Features Special hardening to prolong service life: increases durability and reduces maintenance needs in demanding use. Extrusion type design with lateral movement: can be moved sideways during twill pattern processing to improve pattern alignment and consistency. Matching knurling wheel: compatible with a full range of flowershaped knurling wheels. Machine type: automatic machine, can be used with an accompanying machine; center height is adjustable to fit different setups. Applications and use scenarios In fabric finishing lines where twill patterns are produced, the extrusion type enables precise lateral adjustment during processing for consistent pattern results. When upgrading or integrating with an accompanying machine in an existing production line, the center height can be adjusted to match equipment, ensuring stable operation and reliable knurling. In usage environments, the special hardening extends service life, reducing downtime and replacement frequency.
