Abstract
A mechanism for the production of wrapped yarn which consists of a bundle of spun fibers wrapped around a binding thread. A hollow spindle 5 is supported between a pair of delivery rolls 1, 2 and a pair of draw-off rolls 3, 4. A rotating binding thread bobbin 7 is arranged coaxially with the hollow spindle 5 and is enclosed by a housing 8. An air flow which can be generated in the housing and/or introduced into the housing causes the pressure within the housing to be built up so as to prevent fibers and the like from entering an exit hole carried in a cover 80 provided on the housing.
