摘要：This invention utilizes a conventional meat skinning machine having a frame, anelongated 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 rollclosely adjacent the blade. The motor is a braking motor which has a normallyinoperative braking means adapted to stop the motor substantially instantaneouslywhen 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 beclosed when the blade and gripping roll are electrically connected by any
electroconducting means, such as an operator's glove made of electroconductingmaterial, that simultaneously comes into electrical contact with the blade and thegripping roll. The closing of the safety circuit causes the braking means to be actuatedsubstantially instantaneously to stop the braking motor and to stop substantiallyinstantaneously any further rotation of the gripping roll. The method of the inventionincludes connecting the blade, the gripping roll and the braking motor in a normallyopen safety circuit. The safety circuit is closed by electrically connecting the blade and
the gripping roll through placing a glove on the hand of the machie operator comprisedof electroconducting material. The rotation of the gripping roll is substantially
instantaneously stopped by closing the safety circuit through simultaneously contactingthe blade and the gripping roll with the operator's glove.
