Abstract
In an arrangement for texturing threads used in producing yarn, the threads are preheated by passing through channels of a contact heater before passing through the known yarn texturing, e.g. false twisting units. To increase thread and yarn production with a particular contact heater, two threads are passed through a respective heating channel in the heater, rather than one thread. To accomplish this, one thread has a right hand, regular or Z-twist or turn and the other has a left hand, reverse or S-twist or turn, and their crimp causes them to avoid each other at opposite sides of the channel, and not to undesirably contact. A respective texturing unit is supplied for each of the threads that has been heated.
