Abstract
A yarn heating apparatus which is adapted for use in a yarn false twisting machine. The heating apparatus includes an elongate heating surface, and a plurality of yarn guide members mounted in a longitudinally spaced-apart arrangement along the length of the heating surface, for guiding an advancing yarn therealong in a laterally zigzagged path of travel which is adjacent but spaced from the heating surface.
Claims17
An apparatus for heating an advancing yarn, comprising:
- an elongate heating surface,
- means for heating the heating surface, and
- yarn guide means comprising a plurality of guide members mounted in a longitudinally spaced apart and interdigitally disposed arrangement along the length of said heating surface for engaging opposite sides of an advancing yarn and guiding the same along the heating surface in a laterally zigzagged path of travel which is adjacent but spaced form said heating surface along the entire length thereof.
An apparatus for heating an advancing yarn, comprising:
- a body member having an elongate channel therein,
- a heating surface positioned in said channel and extending along the length thereof,
- means for heating said heating surface, and
- yarn guide means comprising a plurality of guide members, and means mounting said guide members in a longitudinally spaced apart and interdigitally disposed arrangement in said channel for engaging opposite sides of an advancing yarn and guiding the same along the heating surface in a laterally zigzagged path of travel which is adjacent but spaced from said heating surface.
A yarn false twist crimping machine for processing synthetic yarn and comprising
- yarn heating means, yarn cooling means, yarn false twisting means, and means for advancing a yarn serially through said yarn heating means, said yarn cooling means, and said yarn false switching means and for winding the processed yarn into a package,
- said yarn heating means comprising an elongate heating surface, means for heating the heating surface, and yarn guide means comprising a plurality of guide members mounted in a longitudinally spaced apart and interdigitally disposed arrangement along the length of said heating surface for engaging opposite sides of an advancing yarn and guiding the same along the heating surface in a laterally zigzagged path of travel which is adjacent but spaced from said heating surface along the entire length thereof.
