member and a spring. The recess includes an inner positioned land for engaging a head end of the spring. The second set of wall members define the recess and include walls located to define a key slot opening which extends in a longitudinal direction of the shield member. A spring resides in the recess and engages the land to restrict movement of the spring within the recess. A hollow plunger member has a generally cylindrical sidewall for supporting the plunger for rotational movement in the recess and a land on or near a head end portion of the plunger member engages a tail end of the spring.

Abstract: A corona charger and integral latch member device includes a corona charger having a longitudinally ending wall and a corona generating electrode extending generally parallel with the longitudinally extending wall and spaced a predetermined distance therefrom. A latch member has a portion integrally molded with the wall proximate one end of the charger to define part of a bearing surface for engaging a first axially directed member of a roller. The bearing surface is spaced from the wall so as to determine a location of the corona-generating electrode relative to the axially directed member.

Abstract: A mechanism for mounting a transfer assembly in a reproduction apparatus, the reproduction apparatus having a transfer assembly including an electrically biased transfer roller for effecting transfer of pigmented marking particle images from a dielectric member to receiver members. The transfer assembly mounting mechanism includes a tie bar weldment for supporting the transfer assembly within the reproduction apparatus. A bracket, coupled to the transfer assembly, connects the tie bar weldment to the transfer assembly such that the transfer roller of the transfer assembly is castered and gimbaled.
