Abstract

Abstract A product encasing machine comprising an adjustable hopper for product casings, the hopper being positioned above a clamp means comprising front and rear V-shaped seats. The front and rear seats are adapted to receive one casing at a time from the hopper when in their open position. The front and rear seats are movable from the open position to a closed position so as to grasp the casing therebetween and position the same to permit a stuffer tube to be inserted therein. The stuffer tube slidably extends through and is in communication with a meat pump to permit the stuffer tube to inject the meat product into the casing. The clamp seats return to their open position after the stuffer tube has been inserted into the casing. The machine includes a linking assembly which links the product into uniform links. A looping assembly automatically deposits the links in uniform loops on a take-away conveyor. A cam follower rod is slidably mounted below the stuffer tube and has a casing follower mounted thereon which moves along the stuffer tube and engages one end of the casing to compress the casing before it is rotated and to maintain uniform pressure on the casing as the meat product is encased in the casing. A counterbalanced arm member extends through the front clamp seat and prevents the closing movement thereof to prevent recycling of the machine unless a casing is positioned thereon. Means is provided to prevent damage to the fragile casings as they are being handled by the machine. Means is also provided for precisely controlling the operation of the stuffer tube, cam follower rod and casing clamp so that the machine properly cycles to automatically produce a uniformly encased product.
