Yarn heater and yarn processing machine

摘要

In a yarn heater (1) (specifically a contact heater) with heated wall(s) (5) located on yarn guide(s) (3), the device (9) for heating the walls consists of heating wire coils (10) along the yarn guide, which are divided into coil sections (11, 12, 13) of specific winding densities such that the temperature profile is at least partly variable during the operation of the heater. An independent claim is included for a yarn processing machine incorporating the yarn heater.
