  • Patent number: 4294533
    Abstract: An apparatus for removing dirt from an exposed film as it is advanced to an image developing unit includes a scrub roll with a spongy surface and a second roll in engagement therewith for transporting the film. A conduit with perforations directed at the scrub roll is positioned thereabove and is connected to a source of flushing liquid. The transport and scrub rolls are driven co-currently at different surface speeds to generate a scrubbing, shearing action along with simultaneous wetting of the film surface to remove most of any dust or dirt previously carried by or embedded in the surface of the film.

  • Patent number: 4255038
    Abstract: A photographic processing machine has a plurality of rollers for transporting the photographic materials through a processing bath. According to this invention, alternate ones of adjacent rollers are provided with a flexible casing subject to internal hydraulic pressure. The flexible casing is formed of a textile fabric. The fabric encased rollers each have openings through their walls, the film treating bath liquid fed under pressure to the interior of each roller and then through the wall openings. The flexible textile casing thereby expands, to produce squeezing force on the photographic material being processed as the material passes between a rigid roller and its associated textile encased roller.

    Abstract: Apparatus for applying bronze powder to adhesive-coated portions of one side of a running web of cigarette paper has a magazine for a supply of bronze powder and a feed screw which draws powder from the magazine and delivers some of the withdrawn powder into a chamber for a transfer wheel whose peripheral surface applies powder to the one side of the web. The powder which fails to adhere to the web is returned into the helical groove of the feed screw upstream of the chamber. A cylindrical sleeve which surrounds the feed screw has an outlet located downstream of the chamber and serving to return into the magazine such powder which is transported beyond the chamber. The sleeve has a longitudinally extending slot for a brush whose bristles extend into the helical groove of the feed screw to prevent agglomeration of powder in the groove.

  • Patent number: 4223633
    Abstract: This invention is an improved applicator for coatings. It is particularly useful for applying hot-melt adhesives in the manufacture of corrugated board. The applicator consists of an apertured manifold from which adhesive flows in parallel ribbons onto a transfer roll. This, in turn, prints it on the tips of the flutes at the single facer or double backer. The manifold is center fed and is equipped with motor-driven, axially adjustable pistons to adjust the width of adhesive spread to the width of surface being coated or bonded. An air purge system operating from within the pistons effectively removes any residual material from the orifices when the pistons are advanced toward the center of the manifold. This prevents plugging from adhesives setting up in the unused orifices. The purge system can also be used to clear orifices that become plugged during operation or to completely remove all adhesive from the manifold.

  • Patent number: 4202915
    Abstract: A mechanical plating process in which a work piece is plated without the necessity of tumbling the work piece in a barrel. A plating member having a plurality of plating elements is positioned with the plating elements adjacent a surface to be plated. Void spaces between the plating elements form reservoirs for liquid plating medium, containing a carrier liquid and plating metal particles. The liquid plating medium is supplied to the work area and to the reservoirs formed by the void spaces. A mechanical plating layer is formed by the plating metal particles by moving the plating member over the work surface with the plating elements, such as bronze wire elements, urged against the work surface. Additional plating medium is supplied to the work area and to the reservoirs during the plating operation to build up an adherent, mechanically applied, metal coating. The plated metal particles are preferably supplied to the work zone in flocculated form.

  • Patent number: 4183321
    Abstract: In a finger slotting and glue applying machine, random length studs, free from blemishes and having precisely squared ends, are advanced edgewise on a conveyor with their right ends (as viewed from the delivery end of the conveyor) aligned, past a set of slotting saws for uniformly slotting the right ends of the studs. The studs are then shifted to align their left ends and advanced past a second set of slotting saws for uniformly slotting the left ends of the studs. The studs then have adhesive applied in the left end slots and are then discharged at the introductory end of a machine which advances the studs lengthwise, interfitting and adhesively uniting successive studs end to end for producing blemish-free composite studs or beams which may be cut into any chosen length or lengths. The present invention has to do with limiting the regulating, the feeding and application of the glue to the slotted left ends of the studs and with the clean recovery and return to the source of surplus glue.

  • Patent number: 4046931
    Abstract: A coating material such as a high viscosity, low solvent content paint is applied to metal strip by means of a coater which comprises a soft-covered take-up roll which draws coating material from a reservoir and coacts with a hard metering roll (from which excess coating material is continuously removed by a doctor blade), to form a metered film on the surface of the take-up roll. The metered film is transferred to a small diameter hard transfer roll from which it is in turn transferred to a soft covered applicator roll, by which it is applied to the strip. At each line of contact between two rolls or between the applicator roll and the strip the mutually contacting surfaces travel in opposite directions (i.e., the rolls all rotate in the same sense). Preferably the peripheral speed of the applicator roll is greater than that of the transfer roll, which is greater than that of the take-up roll, but the strip speed is preferably lower than that of the applicator roll.
