Example implementations relate to selectively deflecting substrates. One example implementation includes an apparatus to selectively lift a part of a substrate away from a transfer member when the substrate is advancing in a substrate coating system relative to the transfer member, such that, across a width of the substrate, a first part of the substrate is coated by the transfer member and a second part of the substrate, that is lifted by the apparatus, remains uncoated.

A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

Disclosed are reel-to-reel coating systems that can be used to form graphene-coated tapes. The coating systems can be modular, self-contained, and sized to allow for benchtop fabrication of coated tape substrates for use in imaging applications. The reels of the coating system can be removable, and adapted to be re-attached to an in-situ scanning electron microscope reel-to-reel imaging system, a reel-to-reel system for sectioning resin-embedded cells and/or tissues with an ultramicrotome, or any combination thereof. In this way, the coater can serve as part of an integrated system facilitating efficient, serial sample processing and imaging.

A method for applying a product by roller on a surface of a substrate (112) transported horizontally with respect to an application head (111, 111′) is discloses. The method includes moving the application head (111, 111′) immediately from a lowered position of the application head (111, 111′), wherein the application roller (122, 122′) applies the product in a predetermined position of the surface of the substrate, to a raised position of the application head (111, 111′), wherein the application roller (122, 122′) does not apply product; or vice versa. An application system using the method for applying a product by roller is also disclosed.

A device for lacquer transfer includes a frame, a transfer roller with a circumferential lateral wall, a drive unit and a lacquer application unit. The lacquer application unit is mounted on the frame and applies lacquer to a work surface of a work piece while the device is moved in an application direction across the work surface. The drive unit drives the transfer roller in a rotation direction about an axis of rotation. An outside contact surface of the lateral wall comprises a plurality of depressions forming a predetermined structure. The transfer roller rolls with the outside contact surface on the work surface of the work piece for transferring the predetermined structure defined by the depressions in the outside contact surface to lacquer previously applied to the work surface by the lacquer application unit.

A device for lacquer transfer is disclosed having a frame, a transfer roller with a circumferential lateral wall, and a nozzle for dispensing lacquer. The nozzle is arranged contactless to or in direct contact with the outside contact surface of the lateral wall for dispensing lacquer into respective depressions in the lateral wall while the transfer roller is rotated about the axis of rotation. The transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface of the work piece. The transfer roller includes a rim and a tire, wherein the rim is mounted to the frame rotatably about the axis of rotation by the first end and extends between a first end and a second end along the axis of rotation, wherein the tire is mounted on the rim and includes the lateral wall.

A fence painting system enables applying a coating to a both the front and back of the fence simultaneously. The system uses spray modules mounted to an anchor to apply the coating. The anchor attaches to the top of the fence and lowers the spray models with an extension device. The modules detect the ground as they descend with a sensor that prevents the modules from impacting the ground.

An adhesive dispensing device, for use in layered object manufacturing (LOM) systems for rapid prototyping of a 3 dimensional (3D) object, for the application of adhesive to a target substrate S defining a layer of a 3D object, the device comprising an adhesive applicator wheel having a plurality of circumferentially spaced apart recesses for receiving adhesive, the adhesive dispensing device being movable relative to the target substrate to deposit adhesive at selected locations thereon, wherein the adhesive dispensing device is mounted for translation relative to the target substrate via a pivot mount configured such that the wheel aligns with its direction of translation relative to the target substrate to deposit adhesive at the selected locations.

A girth weld coating machine has an application head rotatable about a pipeline. A reservoir of coating material is carried on the application head and progressively dispenses coating material on to the girth weld. The coating material is applied to the pipe surface by a roller to spread and distribute the coating over the surface.

A system for lacquer transfer is disclose having a device for lacquer transfer. The device includes a frame, a transfer roller with a circumferential lateral wall, and a slit nozzle for dispensing lacquer. The slit nozzle is connected to the frame. An outside contact surface of the lateral wall includes several depressions. The transfer roller is mounted rotatably to the frame. The slit nozzle is arranged contactless to or in direct contact with the outside contact surface of the lateral wall for dispensing lacquer into respective depressions in the lateral wall while the transfer roller is rotated. The transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface.
