An apparatus may move a carriage along a rail. The apparatus may include a frame and one or more sets of teeth. A shuttle may translate with respect to the frame. The shuttle may engage with the carriage to translate the carriage in a first direction. The teeth may extend into a carriage recess of the frame. The teeth may allow the carriage to translate within the carriage recess in the first direction. The teeth may inhibit the translation of the carriage within the carriage recess in a second direction.

A printing system is disclosed for thermal transfer printing onto a surface of a substrate. The system comprises a transfer member having opposite front and rear sides with an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which energy is applied by a thermal print head via the rear side of the transfer member to selected regions of the imaging surface to render particles coating the selected regions tacky, and a transfer station at which the imaging surface of the transfer member and the substrate surface are pressed against each other to cause transfer to the surface of the substrate of the particles that have been rendered tacky.

There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.

Provided is an apparatus for cooling a metal material, the apparatus comprising: a spray cooling unit for spraying a cooling medium onto the surface of a metal material; and a spray amount control unit which regulates the rate of passage of the cooling medium sprayed from the spray cooling unit onto the edge region of the metal material, and controls the spray amount of the cooling medium.

A liquid delivery system including a spray nozzle that includes a spray tip. The spray nozzle receives liquid via a liquid supply line. The spray tip of the spray nozzle generates an atomized liquid spray output when the liquid flowing through the spray nozzle passes through the spray tip. The spray nozzle includes a fluid control valve and a flow meter. The fluid control valve controls a flow rate of the liquid dispensed by the spray nozzle. The flow meter determines a flow rate of the liquid dispensed by the spray nozzle. The spray nozzle also includes a housing configured to retain and support the fluid control valve and the flow meter. The liquid delivery system includes a controller that provides feedback and control of the spray nozzle by receiving a flow rate signal from the flow meter and outputting a control signal to the fluid control valve.

The purpose of the present invention is to provide a viscous material application apparatus capable of reliably applying an appropriate amount of a viscous material to a shaft-shaped member. A seal application apparatus (1) is provided with a flexible tubular nozzle (2), which is capable of discharging a sealing agent from an opening (6) formed on the tip thereof, and an actuator (3) for moving the nozzle (2). After or during discharge of the sealing agent by the nozzle (2), the tip of the nozzle (2) moves in the circumferential direction along the outer circumferential surface of a fastener (20), and as the nozzle (2) is stopping the discharge of the sealing agent, the tip of the nozzle (2) moves in a direction away from the outer circumferential surface of the fastener (20).

An apparatus for coating pipes includes a spraying device rotatable around a pipe. The coating apparatus includes a guiding ring mounted around the pipe and a carriage to be mounted on the guiding ring, the carriage being motor driven, the motor being enclosed into the carriage and the carriage including an adjustable device to be detachably mounted on the guiding ring.

Method and system for thermal transfer printing are disclosed. The system includes a transfer member having an imaging surface on the front side, a coating station at which a monolayer of particles made of, or coated with, a thermoplastic polymer is applied to the imaging surface, an imaging station at which electromagnetic radiation (EM) is applied via the rear side of the transfer member to selected regions of the particles-coated imaging surface to render the particles thereon tacky within the selected regions, and a transfer station at which only the regions of the particles coating that have been rendered tacky are transferred to a substrate. The transfer member includes on its rear side a body transparent to EM radiation and on its front side an EM radiation absorbing layer, the imaging surface being formed on, or as part of, the absorbing layer.

A chamber for fluid application to a piece of material (M), such as a web or strip arranged to nm in the chamber (10), has a fluid applicator (2) for fluid application to the material. It further includes an inlet (11a) through which the material is fed into the chamber (10), an outlet (11b) through which the material exits the chamber (10), an outlet passage device (15) arranged at the outlet (11b) and configured to form an outlet fluid sealing of the chamber, and an inlet passage device (16) arranged at the inlet (11a) and configured to form an inlet fluid sealing of the chamber.

A system that applies liquid conditioning agent to at least one of a plurality of sides of an untreated board is provided. One embodiment has an enclosure with a first side having a first aperture and an opposing second side with a second aperture having dimensions that correspond to the width and thickness of the untreated board; a spray applicator system comprising a plurality of spray nozzles located within a chamber and oriented inward, wherein the liquid conditioning agent is sprayed through the spray nozzles onto at least one of the sides of the untreated board as the untreated board passes through the chamber of the enclosure; a plurality of brushes located after the spray applicator system, wherein the liquid conditioning agent is brushed onto the sides of the untreated board, wherein the untreated board enters through the first aperture, and wherein a treated board exits through the second aperture.
