Abstract
A filter box contains within a rotatably mounted filter, structured as a drum, a fiber preseparator cooperating with such filter. The fiber preseparator has a ventilator at its inlet and operatively flow communicates with a fiber separator. This fiber separator contains a movable plunger or equivalent structure, by means of which the separated fibers are compacted and ejected into a collecting container. The air flowing through the filter effluxes through an opening in the filter box into the machine room or area containing the textile machines with which the filter box is used. The air responsible for transport of the fibers from the preseparator into the fiber separator, following separation from the fibers, is returned back to the suction side of the ventilator and again into the preseparator. A suction tube cooperates with the inner side or wall of the rotating filter drum. This suction tube likewise flow communicates with the suction side of the ventilator by means of a dust separator. Connected with the dust separator is a dust collecting container. The filter box is particularly suitable for connection with textile machines of the type which only permit slight pressure fluct…
