Next, the manufacturing process of the innermost skin will be described in order. First, when the mold 4 that is circulated and driven by the chain drive device 3 is positioned at the upper position and the male mold 4A is rotated upward, it is not shown. The middle dough is fed from the dough feeding device into the molding recess 11 of the female die 4B. The female die 4B supplied with the dough is sequentially conveyed together with the male die 4A to the rear side (right side in FIG. 1) of the frame 2 by the chain driving device 3. At this time, the engaging portion 6a provided at the rear end of the support lever 6 to which the male mold 4A is attached engages with a guide member (not shown) and rotates as it is conveyed. Therefore, the male mold 4A is driven so as to be placed on the female mold 4B. Eventually, as shown in FIG. 5, the male mold 4A and the female mold 4B are engaged, and the fabric put in the molding recess 11 is It will be filled in the molding space 18 formed between the molding convex parts 8. At this time, the male mold 4A and the female mold 4B are locked so as not to be opened by a lock mechanism (not shown).
[0022]
Then, the mold 4 is further conveyed rearward in this state, and eventually passes over a heater (not shown) provided on the rear end side (right side in FIG. 1) of the frame 2 and is heated by this heater. Thus, the dough accommodated and held in the molding space 18 is fired. At this time, the generated steam escapes from the molding space 18 through the notch groove 13 provided in the peripheral edge 12 of the female die 4B.

Then, the male mold 4A having the innermost cover on the molding convex portion 8 is conveyed in a vertical state, and at this time, the extrusion device 17 located on the rear side (left side in FIG. 2) of the male mold 4A. When the pressing plate 17a is moved in the lateral direction in synchronization with the conveyance of the mold 4 and driven in a direction in contact with and away from the male mold 4A, a plurality of extrusions projecting to the rear side of the male mold 4A The rear end of the pin 10 is simultaneously pushed forward (rightward in FIG. 2). As a result, the tip of the push pin 10 acts to push up the end face of the innermost skin that covers the molding convex portion 8 and to push out the innermost skin from the molding convex portion 8.
[0026]
The innermost core pushed out from the molding convex part 8 falls on the transport conveyor 7 located below, and is taken out of the apparatus by the transport conveyor 7.
[0027]
As described above, molding and removal of the innermost skin are completed.
[0028]
The pressing plate 17a of the extruding device 17 moves backward to the conveyance upstream side (right side in FIG. 1) of the mold 4 to prepare for the next operation after the extruding pin 10 is pushed out. In addition, each push pin 10 that has lost its pressing force due to the pressing plate 17a retreating is in an original state in which its tip is flush with the flange portion 9 due to the biasing force of the spring 16 built in the cylindrical portion 15. Return to.
[0029]
On the other hand, the mold 4 from which the innermost skin has been taken out is folded upward at the front end side (left side in FIG. 1) of the frame and conveyed in the original direction, whereby the dough is supplied again at the predetermined position. Is done. In this way, the above operation is repeated.
[0030]
