<p>A machine for acting on continuously running textile yarn, such as a texturising machine, has a doffor system including a plurality of doffer tubes each having apertures, at spaced intervals therealong, each normally closed in use by a sleeve. Each tube has an internal diameter of from 20-10mm, and the area of each aperture is at least 30% of the internal cross-sectional area of the tube. The result is a system which gives mere yarn tension and faster threading-up times with reduced material costs, reduced-size exhausted and lower power requirements.</p> |
