When the rod of the third air cylinder 92 reciprocates forward and retracts reciprocally, the rotating disk member 8 rotates clockwise and counterclockwise through the swing member as described above.

7 to 12, the operation of the apparatus 2 will be described. According to FIG. 7, the conveyor 52 transports a spherical dough 58 for Chinese bread in the area immediately below the device 2. When the dough 58 has reached this area, the sensor 70 senses the presence of the dough and sends a signal to the motor 54 of the conveyor and the first air cylinder 68 of the placement device 56.

In response to the signal from the sensor 70, the conveyor 52 is stopped to align the center of the spherical dough 58 with the center of the opening 48 as shown in FIG. In this movement, the forming member is located at the outermost position as shown in FIG. At the same time, the rod 66 of the first air cylinder 68 advances in response to a signal from the sensor 70, so that the innermost end of the thin blade portion 24 is shown in FIG. The plate 64 pushes the spherical dough upwards towards the forming member 4 of the device 2 until it is in contact with the upper part of 58). When the rod 74 stops moving forward, the third air cylinder 92 operates to rotate the rotating disk member 8 so that the forming member 4 moves inward.

As described above, the forming member 4 cuts the upper portion of the spherical dough 58, and the forming member is the housing (center) of the circular arrangement of the forming member 4 when its inner end portion is in its innermost position. Since it is aligned so as to be located laterally away from the center of 12), when the forming member is moved inwardly, the upper portion of the dough is twisted clockwise when coming from above about its vertical axis as shown by the arrow of FIG. As shown in FIG. 1I, most of the inclined blades 26 of the shape member 4 cut the upper portion of the dough material 58 when it is located at its innermost position. As shown in the figure, it narrows down to its minimum size. After that, the rod 66 of the first air cylinder 68 is operated so that the compartment 64 and the spherical dough 58 thereon are downward, and the third air cylinder 92 is operated to form the forming member 4. The rotating disk member 8 is rotated to move the outward direction. When the forming member 4 returns to its outermost position as shown in FIG. 5, the second air cylinder 72 operates to advance the rod 74 such that the shaft 50 has its bottom end 12th. Advance through the axial hole 36 until it engages the upper portion of the spherical dough as shown in the figure.

After that, the motor 54 operates to axially rotate the shaft 50 clockwise as shown by the arrow in FIG. After that, the upper part of the spherical dough 48 is seen. The result is a final dough product that is more twisted and thus has an upper portion that forms twisted folds.

After that, the second air cylinder 72 is operated to remove the rod 74, and the conveyor 52 is operated to discharge the final dough product and the next dough into the area immediately below the opening 48 of the forming member 4. To supply. The arrangement in which the device 2 operates automatically is not limited to that described above.

Instead of the arranging device 56 for raising and lowering the spherical dough placed on the belt of the conveyor, the device 2 may be raised or lowered by an arm extending from the device mounted on the frame of the conveyor. The lifting and lowering device may have a conventional structure including an air cylinder system. Similar to the operation of the arrangement described above, the ascending and descending devices operate synchronously with the supply of spherical dough. The shaft 50 may have a pin point at its lowest end instead of the wedge portion. The lowermost end of the shaft 50 may have any shape as long as it has a shape sufficient to cut the surface of the spherical dough.

In manual operation, the device 2 is supported by the operator and placed on top of the spherical dough material 58. By using the handle attached to the rotating disk member 8, the operator can rotate the member to form the upper portion of the spherical dough into wrinkles. After that, the device 2 is lifted to remove the formed spherical dough.

Preferably, the operator may insert the shaft into the upper portion of the formed dough and rotate about that axis to more twist the upper portion of the spherical dough. After that, the dough is discharged and transferred to the steam room for steaming.

In the present invention, the plate is changeable in shape by changing the level at which the columnar mass is raised and the rotation angle of the rotating disk member. If the columnar agglomerate is made of a high elastic material, the agglomerate will rise high and the rotating disc member may be rotatable to the maximum so that the molding member can be cut deep into its surface.

In contrast, if it is made of a low elastic material, since the plate can be easily formed, the rotating disk member will rotate less and the mass will rise less than if the mass is made of high elastic material.

Since the molding member in the present invention comprises a thin and long blade, it is cut into the top surface of the cylindrical mass. The creases formed on top of the mass are deep enough and eventually they remain on the mass even after the mass is steamed. In addition, since the forming member is arranged such that the inner ends of each member are spaced apart from each other so that the member is positioned next to the center of the housing when the member is in its innermost position, the top of the cylindrical mass is Twist when moving inward. Thus, a cylindrical mass having a pleated twist on top of it is produced. Therefore, according to the present invention, Chinese bread which appears to have manually formed wrinkles can be produced after the formed mass has been steamed.
