Fabric guiding and centering unit which is used mainly for woven and warp knitted wider width fabrics. The unit works by means of two pcs of coated or tape-wounded cylinder that are not driven and allows the cradling movement with pneumatic piston located between the left and right frames. It does not require manual fabric width adjustment thanks to the optical sensor unit.
Both sensors read fabric edges and send this information to the control panel. Accordingly, pneumatic piston gives cradling movement to the two rollers and fabric gets centered by this movement.
