縮碼上針組采數(shù)位式速度控制方式傳動，可達準確性之線性運行，不論高低速時，皆可得到最佳縮碼效果。
布胚進布壓輪采用專利設計氣動式上下控制，方便操作又可調(diào)節(jié)壓布時之受壓壓力，使布胚縮碼量更精確平穩(wěn)。
入布展邊器配合防卷牙板，結合下平皮帶組，使布胚上針時達到最佳展邊上針功率，降低布邊損耗率。
機械縮拉碼設計范圍從-20%~+50%?？蛇m應各種織物之超喂率。
Overfeed pinning on device is controlled by a digital speedregulator,  to achieveprope r linear movement with great accuracy at any speed it is operating.  The PATENTED selvedge
press wheel adopted the pneumatic up down control and adjustable pressure arrangements.will stabilize increase overfeed performance.  Fabric selvedge expanding wheel and anti-curling scroll board,  working in collaboration with the under belt set.  ensures optimum pinning on effect with minimized fabric selvedge IOSS.   Overfeed ratio:   -20%-+50%,to match all the ove rfeed requirements.
