Abstract: A high proportion of fly lint and dust is intercepted inside a loom before settling, by a suction device (17, 18) positioned inside the loom below the rear shed and the heald frames so that air from a blower head (3) movably mounted (at 4) above the loom must pass through the rear shed and between the heald frames. The suction device has a plurality of suction boxes (18) pivotally interlinked with each other to form a suction channel chain (17) which is flexible so that the position of the suction channel chain (17) can be adapted to the space available inside the loom for an effective interception of fly lint and dust. One section of the suction channel chain extends approximately horizontally parallel to and below the rear shed, while another suction channel chain section extends approximately vertically and approximately parallel to the heald frames.
