Abstract
A heating device for heating at least one advancing yarn in a texturing machine, wherein the body of the heating device defines an elongate heating channel. The heating channel accommodates an exchangeable support which mounts a plurality of yarn guides which are arranged inside the heating channel for forming a plurality of adjacent yarn guide tracks for guiding a plurality of yarns in such a manner that the yarns advance in a yarn advancing plane extending at a predetermined distance from the bottom wall of the heating channel.
Claims12
A device for heating an advancing yarn comprising
- an elongate heater body having a channel therein which extends in a longitudinal direction along the length thereof, with the channel defining opposite side walls and a bottom wall,
- a heater for heating the side and bottom walls to a surface temperature approximately to or above the melt point of the yarn to be processed,
- a yarn guide support positioned in the channel and mounting a plurality of yarn guides so as to form a plurality of side-by-side yarn guide tracks which extend longitudinally along the channel at a distance from each of the side and bottom walls and for guiding a plurality of yarns in such a manner that the yarns are guided in a predetermined spaced relationship to the bottom wall and in a zigzagged manner.
