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, 51f) 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).

An applicator is disclosed for applying sealant to a moving substrate. The applicator includes a wheel having a periphery. A plurality of spaced apart footprints extends around the periphery of the wheel and each footprint has a sealant receiving feature. A reservoir is provided for containing a supply of sealant to be applied to the moving substrate. The wheel is rotatably mounted at least partially in the reservoir such that as the wheel rotates, each of the spaced apart footprints repeatedly moves through a supply of sealant in the reservoir to pick up a charge of sealant, around one side of the wheel toward the moving substrate, adjacent the moving substrate to transfer the sealant charge to the substrate, and around the other side of the wheel back toward the supply of sealant. At least one stop is formed on each of the footprints for inhibiting sealant picked up by the footprint from being urged rearwardly on the footprint by high speed rotation of the wheel. A backstop may be formed at a trailing end of each footprint and mid-stops may be formed between a leading end of each footprint and the trailing end.

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.

Described is a roller for the automatic application of at least one adhesive on a sheet for mattresses, which makes it possible to optimise the time needed for processing and the precision of the distribution of adhesive on the sheet in relation to the desired pattern, eliminating the waste of adhesive.

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.
