Guide Bar Shogging and Pattern Mechanisms
topic
Guide bar shogging mechanisms move each guide bar laterally by defined numbers of needle spaces on each course according to programmed pattern sequences, with electronic pattern mechanisms using servo-driven eccentric cams or direct linear actuators controlling shogging displacement for each guide bar independently at speeds up to 4000 courses per minute, with shogging pattern defining the underlap and overlap structure that creates the warp knit stitch and fabric pattern.
Role
Determines the fabric stitch structure and pattern characteristics of warp knitted fabrics through the programmed guide bar lateral displacement sequence, with guide bar shogging pattern being the primary design variable that controls fabric extensibility, transparency, and decorative effect by defining how each guide bar yarn wraps around needles and lays underlap between stitch columns across the fabric repeat.
