A lamination method, includes: a first coating step of applying any one of a main agent M and a curing agent H of a two-component curable adhesive as a coating liquid to a first web W1; a second coating step of applying the other one of the main agent M and the curing agent H as a coating liquid to a second web W2; and a bonding step of bonding a coating liquid-coated surface of the first web W1 and a coating liquid-coated surface of the second web W2, and of combining the main agent M and the curing agent H to increase a molecular weight. In addition, in the first coating step and the second coating step, the main agent M or the curing agent H is applied by a gravure coater.

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 method of depositing a fluid onto a substrate. The method can include the steps of: providing a substrate; providing a fluid; providing a rotating roll comprising an exterior surface wherein the rotating roll rotates about the central longitudinal axis and an exterior surface defines an interior region; providing a vascular network to supply the fluid from the interior region to the exterior surface of the rotating roll in a predetermined path; transporting the fluid to the vascular network; controlling the flow of the fluid to move the fluid at a predetermined flow rate to at least one of the at least two fluid exits; and contacting the substrate with the fluid.

A unit for spreading an adhesive onto a moving film, includes at least one pair of abutments (11) upon which is mounted a first pick-up roller (12) for collecting a quantity of adhesive from a collection zone (13), a second roller (14) that rotates in contact with the first roller (12), intended to receive the quantity of adhesive, and a third roller (15) that rotates in contact with the second roller (14), wherein the abutments include at least one fixed portion (19) and one moving portion (20, 21) that can be firmly connected to the fixed portion, the moving portion being configured: to house a tank (17) in which the adhesive collection zone is found, or to house an additional fourth roller (18) positioned at a given distance from the first roller, the collection zone being located in the upper space between the first and the fourth roller (12, 18).
