Paper Machine (for Specialty Paper Making)

Huaxia also provides paper machines for the production of specialty paper, included regenerated leather, asphalt paper, grey board, sealing gasket paper and filter paper. The specialty paper is made from the leftover material of various leather, scraps from the buffing machine, waste fibers and more, which are first processed into pulp and then formed into a paper sheet with a width of 0.6-5mm on the fourdrinier table. After this, the paper sheet undergoes dewatering, pressing, drying, polishing, flattening, cutting, winding and packaging in the specialty paper machine.
