Device on a spinning machine for producing a web of fiber flocks, for example made from cotton, chemical fiber

A spinning device for producing a web of cotton or chemical fibers, comprises a feed roller (6; 10) rotating slowly and a feed trough constituted by a plurality of individual troughs (7a to 7n; 14a-14n ) in rotation, and a separating roller rapidly rotating is arranged downstream of the feed roller (6; 10), the fibrous material is taken from an upstream feed chute and supplied to a downstream device for processing. To achieve a safe working device and allow accurate clamping of the fibrous material between the inlet trough and the feed roller, each feed trough (7a to 7n; 14a-L4M) comprises a bearing (26a-26n; 40a-40n) and the bearings (26a-26n; 40a-40n) are mounted on a common mounting member (25, 33) which extends over the width (b) of the machine .
