Described is a device (10) for applying an adhesive (C). The device (10) comprises at least one rotary gluing member (21, 31) designed to transfer to a mass of adhesive (C) towards a surface to be glued (S) and a plurality of rotating distributor members (51a-g) susceptible to being interposed, in operation, between the gluing members (21, 31) and the surface to be glued (S). The plurality of distributor members (51a-g) comprises a first portion of distributor members (51b, 51d, 510 susceptible to make contact with the gluing member (21, 31) and a second portion of distributor members (51a, 51c, 51e, 51g) susceptible to remaining spaced from the gluing member (21, 31).

A fluid for application onto a substrate is provided in a cavity of a hollow cylindrical application roller that has porous roller wall. Before reaching the transfer point to the substrate, fluid is regionally selectively pushed back away from the outer shell surface of the application roller, into the porous roller wall, by a knockback pressure, in order to regionally selectively produce the effect that, at the transfer point, fluid is located at the outer shell surface of the application roller or no fluid is located at the outer shell surface of the application roller. A regionally selective application of fluid onto a substrate may thus be efficiently produced.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

The invention relates to a device for applying a hot-melt to a web of material. The device includes a driven roller and a nozzle with a nozzle channel arranged adjacent the driven roller for supplying a hot melt through the nozzle channel to the surface of the roller. The invention also relates to a combination of a device according to the invention and a web of material, which web of material is guided along the driven roller and wherein the nozzle channel exits in front of the nip of the web of material and the driven roller.

A layered object manufacturing (LOM) system and method that provide controlled application of an adhesive onto multiple layers of a paper substrate to effect generation of a three dimensional object. The LOM system includes an adhesive reservoir, an adhesive dispenser, a paper feed mechanism, and a substrate grabber. The dispenser dispenses the adhesive from the reservoir onto the paper substrate at a build location. The paper feed mechanism feeds individual sheets of paper. The substrate grabber transports the sheets from the paper feed mechanism to a build object location to form layers of the paper substrate. The method successively binds individual paper sheets to one another using a water based adhesive applied to specific locations on each individual paper sheet. The method also includes separating scrap material from the three dimensional model and discarding the scrap material.

A coating system for applying a coating to a substrate that can be part of a wall assembly. The system includes a positioning stage and an end effector coupled at a distal end of the positioning stage, the end effector configured to apply coating to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the end effector and positioning stage to perform at least one coating task that includes applying coating, via the coating the end effector, to one or more substrate pieces, the generating based at least in part on obtained target surface data; and drives the end effector and positioning stage to perform the at least one coating task.

In a roller transfer application method for a hot-melt adhesive, a coater head having a slot in a direction towards an axis center of a pattern roller is provided to face a pattern surface of the pattern roller; and by supplying hot-melt adhesive, which is supplied from a hot-melt adhesive supply device, in a thin-film state to a pattern top surface of the pattern roller, thin-film hot-melt adhesive is thus only supplied to the top surfaces of protrusions of the pattern roller. By opening an on-off-type hot-melt adhesive supply control valve, which is attached to the coater head, at a timing that an adhesive opening (the slot) on the bottom surface of the coater head faces application zones on the pattern surface of the pattern roller, the hot-melt adhesive is supplied only to the top surfaces of the pattern roller protrusions.

Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.

An anilox roller and a coating apparatus are provided. The anilox roller includes a roller body and an annular boss formed on a surface of the roller body. The annular boss extends in a circumferential direction of the roller body. The annular boss includes a circumferential surface, a first side surface, and a second side surface. The first side surface and the second side surface face each other in an axial direction of the roller body. The circumferential surface connects the first side surface and the second side surface, and the circumferential surface includes an anilox region having an etched anilox. A first blank region without an etched anilox is arranged between the anilox region and the first side surface.
