<p>The invention refers to a brake for the main shaft of a loom in which in the transmission of the energy between the driving motor and the main shaft a disconnectable friction coupling controlled by supervisory members for the weaving process is interposed, which has a slidable pressure-piece which in one extreme position, with the weaving process in order, preserves frictional engagement between the main shaft and the driving motor and which in the other extreme position, in the case of disturbances in the weaving process, produces frictional engagement between the main shaft and a brake rigidly connected to the machine frame.</p> |
