This invention utilizes a conventional meat skinning machine having a frame, an elongated skinning blade, a rotatable gripping roll closely positioned adjacent the blade, an electrical motor operatively connected to the gripping roll and to a source of electrical power, and a danger zone defined by the area approximate to the gripping roll closely adjacent the blade. The motor is a braking motor which has a normally inoperative braking means adapted to stop the motor substantially instantaneously when becoming operative. A safety circuit is electrically connected to the braking motor, the blade and the gripping roll. The safety circuit is normally open and is adapted to be closed when the blade and gripping roll are electrically connected by any electroconducting means, such as an operator's glove made of electroconducting material, that simultaneously comes into electrical contact with the blade and the gripping roll. The closing of the safety circuit causes the braking means to be actuated substantially instantaneously to stop the braking motor and to stop substantially instantaneously any further rotation of the gripping roll. |
