Abstract

Apparatus and a threading method in a multi-unit spinning machine for synthetic fibers with an exposed front face of each winding unit, the apparatus comprising a soundproofing screen extending across at least one winding unit, means to move the screen along the front of the machine to offer soundproofing protection as the winding unit is placed into operation, and thread insertion means in the screen including an open-ended thread insertion slot extending longitudinally of the screen from its leading side edge. The threading method permits the simultaneous actuation of a winding unit and moving of the soundproofing screen into place as the unit is threaded with the help of a suction gun.
