Product Introduction
Paper Machine Rolls are full-series core matching rollers for all kinds of paper machines, coating machines and extrusion lamination machines, including stone rolls, rubber covered rolls, water-cooled composite steel rolls, metering coating rolls, paper guide rolls, press rolls, Yankee dryer rubber rolls, doctor rolls and other roller products. Widely applied on fourdrinier paper machines, crescent tissue machines, white board coaters, plastic-free coating machines and extrusion lamination machines, they realize core processes such as web conveying, press dewatering, coating metering, composite laminating and drying guiding. Customizable roll surface material, diameter, length, hardness and internal water cooling/heating channels are available, featuring high wear resistance, corrosion resistance and dimensional precision, suitable for 24-hour high-speed continuous papermaking & coating mass production.

Core Advantages
One-stop supply of full-series rollers matching complete paper, coating and lamination lines, bulk supply for machine manufacturers and old roller renovation service to cut customer comprehensive procurement cost;
Precision CNC machining + high-speed dynamic balance correction delivers high surface precision for 100m/min high-speed lines, flat web running free of transverse lines, deviation and stretching to improve finished paper quality;
Special medium-resistant covering technology prevents rubber peeling & bulging, dense wear-resistant stone roll and anti-adhesion steel roll adapt long-term working condition of various corrosive media including calcium carbonate, thermal, plastic-free bio and PE lamination coating;
Customizable internal cooling & heating circulation channel with tiny roller surface temperature difference stabilizes coating, pressing and composite process parameters for uniform coating weight and consistent dewatering performance;
Flexible non-standard full-size customization of roll length, diameter, rubber hardness and shaft structure, compatible with equipment for white board, thermal paper, plastic-free food paper, tissue and industrial board;
Long wear-resistant service life greatly reduces production downtime for roller replacement and raises comprehensive equipment operating rate, supporting 24-hour continuous papermaking & coating mass production.
