ABSTRACT:
The disclosure embraces noise abatement apparatus and a method of abating noise in a yarn texturing machine of the type that employs rotatable spindles driven by endless belts, heater means and yarn transport means, all of which are spaced along a frame between a gear housing and a motor housing; the apparatus includes sound insulating walls for enclosing the timing belt driven pulley located nearest the gear housing together with tunnels lined with sound absorbing material through which the endless belts of the machine pass from the gear housing over the frame of the machine; also, there are included means for isolating the vibrations of idler pulleys for the drive belts from the mounting rail as well as reducing sound propagation from the rotating idler pulleys; noise generated from within the gear housing of the machines is also suppressed.
