Abstract: An apparatus and method for joining webs has clamp assemblage which includes a pair of clamp members for securing and moving a trailing end of an expiring web into a spaced relations with the leading end of a fresh web. An actuator moves the clamp members securing the expiring web along guide rails to a predetermined position for setting the gap width between the ends of web.

Abstract: An apparatus and method for setting a gap between webs has a clamp assemblage which includes a pair of clamp members for securing and moving a trailing end of an expiring web into a spaced relations with the leading end of a fresh web. An actuator moves the clamp members securing the expiring web along guide rails to a predetermined position for setting the gap width between the ends of web.

Abstract: An apparatus and method for continuously self aligning a first surface with a second roller has an adjustable support member for the first surface which produces movements of the first roller that corresponds to movements of the second roller. The adjustable support member supporting the first roller uses a plurality of bearings, preferably thrust bearings, arranged on the frame supporting the first roller which alignable controls the movements of the first roller in contact with the second roller.

Abstract: Apparatus is disclosed for treating a movable surface with material which has been removed from an erodable bar of such material. A movable applicator is adapted to brush against the bar and to transfer eroded material to the movable surface. The bar is cylindrical and mounted for rotation about its longitudinal axis to present a continuously changing portion of its periphery to the applicator. By causing the bar to rotate, the peripheries of the applicator and the bar move at relative speeds less than that which would cause objectionable dusting to occur. The bar is mounted for movement generally toward the rotatable applicator to maintain contact therebetween as the bar wears. The pressure between the bar and the applicator is maintained partially by gravitational force and partially by magnetic force.

Abstract: A cleaning apparatus includes a magnetic cleaning brush for removing residual toner from a photoconductor. A hollow rotating detoning roller electrostatically removes toner from the cleaning brush. The detoning roller has apertures in the surface thereof allowing toner to be mechanically swept by a skiving blade into the hollow portion of the detoning roller. A stationary auger transports the toner to one end of the roller where it may be vacuumed up.
