When descending, the tubular casing 6 is clamped and fixed in cooperation with the cradle 21. The protruding rod 19 is caused to reciprocate in the vertical direction by a cylinder device 24. Further, a roller 25 is pivotally supported at the tip of the protruding rod 19, so that the protruding rod 19 can smoothly come into contact with the tubular casing 6. In the figure, reference numerals 26 and 26 indicate guide rollers arranged on the supply side adjacent to the supply side chuck device 17.

Operation Next, the operation of the casing tensioning and feeding device 16 having the above configuration will be explained.

FIG. 1 shows a state in which preparations for filling the meat mass M have been completed, and in this state, the pusher 3 moves forward and the meat mass M in the meat stuffing hopper 2 is pushed out from the filling nozzle 4 and filled into the casing 6. be done. At this time, the casing tensioning and feeding device 16 is not activated.

FIG. 2 shows the casing 6 released from the casing holding means 13 by the actuation of the first cutting and binding device 14 after the casing 6 has been filled with meat M.
The opening end 6a of the opening end 6a is tightly bound and sealed with a stopper 30. This first cutting bondage device 1
