(57) A yarn texturing machine (10) having an air jet (24) for combining and texturing
at least two yarns (15, 16) to form a single textured yarn (30), comprises respective
yarn feed and drawing devices (17, 18, 19, 20) for each yarn (15, 16). To give good
control of the yarns (15, 16) in the low tension region upstream of the jet (24) the
drawing devices (19, 20) are positioned relative to the jet (24) and each other so
that the yarns (15, 16) travelling to the jet (24) travel along straight, spaced yarn
paths which converge at the jet (24) at an angle of between 70o and 50o, and lie in a plane inclined at between 60o and 90o to the axis of the jet (24). After the jet (24) the textured yarn (30) is passed
upwardly then downwardly over a setting heater (33) located above the jet (24) and
then to wind-up means (36) disposed beneath the jet (24).
