MACHINE FOR WRAPPING WARP OR OTHER YARNS - Patent No. 2274201 - 1976 translation

Sep 21, 2026

Invention disclosed a machine for wrapping warp yarns or other yarns used in textile, tapes, and woven or knitted fabric production. The aim is to form, before weaving on traditional equipment, wrapped yarns around elastic or non-elastic yarns, including loops and knots. The mechanism combines alternating angular and translational motions between needle supports and comb guides, passing warp yarns through holes and synchronizing yarn displacement to produce the wrapped output.

FAQs

What problem does the machine invention address?

It addresses producing distinctive wrapped yarns formed prior to weaving using a wrapping machine for warp yarns or other yarns.

How does the machine wrap the yarns?

It uses synchronized alternating angular and translational motions between needles and comb guides so warp yarns pass through shaped holes and form loops and knots around the yarn to be wrapped.

What major parts are described in the machine?

The description includes an unwinding device with bobbins, a feeding system with rolls for driving and tension, knitting and knotting points, a drawing system of rolls, and a receiving/winding system for wrapped yarn.
