The block-shaped food 18 placed on the upper surface of the container 20 is carried into the cylinder-making mechanism 20. In addition, the carry-in pitch of each food 18 into the cylinder-making mechanism 20 depends on the cross-seal
Due to the need to be absolutely synchronous with the zero rotation cycle, the chain wheel 14 receives power from the prime mover in the pedestal frame.

In the direction of loading of the food 18, a conveyor belt conveyor mechanism 3 is provided behind the loading conveyor mechanism 13.
0 is mounted and installed on two shelf bars 21 protruding from the vertical wall surface 12 of the wall frame, and the conveyor belt conveyor mechanism inherits the transportation of the food 18 from the carry-in conveyor mechanism 13.

A belt-like film 33 supported on a storage shaft 31 and pulled out by a feeding roll 32 is shaped into a groove by passing between two raised walls of the cylinder mechanism 20 at a constant interval. Therefore, the food 18 is substantially transferred to the grooved film and then transferred to the transfer belt conveyor mechanism 30.

As shown in FIG. 2, the conveyor belt conveyor mechanism 30 supports two end pulleys 22 and 23 on a reinforcing frame 24, and stretches an endless belt 25 around these two end pulleys. An input gear 27 is fixed to the operating shaft 26 of the one end pulley 22. A part of the reinforcing frame includes a tank structure 35 communicating with the suction pipe 34. When a number of holes 36 of the belt pass over the slits 37 on the tank structure 35, vacuum suction is applied to each hole 36. When a force is applied, the belt-like film is attracted to the holes 36 and pulled by the rotational force of the belt 25.

As shown in FIG. 2, the conveyor belt conveyor mechanism 30 is set on the shelf 21 as described above. In this case, the U-shaped bracket 3 fixed to the tip of the shelf
