ABSTRACT:
A belt guard for clutch motors for industrial sewing machines comprises a cover made of two cover halves which can be clapped together. This cover extensively covers a V-belt pulley part of which accommodates a V-belt. In order to achieve an effective ingoing belt safety device which can be adapted to suit a variety of V-belt pulley diameters without exceeding the permissible maximum distances to the ingoing V-belt section on the one hand and to the V-belt pulley on the other the ingoing belt safety device comprises a safety pin extending into the wedge-shaped area between the ingoing V-belt section and the V-belt pulley. This pin can be attached to a safety slide bar fixed to a cover half in an adjustable manner, or to a disc serving as a mount for the cover halves.
