Abstract
A yarn-twisting apparatus has a frame on which is mounted at least one row of identical twisters. Fixed to this machine is a front wall panel extending along the row of twisters from the top of the cups thereof to the bottoms of these cups. Hinged on the upper edge of this front wall panel is one or a plurality of flaps which can move between a vertical position extending upwardly, or a lying-down position giving access to the tops of the twisters. Another such flap is hinged on a second front wall panel below and recessed from the front wall panel so as to be displaceable between an upper position shielding the arrangement and a lowered position giving access to the flyer disks of the twisters. These flaps and panels are all made of sound-deadening material and the various flaps may be subdivided so as to give access to individual twisters while the other flaps are left up so as to shield sound generated by the other twisters. Furthermore it is possible to provide two such rows of twisters on each machine with a vertical wall of sound-deadening material between the rows in order further to reduce the sound level generated by the machine. Wind shields are provided around each twist…
