improvements to machines for washing in continuous and wide fabrics knitted on machines and ordinary and improved

摘要

An apparatus for the continuous immersion washing of uninterrupted pieces of fabrics, particularly of knitted fabrics, progresses the length of fabric through a series of washing stations including immersion washing tanks and progressing mechanisms including fabric widening rollers. At least one immersion washing tank has an intermittently driven rotary member partially immersed therein and having circumferentially distributed first projections which form a platform with second projections distributed along endless sprocket chams which drive the rotary member. Portions of the fabric are fed and loosely folded in relaxed tensionless condition onto the platform. A pair of axially-aligned, independently-driven and controlled half rollers exert transverse pulls on the fabric to counteract and correct misalignments detected and signalled by sensor means located downstream of the immersion washing tank.
