Abstract: Methods and apparatuses herein may provide for the application of viscous fluids, such as adhesives, in pre-determined patterns to an advancing substrate. The fluid application apparatus may include a slot die applicator and a substrate carrier. The substrate carrier may include one or more pattern elements and may be adapted to advance the substrate past the slot die applicator as the slot die applicator discharges adhesive onto the substrate. In operation, the substrate is disposed on the substrate carrier; the substrate carrier advances the substrate past the slot opening of the slot die applicator. In turn, the substrate is intermittently compressed between the slot die applicator and the pattern surface of the pattern element. As the substrate is intermittently compressed, adhesive discharged from the slot die applicator is applied onto the substrate in an area having a shape substantially the same as a shape defined by the pattern surface.

Abstract: A method for intermittently applying thin-film coatings is realized, by which a coating of extremely thin film reduced to 20 ?m or less in thickness is deposited intermittently with high productivity and at the same time, the trailing coating edge of the thin film is formed in a highly accurate shape having good linearity. This is achieved as follows. A band-shaped substrate (1) traveling in one direction is kept looped over a stationary reference-roller (4) and a movable actuation roller (7), and is brought into contact with an application roller (19) which carries a coating agent (18) on its circumferential surface and rotates in a direction opposite to the direction of travel of the substrate (1). The actuation roller (7) is moved to come into or out of contact with the substrate (1) with a predetermined timing.

Abstract: A machine for confining cigarettes or packets of cigarettes in converted blanks of paper, cardboard or the like employs a paster serving to apply adhesive to selected portions of successive blanks of a series of moving blanks. In order to compensate for wear upon and/or for misalignment of the paster and/or a back support for the blanks during application of adhesive, the back support is adjustable relative to the paster and/or vice versa in several directions. Such adjustability ensures predictable application of adhesive, such as hot melt, to predetermined portions of the blanks. The back support and/or the paster is or can be biased to a predetermined position relative to the path for the moving blanks.

Abstract: The distance between a D-roll and a C-roll is switched at proper time intervals between two stages in which the distance is larger or smaller. A thicker coating layer on the C-roll with the thickness controlled by the larger distance between the D-roll and the C-roll is transferred onto a base sheet in a condition in which the C-roll and a B-roll are in contact with each other with the base sheet interposed therebetween. The distance between the C-roll and the B-roll is increased when a thinner coating layer on the C-roll with the thickness controlled by the smaller distance between the D-roll and the C-roll reaches a transfer position, so that the coating layer is not transferred onto the base sheet. A local increase of the amount of the coating material applied at the end of a coating area can be prevented, and the thickness of the coating material applied can be controlled to be constant with high accuracy over the entire coated area.

Abstract: Investigations have shown that curtailing the entry of air between the coater backing roll (3) and the web (5) being coated can offer a significant reduction in the number of uncoated blotches. By virtue of preventing the occurrence of such coat defects, the rotational speed of the kiss roll (2) in kiss roll coaters can be reduced. The invention is based on pressing the web (5) being coated against the backing roll (3) from the opposite side of the web (5) relative to the backing roll (3) at a point preceding the nip between the kiss roll (2) and the backing roll (3), whereby air is prevented from entering between the web (5) and the backing roll (3). The means employed for pressing the web (5) against the backing roll (3) is an air jet to avoid imposing additional stress on the web.

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: 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.

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.
