Abstract
Abstract A textile machine, which comprises a stand-off creel, first, second and third feed means, first and second heaters, cooling zone, false twist device and take-up means, has the second and third feed means, false twist device, second heater and take-up means mounted on a common frame with the second heater disposed vertically behind the take-up means and the third feed means located forwardly of the second heater, and has guide means operable to guide a yarn from the outlet end of the second heater through 90° to the third feed means. This enables the second heater to be mounted lower in the frame than with previous machines and enables the false twist device, second feed means, cooling zone and first heater to be positioned nearer to the operator for operation, maintenance or cleaning.
