Abstract
A thread brake for a textile machine, in particular a shuttleless loom, in which weft thread lengths are withdrawn from a store disposed outside the shed, wherein interruption of weft thread take-off is carried out by displacement of a take-off roller 6 rotating at constant peripheral speed from an operative position to an end position remote from the thread 1. The device comprises at least for one brake shoe a movable holder 21 which is movable between two end positions in the direction of the gap towards a holder 21' of the other brake shoe and at least indirectly connected to the loom shaft 8 in driving relationship. The displacement of one or each holder occurs against the force of a spring 23 or 23' which in the unloaded state corresponds to a distance between the two brake shoes corresponding to thread thickness. The thread brake according to the invention has, due to displacement of the holder(s) and hence the brake shoes, in operation an automatic cleaning action on account of which the brake shoes are automatically cleaned of deposited fluff.
