The present invention relates to a spreading machine for roller leather finishing. The machine includes a drawing cylinder and an engraved spreading cylinder. The drawing cylinder acts as a driving roller for a rubber conveyor belt wound between the driving roller and an idle roller. The drawing cylinder has a conveying surface and a rubber layer. In each operating configuration, the conveying surface of the rubber conveyor belt is tangent to the engraved spreading cylinder in a point of tangency (P), and the idle roller has a leather-detachment roller having a diameter within the range of 10 and 80 mm.

Roller coater (1) for applying paint to mainly flat panels (8), comprising, in the direction of conveying of panels: a feed roller (9), preferably coupled to a contrast roller (39); an application head for applying paint, comprising an applying roller (3) and a dosing roller (11), said applying roller being preferably coupled to a contrast roller (33); a conveyor (12) for the panels (8) to be painted, preferably in the form of a closed belt conveyor;

characterized in that said applying head (9) is covered by its own cover (5), said application head is covered by a preferably vertical cover (2) and a preferably horizontal cover (6), which covers are removable, said applying roller being rotatably mounted on rotation supports (15) placed at its two ends, which are disengageable from said applying roller, said applying roller being withdrawable from its working position and distanceable from said working position in the application head through a withdrawing path providing an initial translation for disengaging it from its rotation supports in the direction of the feed roller (9) and a successive translation in a lifting direction, i.e. distancing it from said conveyor (12), there being provided a lifting member of said roller, preferably coupleable to the ends of said applying roller, the interaxis distance between said feed roller (9) and said applying roller (3) is at least equal to the length of the initial translation path for disengaging the applying roller from the rotational supports (15), and lower to the minimal length of the panels paintable with said roller coater (1).

A coating system and method including a web path moving a substrate past a contacting element including a distribution manifold having a cavity, and a multiplicity of needle tubes in fluid communication with the cavity, the needle tubes each having a needle tip dispensing a coating material towards a point of contact between the substrate and the contacting element. In some embodiments, the distribution manifold separates into a manifold containing the internal cavity, and a removable cartridge having the plurality of needle tubes. The coating system and method can be used to apply a pre-metered coating material to the substrate.

A device for applying adhesive to a substrate, having an application roller that is rotatable about an axis, an installation for dispensing adhesive to a circumferential area of the application roller, a dispensing region of the application roller for dispensing adhesive from the application roller, and having a doctor blade, wherein the dispensing region for adhesive in the rotation direction of the application roller is located behind the installation for dispensing the adhesive to the application roller and ahead of the doctor blade. In such a device it is provided that the application roller is rotatable about a vertical axis and the excess adhesive wiped by the doctor blade reaches a collection installation that is located below the doctor blade. In a method for applying adhesive to a substrate, excess adhesive that has not been applied to the substrate is disposed of.

A method for applying a product by roller on a surface of a substrate (112) transported horizontally with respect to an application head (111, 111′) is discloses. The method includes moving the application head (111, 111′) immediately from a lowered position of the application head (111, 111′), wherein the application roller (122, 122′) applies the product in a predetermined position of the surface of the substrate, to a raised position of the application head (111, 111′), wherein the application roller (122, 122′) does not apply product; or vice versa. An application system using the method for applying a product by roller is also disclosed.
