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 web cleaning device for cleaning contaminants from a moving surface in a printer apparatus. The cleaning device includes a nesting structure having a longitudinally extending internal surface for supporting a coil of a web fabric extending in a longitudinal direction and an external surface located opposite to the internal surface. A lip member forms a part of the nesting structure and is located adjacent a pay out end of the coil. The pay out end of the coil is wrapped about the lip member and further wrapped about the external surface of the nesting structure. The web fabric is also wound about a take-up spindle that is spaced from the coil. A portion of the web fabric from the pay out end of the coil to the external surface of the nesting structure provides a hairpin type curvature to the path of the web fabric to reduce tendency of the web fabric to bind during pay out of the web fabric from the pay out end of the coil.
