Abstract: There is provided a method for plastic film surface treatment for improving printability and adhesion properties which comprises feeding a plastic film and a wiping web in the opposite direction to each other in a ratio of the film running speed to the wiping web running speed being 1/1 to 100/1 and bringing them into contact with each other between knip rolls under a proper pressure, whereby a weak layer containing oligomers and additives is wiped off from the plastic film surface. The treatment improves the printability and adhesion of film inexpensively in a stable manner without being affected by the varied properties of film to be treated and also without deteriorating the physical properties of the film.

Abstract: An elongated film strip is cleaned by two pairs of rotary brushes with soft bristles contacting opposite sides of the film strip traveling between the two pairs of brushes. Each pair of brushes is placed at an angle to the direction of film travel for brushing dirt particles away from the center of the film. The top pair of brushes and the bottom pair of brushes are arranged so that one brush in each pair brushes the particles from the central region of the film toward one edge of the film, while the other brush on the same side of the film brushes particles away from the central region of the film toward the other edge of the film. The brushes avoid contact with perforations on the edge of the film which would result in particles lodged in the perforations being brushed toward the central region of the film. A separately electrically conductive vacuum tube contacts each brush after the brush contacts the film.

Thus, the take-up rolls are driven by the friction-driven roll and essentially clean portions of the tapes contact the film.

Abstract: An ultrasonic liquid film cleaning device having means for moving a film strip at high speeds between a pair of oppositely moving cleaning strips. The cleaning strips and the film are positioned for movement between a pair of beds which act as guides and compression surfaces for the sandwiched assembly of cleaning strips and film.

Abstract: Strips of photographic material which are treated during travel through liquid baths in a developing machine are relieved of surplus liquid during travel from a preceding bath into the next-following bath. The intercepting apparatus has a wiper with two elastic intercepting members engaging the respective sides of the moving strip and a pivotable support for the wiper. The support can move transversely of the direction of movement of the strip in order to insure that the intercepting members remain in continuous engagement with a fluttering strip as well as with a strip moving along a path which deviates from the path of movement of the preceding strip. The wiper is detachable from its support for convenience of cleaning. Each intercepting member has a strip-engaging lip which can resemble a wedge or a flat lamina and is connected to the adjacent part of the respective intercepting member by a flexible hinge.

Abstract: The arrangement is used for continuously cleaning surface-sensitive paper or film in web form. The arrangement may be installed at any point along the path of web travel. The cleaning effect is provided by a ribbon of fibrous nonwoven material which is guided over a suction roller together with the web to be cleaned. The ribbon of fibrous nonwoven material moves in the opposite direction to the web. A highly satisfactory cleaning effect is obtained by the high relative speed between the surface to be cleaned and the web of nonwoven material. The particles of dust and dirt removed from the web are drawn into the suction roller under the effect of the vacuum.

Abstract: A device for cleaning foreign material from at least one surface of a sheet including at least one low durometer sheet cleaning roller having a tacky peripheral surface. The surface of the sheet to be cleaned is biased against and moved generally tangentially across the tacky peripheral surface of the cleaning roller with rolling contact therebetween so that foreign material on the surface of the sheet will be adhered to the tacky surface of the cleaning roller. The tacky surface of the cleaning roller is in turn cleaned by bringing into rolling contact therewith a surface on a roller cleaning member (which surface may be provided by the adhesive on a length of tape) having a higher surface tack than the cleaning roller. In one embodiment of the device the roller cleaning member is periodically passed over the cleaning roller by the operator of the device, whereas other embodiments automatically pass the roller cleaning member over the cleaning roller during each cycle of the device to clean a sheet.

Abstract: The photoreceptor cleaning composition is provided which includes a lower alcohol, ultrapure water and a surfactant, 3,5-dimethyl-1-hexyn-3-ol. This cleaning solution is 100% volatile, water-clear, and is found to contain no solids or colloidal matter, in addition to being contaminant- and particulate-free, it is found to leave no detectable residue even if not fully wiped off in a cleaning operation. The most significant property of this photoreceptor cleaning solution is its ability to retard crystallization of the photoreceptor, which has been found to be a major problem with many known photoreceptor cleaning solutions.

Abstract: An automatic self-contained basic unit-processor for an offset photolithographic plate which may be used, at different times, for any processing step requiring contacting of the plate by liquid. For example, an exposed plate is developed by contacting the exposed surface of the plate with the conventional developing fluid, and subjecting the surface to a linear, reciprocating rubbing action by a sponge. This rubbing action produces results surprisingly similar to those produced by a manual rotary action. A fully assembled basic-unit processor of this invention requires only that it be connected to a source of power, and to a reservoir for recirculatable processing fluid. A single electric motor is adapted (a) to drive each roll of two pairs of coupled drive rolls, (b) to reciprocate a sponge in frictional contact with a generally horizontal offset plate, and (c) to supply a controllable flow rate of fluid for processing the plate.

Abstract: A motor drives a film strip take-up reel to draw moving picture film from a freely rotating film supply reel through a film cleaner including a pair of oppositely rotating brushes also driven from said motor. The brushes are disposed on aligned and parallel shafts disposed at a level below that of the supply reel and above that of the take-up reel; with the film following a path generally downwardly from the supply reel about the lower portion of the cleaner brush closest to the film supply reel, up between the cleaner brushes and over the upper portion of the film cleaner brush closest to the film take-up reel, and thereafter generally downwardly onto the film take-up reel. The film path so taken by the film provides for an appropriate tension on the film which in turn insures efficient and proper film cleaning.

Abstract: A cleaning fabric having a contact surface against which the surface of a photographic film can be rubbed to remove foreign particles from the film. The fabric is a laminate comprising a non-woven wiping layer of soft fine intersecting bonded fibers defining the contact surface. The fibers in the wiping layer are randomly spaced and disposed to provide openings in the wiping layer for receiving foreign particles, and the wiping layer is compacted in a direction normal to the contact surface so that few ends or loops of the fibers project past the wiping surface, thereby restricting shearing or tearing loose of the fibers by the edges of a passing photographic film. An open non-woven lofty backing layer is adhered to the surface of the wiping layer opposite the contact surface.
