The number of product layers: It can realize automatic multi-layer and multi-angle laying. Three sets of independent weft laying mechanisms, servo control, can realize any angle of weft laying between-30 ° and + 30 °. Comb/looping mechanism: grooved needle bed, needle core bed, settling bed, 2 bars, 1 ST needle bed, all looping mechanism needle beds adopt constant temperature control system. Drawing device: Servo control, roller continuous rotation, driven by sprocket mechanism. The speed is controlled by the main control system. It can realize the direct arbitrary change of fabric stitch from 0.5-5.5 mm
