Abstract
To improve performance and to overcome dangerous problems of overheating in projectile looms, the loom brake has a cooler for dissipating the heat of braking and for reducing local temperature peaks. A coolant is guided in a flow into the vicinity of the braking surfaces. Appropriate cooling facilities can have air nozzles aimed at the braking surface, a liquid circuit supplying coolant to ducts within the brake shoes or tubes in heat-conductive contact with the brake shoes or heat pipes.
