A device is disclosed including a frame, a transfer roller with a circumferential lateral wall, a drive unit, a slit nozzle with a muzzle end for dispensing lacquer, and a deformation unit. The slit nozzle and the deformation unit are each connected to the frame, and an outside contact surface of the lateral wall includes several depressions, the transfer roller is mounted rotatably about an axis of rotation at the frame. The drive unit is configured to drive the transfer roller in a rotation direction of the transfer roller, such that the lateral wall continuously passes through a first angular range and the second angular range, each fixed to the frame. The deformation unit is arranged to elastically deform the lateral wall resulting in a respective first deformation section of the lateral wall passing through the first angular range and a respective second deformation section of the lateral wall passing through the second angular range.

System and device for a lacquer transfer

A device for lacquer transfer is disclosed having a frame, a nozzle with a dispensing end for dispensing lacquer, and a transfer roller with a circumferential lateral wall, a circumferential outer contact surface of the lateral wall comprises several depressions, wherein the nozzle and the transfer roller are arranged such that lacquer is dispensable from the dispensing end onto the outer contact surface and into the depressions, wherein the transfer roller is configured to roll with the outer contact surface on a work surface of a workpiece for transferring the lacquer from the outer contact surface and from the depressions to the work surface of the workpiece. A first hardening unit is formed as a UV-light unit configured for partially hardening the lacquer in a contactless way by emitting UV-light, the first hardening unit is arranged within an interior space defined by the transfer roller. The lateral wall of the transfer roller is transparent for UV-light, and the first hardening unit is arranged such that UV-light is emittable towards the work surface in a first operational area of the work surface to partially harden the lacquer in the first operational area.

The transfer roller is mounted rotatably about an axis of rotation to the frame, wherein the slit nozzle is arranged for dispensing lacquer into respective depressions in the lateral wall while the transfer roller is rotated about the axis of rotation, wherein 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, wherein the slit nozzle at its muzzle end includes an upper lip and a lower lip as well as a slit between the upper and lower lips for dispensing lacquer.

A device for a lacquer transfer includes a frame, transfer roller with a circumferential lateral wall, drive unit for rotating the transfer roller, and slit nozzle with a muzzle end for dispensing lacquer. The slit nozzle includes a first nozzle-part, second nozzle-part and deformation unit. The deformation unit is attached to the first nozzle-part, the lateral wall passing in a rotation direction subsequently the deformation unit and the muzzle end during transfer unit rotation. The lateral wall of the transfer roller is deformed by the deformation unit in the radial direction resulting in a deformation section of the lateral wall in the rotation direction behind the deformation unit, the muzzle end of the slit nozzle arranged for dispensing lacquer into depressions of the lateral wall. The transfer roller can roll with the outside contact surface on a work surface of a work piece for transferring lacquer from the depressions to the work surface of the work piece.

Lacquer transfer device

A device for a lacquer transfer includes a transfer roller mounted at and rotatable relative to a frame. The roller includes a cylindrical support-body, first ring-element, second ring-element, and a tire including a middle-section forming a circumferential outer contact surface with depressions, the roller configured to roll with the outer contract surface on a work surface of a workpiece for transferring lacquer from the outer contact surface and the depressions to the work surface. The tire includes two annular end-sections attached to a cylindrical outer shell of the support-body resulting in two axially separated and circumferentially extending connections, the tire, connections, and outer shell of the support-body being fluid-tight. The first and second ring-elements are in the first cavity seated on the support-body at a distance in an axial direction of the roller from one another and the middle-section of the tire between the first and second ring-elements is prestrained in the axial direction.

A device for lacquer transfer is disclosed including a frame, a transfer roller with a circumferential lateral wall, and a nozzle for dispensing lacquer, wherein the nozzle is connected to the frame, wherein an outside contact surface of the lateral wall comprises several depressions, wherein the transfer roller is mounted rotatably about an axis of rotation at the frame, wherein 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, and wherein 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.

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 device for lacquer transfer includes a frame, transfer roller with circumferential lateral wall, nozzle for dispensing lacquer, and hardening unit, the hardening unit formed as a UV-light unit for hardening the lacquer in a contactless way by emitting UV-light, and is within an interior space defined by the transfer roller. The lateral wall of the transfer roller is transparent for UV-light, and the hardening unit is arranged such that UV-light is emitted towards the work surface upon which the lateral wall of the transfer roller rolls, to harden the lacquer after it being transferred to the work surface. Using the device, lacquer transfer can occur from the transfer roller to the work surface more reliably. The device includes a light shield between the hardening unit and outside contact surface with at least a portion of the outside contact surface provided with lacquer is shielded from UV-light emitted from the hardening unit.
