An electrode mixture paste (5) is applied on both sides of a strip of core material (1) made of porous metal sheet that is running along its lengthwise direction. The paste-coated core material (1) is pressed with press rollers (15a, 15b) alternately from opposite sides once or more, after which the paste-coated core material (1) is passed through the gap between a pair of scraper tools (16a, 16b) to adjust the coating thickness of the paste (5), while the position of the core material (1) is restricted with comb-shaped projections (17a or 17a, 17b), so that, even though the projections (17a, 17b) are distanced from each other sufficiently to allow weld points of the core material (1) to pass through, the coating thickness is precisely regulated. Therefore, a method of applying an electrode mixture paste is realized, with which coating thickness is precisely adjusted and, even in a continuous production process in which core materials are connected together by welding, production failures due to weld points being stuck are prevented.

A method for impregnating a flat, fibrous substrate penetrated by a low viscosity, fluid synthetic resin, the substrate web 1 being preheated by known device 2 and thereupon being made to pass over a friction roller 3 which is heated where called for and which is uniformly wetted at its surface 6 with the low viscosity, aqueous synthetic resin solution based on an aminoplastic resin, substantially a melamine resin 5 or based on a phenolformaldehyde resin 5' present in a bath, the low viscosity, aqueous synthetic resin solution being uniformly heated and at least part of it penetrating the surface of the substrate web 1, whereupon the substrate web 1 loaded with synthetic resin is fully impregnated in the bath 4. Next this substrate web soaked with synthetic resin is made to pass through a metering device 7 and a drying channel 8 wherein the solvents of the aqueous, synthetic resin solution absorbed by the substrate are extensively evaporated in a flow of hot air and thereupon this substrate is cut to size in cutting device 9 into flat pieces 10 and is stacked in stacking device 11. The composites 10 are suitable to manufacture decorative cover layers, industrial insulating materials and core-layers of decorative molded laminates.

A method for continuously scouring and blooming an advancing pile carpet includes first wetting the pile side of the carpet with hot water spray, and then immersing the carpet in a first tank containing hot water. The carpet is then advanced past a high pressure spray positioned above the first tank which directs a high impact spray at the pile to remove the finish on the pile and provide the initial blooming or bulk development of the yarn. The carpet then passes through a second tank containing hot water and past a final spray which rinses away any residual finish and provides the final blooming. Water to supply the high pressure spray is pumped from the second tank. The first and second tanks are interconnected so that water can flow from the first tank into the second tank to supply the pump. Facilities are also provided to remove the finish from the water in the first tank.

A continuously connected textile fabric having seams at predeterined intervals is fed along its length to a succesive processing apparatus. The apparatus includes a plurality of squeezing rollers and a textile feeding path comprising a plurality of processing liquid tanks arrayed in turn, and seam detecting limit switches are provided at the places of the squeezing rollers, with the distance of the path between adjacent limit switches being chosen to be almost the same as the interval of said seams. In a state where the seams are positioned at the squeezing rollers, and thus at the limit switches, all the squeezing rollers are driven in a forward direction at once and after a predetermined relatively large forward travelling amount, they are driven in a backward direction by a predetermined relatively small backward travelling amount, the difference between the forward and backward travelling amounts being chosen to be approximately equivalent to a distance of the interval of said seams divided by an integer. During the final backward driving operation in one full cycle of the forward and backward reciprocating operations for the number of times of said integer, said limit switches are enabled and according to the order of arrival the seams drive the limit switches to bring the squeezing rollers to a stop. When all the squeezing rollers are brought to a stop, the limit switches are disabled to repeat again said operation cycle. Thus, during the reciprocating operation for the number of times of said integer, the textile fabric is fed in the forward direction by the interval of said seams while being processed, and the slip produced therebetween is compensated by the stop of every squeezing roller responding to each of the limit switches.

A method and apparatus for treating textile cord on a continuous basis where the cord is sequentially treated by application of aqueous solution passed through a squeeze roll station, passed through a pull roll station and then to a drying operation. The applied liquid is additionally removed from the cord by specially positioned and designed elastomeric squeeges located in the squeeze roll area and the pull roll area.

Method and apparatus for applying foam to an open-weave substrate. The apparatus contains angled shear strips to shear the foam positioned above a foam outlet. The shear strips, enclosed at each end, define a chamber above the foam outlet having open top and bottom sides for sequential contact of both sides of the substrate with the foam as the substrate travels across the outlet and both open top and bottom sides of the chamber.
