A device for lacquer transfer with a frame, transfer roller with a circumferential lateral wall, and nozzle for dispensing lacquer, the nozzle connected to the frame, wherein an outside contact surface of the lateral wall includes depressions. The transfer roller is mounted rotatably about an axis of rotation to the frame, the nozzle arranged for dispensing lacquer into depressions 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 lacquer from the depressions to the work surface, the depressions formed and distributed over the outside contact surface in a predefined pattern having a main orientation direction. Efficiency of lacquer transfer can be increased as the pattern is arranged such that the main orientation direction extends other than perpendicular to the axis of rotation of the transfer roller.

An apparatus for coating carpet webs in a coating apparatus with varying adhesives includes a controller, one or more sensors for detecting a volume of a puddle of the adhesive pooled in front of an application roller, and an electronic valve in fluid communication with each of a plurality of mixers. The electronic valve directs flow of the adhesive from any of the mixers to the coating apparatus. To switch from one of the adhesives to new adhesive as a next carpet web passes through the coating apparatus, the controller calculates a remaining length of the carpet web that can be coated with the adhesive in the puddle of adhesive based on the volume of the puddle, so that the puddle of the adhesive coats the carpet web, and then proximate a seam to the next carpet web, the new adhesive begins to coat the next carpet web.

A system and method of scanning an environment and acquiring an image is provided. The system includes a mobile device having a camera and a first position indicator. A scanner having a light emitter and a light receiver is provided. The scanner determining coordinates of surfaces in an environment in response to emitting light with the light emitter and receiving light with the light receiver, the scanner having a second position indicator. One or more processors are provided that determine the position of the mobile computing device and transmits the data between the scanner in response to the first position indicator engaging the second position indicator.

A system for lacquer transfer is disclose having a device for lacquer transfer.
