Suction channel for fiber bundling device for stretching tool in textile machine, comprises tubular base structure with narrow suction slit(s) providing good compressing effect with low energy consumption

摘要

In a suction channel (15) for a fiber bundling device (1), located downstream of a stretching tool (3) of a textile machine, comprising a tubular base structure (23) with an external sliding surface (17) for an air-permeable conveyor belt (12) and suction slit(s) (18) running in the peripheral direction of the base structure, the width of the suction slit is less than 1.3 mm. An independent claim is included for a fiber bundling device with a suction channel as above and clamping roller (19) forming a clamping line (13), where the spacing between the end of the suction slit and the clamping line is less than 7 (preferably 4-6) mm.
