Abstract
A yarn heating apparatus for use in a yarn false twisting machine, which has an axial channel in which the yarn advances along a zigzagged path. To guide the yarn in the axial channel, yarn guides are provided, which are shaped as spaced apart protuberances on two metal strips. The metal strips are supported in contact with the side walls of the axial channel.
Claims20
An apparatus for heating an advancing yarn comprising
- an elongate heater body having a channel therein which extends in an axial direction along the length thereof, with the channel being of generally rectangular cross section and defining parallel opposite side walls and a central plane which is parallel to and equally spaced between said opposite side walls,
- means for heating the heater body, and
- yarn guide means disposed in the channel for guiding the advancing yarn axially along the channel in a laterally zigzagged path of travel, said yarn guide means comprising a pair of metal strips disposed in the channel so as to overlie and contact respective ones of the opposite side walls, with each of the metal strips including axially spaced apart protuberances which extend laterally into said channel and beyond said central plane, and with the protuberances of each of said metal strips being axially offset from the protuberances of the other of said metal strips.
An apparatus for heating an advancing yarn comprising
- an elongate heater body having a channel therein which extends in an axial direction along the length thereof, with the channel being of U-shaped cross sectional configuration and defining parallel opposite side walls and a central plane which is parallel to and equally spaced between said opposite side walls,
- means for heating the heater body, and
- yarn guide means disposed in the channel for guiding the advancing yarn axially along the channel in a laterally zigzagged path of travel, said yarn guide means comprising a metallic channel member disposed in said channel which has a U-shaped cross sectional configuration which closely conforms to that of said channel, with said metallic channel member comprising a base and opposite side strips, with said side strips disposed so as to overlie and contact respective ones of the opposite side walls of the channel, with each of the metal strips including axially spaced apart protuberances which extend laterally into said channel and beyond said central plane, and with the protuberances of each of said metal strips being axially offset from the protuberances of the other of said metal strips.
