A method of coating a membrane having a first side and an opposite second side and carried with its second side adhering to a backer film is provided. The method includes coating the first side of the membrane with a catalyst ink or slurry with the second side adhering to the backer film and curing the coating on the first side. The backer film is then removed to expose the second side of the membrane which is fed onto a vacuum conveyor with the coated first side facing the conveyor. The second side of the membrane is then coated with a catalyst ink or slurry and the coating on the second side cured after which the membrane is removed from the vacuum conveyor.

A cylinder is usable, in particular, for aligning magnetic of magnetizable particles, which are contained in a coating medium that is applied to a first side of a web-like or a sheet-like substrate, which cylinder, in the region of its outer circumference, has a plurality of elements effecting a magnetic field, magnetic elements for short. The magnetic elements are arranged in or on a plurality of ring elements that are spaced axially apart from one another and that are positionable in the axial direction on a shaft, in or on which ring elements, in turn, a plurality of magnetic elements are respectively arranged one after the other in the circumferential direction. At least two adjacent ring elements, each have a covering element, forming a part of the cylindrical lateral surface of the cylinder and extending in the circumferential direction, at least over the circumferential region populated with magnetic elements. The covering elements of two ring elements adjacent to each other have, on their sides facing each other in the axial direction, a plurality of projections alternating in the circumferential direction with recesses and offset in a circumferential direction in such a way that, during a relative movement of the two ring elements towards each other, the projections on the covering element of one ring element engage, in the manner of teeth, in corresponding recesses of the other ring element, and, as seen in the circumferential direction, can overlap. A security paper printing machine, having such a cylinder, is also disclosed.

There is provided an embossed film in which the frequency of loss of concavities is smaller, the embossed film including: a film main body; and a plurality of concavities formed on a surface of the film main body. A diameter of an opening surface of the concavity is larger than a visible light wavelength, an arrangement pattern of the concavities has periodicity along a length direction of the film main body, and the difference between the rate of loss of concavities in one end portion of the film main body and the rate of loss of concavities in the other end portion of the film main body is 10 ppm or less.

This invention relates generally to flocked articles and methods for making the same, more particularly to flocked products having a silicone adhesive and methods for making and using the same.

An apparatus and process for the delivery of material to rolls of a laminator is disclosed.

A thermoplastic prepreg includes a web or mesh of fibers in which the web or mesh of fibers includes chopped fibers. The thermoplastic prepreg also includes a thermoplastic material that fully impregnates the web or mesh of fibers so that the thermoplastic prepreg has a void content of less than 5%. The thermoplastic material is polymers that are formed by in-situ polymerization of monomers or oligomers in which greater than 90% of the monomers or oligomers react to form the thermoplastic material. The thermoplastic prepreg includes between 5 and 95 weight percent of the thermoplastic material and the chopped fibers that form the web or mesh of fibers are un-bonded.

An apparatus for applying an ultraviolet coating includes: a substantially vertically oriented frame; a first roll rotatably attached to the first side of the frame; a second roll rotatably attached to its second side; multiple nozzles disposed on the first side, above the first roll; a motor coupled to the second roll; an ultraviolet coating fluid reservoir disposed above, and coupled to, the nozzles, thereby providing the nozzles with the ultraviolet coating fluid; and an air compressor coupled to the nozzles, thereby providing the nozzles with compressed air. The ultraviolet coating fluid is provided to the nozzles solely via a gravity feed from the reservoir. In use, the motor causes sheet material, initially wound around the first roll, to advance up and over the frame and then wind onto the second roll, as the ultraviolet coating fluid is sprayed onto the sheet material by the nozzles.

A system for processing a product includes a curing chamber, a light source, and a reflective surface. The curing chamber has input and output openings to permit the product carrying a curable material to move therethrough. The curing light source generates a first curing light beam directed from the curing light source to a first portion of the product for curing the curable material carried on the first portion of the product within the curing chamber. The reflective surface directs a second curing light beam from the reflective surface to a second portion of the product for curing the curable material carried on the second portion of the product within the curing chamber. The second portion of the product is inaccessible by the first curing light beam.

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.

A coating head includes a coating device and at least a first flexible blade that is capable of being shaped into contact with a solvent-containing film on a substrate upon pressing the first flexible blade against the film, thereby providing contact between the blade and the film over a contact distance when the coating head is drawn over the substrate. The coating device and the blade are separated by a spacing distance such that partial loss of solvent occurs from a starting film formed on the substrate by the coating device as the coating head is drawn over the substrate, the partial solvent loss forming the solvent-containing film. A method of producing a film having a hierarchical structure includes drawing a coating head across a substrate to form on the substrate via the coating device a starting film including a solvent and a material for forming the hierarchical structure.
