Patent number: 5476546Abstract: An apparatus for applying a liquid lubricant in a pattern to a face of a sheet workpiece has a support frame through which the workpiece is transported in a travel direction substantially parallel to its face, a plurality of axles in the frame extending along respective axes generally perpendicular to the direction and individually displaceable generally perpendicular to the direction and to the respective axes, and respective liquid-pervious rollers journaled on the axles about the respective axes. A liquid lubricant is fed to the rollers and respective actuators connected between the axles and the frame displace the respective rollers perpendicular to the direction and to the respective axes into and out of contact with the workpiece as same passes in the direction through the frame. A controller connected to the actuators individually controls and operates same to apply the liquid lubricant in the rollers to the workpiece in a predetermined pattern as the workpiece passes through the frame.Type: GrantFiled: September 30, 1993Date of Patent: December 19, 1995Assignee: Firma Zibulla & Sohn GmbH Raziol-SchmierungstechnikInventor: Georg G.

Patent number: 5413806Abstract: A continuous strip coating machine has top and bottom applicator rolls and a backup roll adjacent the top applicator roll. A lift roll to lift the strip of material and thus vary the angle of wrap of the strip about the bottom applicator roll is provided. The use of the lift roll in turn varies the pressure between the strip and the roll and thus the thickness of the coating applied to the strip bottom. Thickness may be measured indirectly by measuring pressure of the strip on the applicator roll. Thickness may also be measured directly. Oscillations of the strip in a drying oven may also be sensed and compensated for. Feedback control is used with the thickness measuring techniques to control the coating thickness by varying angle of wrap, relative speed between the applicator roll and strip, and/or nip pressure between the applicator roll and a transfer roll that transfers coating material to the applicator roll.Type: GrantFiled: February 1, 1993Date of Patent: May 9, 1995Assignee: Hunter Engineering Company, Inc.Inventor: Curt Braun

Patent number: 5378281Abstract: An apparatus is provided for pretreating plastic sheets having poor adhesive properties, with a primer treatment. The primer treatment includes a sheet conveyor for conveying plastic sheets in one direction at a constant speed. A flexible, porous friction member is arranged so as to come into contact with adhesive areas of the plastic sheets. A press confronts the friction member and presses the plastic sheet against the friction member. A primer solution is supplied to the friction member where it is transmitted to the plastic sheet.Type: GrantFiled: September 14, 1992Date of Patent: January 3, 1995Inventor: Yoshiyuki Kamata

Patent number: 5275657Abstract: The present invention relates to an apparatus and a process for applying at least one adhesive component to a honeycomb half-cell structure. The half-cell structure has a plurality of peaks and valleys on each side thereof and a diagonal surface between each consecutive peak and valley. The apparatus comprises a first and second back-up roll and a first and second gravure roll. The first and second gravure rolls are disposed in a bath of a first adhesive component and a second adhesive component, respectively. Each of the first and second back-up rolls includes a plurality of spaced bars. The peaks of the half-cell structure face away from the bars of each respective back-up roll, and the peaks on the other side of the half-cell structure contact each respective first and second gravure roll, so that the first adhesive component contacts the peaks on the one side and the second adhesive component contacts the peaks to apply the first and second adhesive components to the half-cell structure.Type: GrantFiled: November 25, 1991Date of Patent: January 4, 1994Assignee: E. I. du Pont de Nemours and CompanyInventors: Joseph J. Duffy, Birol Kirayoglu, Pui-Yan Lin

Patent number: 5251989Abstract: An apparatus for producing a multi-colored printing ribbon including a first printing station where one or more spaced transfer heads transfer a first color to selected portions of a web of base colored ribbon stock. A second printing station where one or more spaced transfer heads transfer a second color to said web interleaved with the first color to providing a serial, alternating color pattern. Control devices connected to both printing stations insure that the color segments are deposited in proper serial, spaced locations to prevent the colors from running onto each other. Also disclosed is a method for using such multi-colored ribbons to prevent counterfeiting or theft of various documents wherein at least some of the characters to be printed on such documents are printed in a predetermined sequence of colors.Type: GrantFiled: August 10, 1992Date of Patent: October 12, 1993Inventor: Eugene Di Luco

Patent number: 5209040Abstract: A capsule sealing apparatus is provided which includes a capsule supplying device, a slat, a capsule conveyor unit, a capsule sealing device, a plurality of capsule retaining plates, a drying device, and a capsule discharging device. The capsule supplying device intermittently supplies a prescribed number of capsules at a time. The slat includes a plurality of capsule resting slits for individually accommodating the capsules. The capsule conveyor unit linearly reciprocates the slat, during which the capsules are individually accommodated in respective capsule resting slits. The capsule sealing device coats the seams of the capsules with a sealing liquid through the openings at the bottoms of the slits in the slat. The capsule retaining plates receives all the capsules thereon. The drying device vertically circulates the capsule retaining plate with the charged capsules thereon in the horizontal posture so as to dry the sealing liquid applied on each capsule.Type: GrantFiled: July 16, 1992Date of Patent: May 11, 1993Assignee: Nippon Elanco Kabushiki KaishaInventors: Taizo Yamamoto, Masakiyo Inoue, Yoshihisa Kawaguchi

Patent number: 5028457Abstract: An improved roll coating apparatus and method includes a coating roll having a smooth surface for applying a resist, a doctor roll having grooves on its surface for supplying prescribed amount of the resist to the coating roll, and a back up roll which is in contact with the coating roll for conveying a substrate on which the resist is applied to a prescribed direction. Even if there are minute concave portions on the surface of the substrate, the resist is forced to fill the minute concave portions, since the resist is pressed and forced to be applied on the substrate by the coating roll having smooth surface and the back up roll.Type: GrantFiled: August 9, 1990Date of Patent: July 2, 1991Assignee: Dainippon Screen Mfg.
