Abstract: An apparatus for the application of a protective coating to the welded or soldered seam of can bodies. Two driven rolls arranged in tandem or series apply a protective coating, typically in the form of a lacquer, to the seam of the cans or can bodies. One of the rolls covers the actual seam and the other roll covers the region neighboring the seam. Both effective regions of the rolls overlap laterally of the seam at critical locations where the protective coating is to be applied to the seams of the can.

The apparatus comprises a rotatable disc having a surface positioned in a vertical plane and a plurality of mandrels secured to the surface of the disc and projecting horizontally therefrom for supporting the containers. A rotatable painting roll is positioned adjacent the disc for applying paint to the containers. First and second rotatable paint storage rolls are provided, the second paint storage roll being above said painting roll and interposed between the painting roll and the first paint storage roll. The axes of the two paint storage rolls are parallel and in a horizontal plane, and the axes of the painting roll and the second storage roll are parallel and define a plane which is angularly displaced with respect to the horizontal and vertical planes.

Abstract: A plating chamber holds a reducing or inert atmosphere heated to a temperature suited for plating or galvanizing. A pair of power-driven coating rolls are horizontally disposed in the plating chamber, one roll contacting the top surface of a metal strip to be plated and the other contacting the bottom surface. A molten coating metal is continuously supplied so as to form a uniform film of the metal on the peripheral surface of each coating roll. By means of deflector rolls horizontally disposed in the plating chamber, a metal strip heated to a temperature suited for plating continuously travels through the chamber. A surface of the strip becomes plated on contacting the peripheral surface of the coating roll on which the film of the molten coating metal has been formed. The coating rolls can be drawn away from the surface of the strip by shifting the deflector or coating rolls, so that plating can be applied to one, both or neither side of the strip as desired.

Abstract: An apparatus for applying hot melt glue to back surfaces of book blocks, wherein these back surfaces are distributed in fan-like fashion, by means of glueing rollers, two of which are consecutively arranged conically-shaped rollers which are adjustable in their angular setting, whereby the tearing out resistance of the sheet edges is increased. Each glueing roller is supported in an individual glue pan which may be separately pivoted and adjusted in its height. By adjusting of angular setting of the aforementioned two rollers the vertical position of each glue pan may be corrected. This will ensure a uniform and sufficiently large glue layer over the back surfaces of the blocks throughout the entire process of glueing.

Abstract: A laminate composed of a web of carrier material and a thick layer of contact adhesive thereon wherein the thick layer is composed of a series of thin layers of contact adhesive which are bonded together. Methods and apparatuses are disclosed for preparing the laminate. Using such methods and apparatuses, thick layers of contact adhesive may be simply and economically produced.

Abstract: My invention relates to the method and apparatus for printing stripe patterns on the outside surface of cylindrical objects such as glass tumblers with their axes vertical during the printing operation, the stripes being printed substantially circularly about the axis of the cylinder as the center. The cylinder being striped is supported at a printing station for free rotation about its vertical axis. A stripe printing head provided with a stripe printing roller and an ink applicator drum, both rotating about substantially vertical axes, is moved to bring the printing roller in tangential printing contact with the tumbler surface. The printing head includes an enclosed ink (or pigment) supply well adjacent a segment of the perimeter of the applicator drum and means for maintaining the supply well full from a supply reservoir.

Abstract: Labeling apparatus wherein a rotor rotatable about a vertical axis is provided with peripherally spaced suction pads for taking labels presented thereto in vertical positions, moving them by adhesive-applying rolls for application of adhesive thereto and then pressing them into engagement with the side surfaces of containers supported in vertical positions. The adhesive-applying rolls are supported in substantially vertical positions in tangential relation to the rotor and there are adjustably mounted doctor rolls supported in tangential engagement with the adhesive rolls. The surfaces of the adhesive-applying and doctor rolls have mutually interengaged ribs and grooves and adhesive is supplied to the upper ends of the doctor rolls in free flowing streams so as to flow downwardly over the lateral surfaces of the rolls to their lower ends. A tray at the lower ends provides for collecting the adhesive and returning it to a reservoir for reuse.

Abstract: This invention relates to a method and apparatus, for applying a first and second coating to the exterior surface of a can. The apparatus comprises a mandrel rotatably mounted on a pivotable arm, so that pivoting of the arm carries a can on the mandrel to a first position, in which it is held by a solenoid acting upon a portion of the arm, while a first coating means applies a first coating. Thereafter the arm is released for pivoting to a second position where it is held by a second holding means while a second coating means applies a second coating.

In the exemplary embodiment, such apparatus is arranged to perform a two stage coating and printing operation on the outer surface of cylindrical tubes. A rotatable turret includes a first and second series of carriers angularly spaced in first and second arrays around the circumference thereof. Means are provided to index the turret to bring the tubes held in the carriers of the first array to a first operational station for coating, and the tubes held in the second array of carriers to a second operational station for printing.

Abstract: Bookbinding apparatus for applying glue to the backbone edge of collated book sheets conveyed through a gluing station comprises counter rotating applicator rolls for transporting glue from a rectangular glue pot to the backbone the rolls substantially completely spanning the parallel sidewalls of the glue pot so that glue can not flow between the ends of the rolls and the side walls. Doctor blades extend from the ends of the glue pot to respective rolls so as to confine the adhesive below the rolls. One of the doctor blades is linearly retractable from its roll to an extent limited by a linearly adjustable stop which meters a volume of glue carried to the book in direct linear relation to the adjustment of the doctor blade stop.

Abstract: A machine for processing image-wise exposed light sensitive plates comprises processing rollers for agitating developer liquid in contact with the plate as the plate passes through the machine. The plate is urged into contact with the rollers by a plate member which is preferably adjustable and provided with recesses and preferably the developer applied to the plate is filtered developer and is applied by spraying. After developer has been removed, the plate is urged into contact with a roller, dipped in desensitizing solution, by means of, for example, a preferably adjustable second plate member. The desensitized developed plate is then dried before leaving the machine.

More particularly, the filaments are arranged side-by-side in a substantially planar array, at a first location one face of the array is contacted with the liquid finish composition and, then, at a second location spaced apart from the first location the other face of the array is contacted with the same composition. During the contacting at the first and second locations the tension is controlled so that it is in a range in which the contacting applies the composition to the filaments uniformly from filament to filament.
