After years of R & D and practice, Changzhou runfengyuan Textile Machinery Manufacturing Co., Ltd. has successfully manufactured various models of high-speed Tricot and Raschel warp knitting machines. The products have a wide range of changes, high production efficiency and simple operation and maintenance, which can meet different needs and fabric structures. The equipment adopts a new crankshaft connecting rod mechanism optimized by a computer, which reduces the deformation and vibration of parts. The needle bed adopts carbon fibre, which has the advantages of being lightweight, small temperature change and strong rigidity. It is very suitable for high-speed warp knitting machines. All beam shafts adopt a computer-controlled EBC let off mechanism, which can produce pattern tissue with different let off speeds, and the same tissue can have different pattern effects and different densities. The comb bar adopts an integrated mechanism, which is convenient for installation, and the structure tends to be more reasonable. Using EAC electronic take up and winding system, high-quality grey cloth with a uniform coil structure can be woven.
