ABSTRACT:
Apparatus for feeding and tensioning threads in a textile machine including corresponding weaving members supplied with the threads. For each thread, a calander is provided with first and second superimposed wheels between which the thread, coming from a corresponding store located upstream of the apparatus, is made to pass. The wheels are mounted on corresponding parallel, horizontal shafts. A body for supporting the wheels is rotatively mounted on a corresponding body shaft having axis parallel to one of the wheels. The body itself is supported by a fixed bearing structure. A thread-holder arm of flexible and elastic material is provided with one end fixed to the body and the other end of the arm is provided with a thread-guiding ring through which the thread, coming from the calander (H), is made to pass. The arm is located above the weaving device of the machine in order to drive the body into rotation about the corresponding body shaft when the pull exerted on the thread by the weaving device is greater than a predetermined value.
