Yarn laying - has deflection point to sever yarn between sleeve and take-off without a blade

摘要

To lay a yarn at a constant speed on to a bobbin, clamped to a rotating spindle, the yarn is deflected between the yarn take-off and the sleeve at a point behind the sleeve, as seen from the take-off point of the take-off appts. The deflection point lies between the tangents from the take-off point towards the plane where the yarn is caught at the sleeve. After the yarn has been caught, the deflection guide moves at least 90 deg. round an incoming and emerging yarn level for a twist on a generally symmetrical axis. ADVANTAGE - The technique requires no blade for the yarns moving at high speeds, working with thick yarn material, to sever it between the bobbin sleeve and the take-off.
