Abstract: A mobile apparatus for pneumatically blowing and suctioning fiber fly or lint from textile machines by means of blowing and suctioning means respectively connected to a common fan by means of nozzles and suction members which sweep past the textile machine and across the floor and between which there is positioned a filter to extract the fiber fly or lint which is adapted to be impinged periodically by the air-blast stream in the opposite direction to clean said filter and convey the fiber fly deposited on said filter into a collection bin. In order to position the apparatus immediately adjacent to the working area, the apparatus is designed to move on a trackway provided on one side of the textile machine. The drive means is adapted to be automatically de-energized and reversed by limit switches provided on the apparatus. The fan is a radial blower fan.

Abstract: A mobile pneumatic apparatus for removing lint, dust, dirt and debris from textile machinery and the locus thereof, having a fan which on one side thereof has a pair of suction conduits generally opposed to one another and has on the other side a blower member, each of the suction conduits having filter means for removal of lint, dust, dirt and debris, the apparatus improved by the inclusion of a normally open suction gate downstream of the filter means in each of the suction conduits which upon actuation closes to prevent air from passing therethrough, and a normally open by-pass conduit in each of the suction conduits downstream of the filter means, the branch conduits by-passing the gate and being directed toward the filter means. Means are provided to close the suction gate by opening the branch conduit gate.
