Due to the flow of the meat based on the pushing forces F 1 and F 2 of the slopes 3a and 3b of the forming roller 3, the shape finally merges at the top of the ridge m, thereby causing molding defects at the top of the ridge m. A certain type of top roll C tends to occur, and this top roll C damages the belt and adversely affects the belt life. Therefore, in order to remove this top roll C, it was necessary to turn the peak m.

In the present invention, in the preforming process using the preforming roller (Fig. 1C), instead of simply forming a V-groove with a substantially trapezoidal cross section, the bottom surface of the V-groove is formed into a multi-striped V-groove that is the shape of the final product. It is characterized by being preformed into a wavy shape.
以下、この発明のより具体的な実施例を図面を

備えている。 FIG. 3 is a diagram showing the first embodiment of the method of the present invention, and the steps A, B, and D in the same figure are the same as those in FIG. 1.
It is the same as D, only the preforming process of FIG. 3C is different. In this embodiment, as shown in FIG. 3C, the preforming roller 12 that controls preforming is different from the one in FIG. It has a wave-shaped preformed surface 12a.

うにＶ溝部S2の底面を断面波形状に成形する。 Then, by pressing the preforming surface 12a of the preforming roller 12 against the outer peripheral end surface of the material Q that has been slotted into a substantially V-shape in the previous step B and rotating it synchronously, the slotted groove S1 is formed into a substantially trapezoidal cross section. The V-groove S 2 is formed by expanding the V-groove S 2 , and the bottom surface of the V-groove S 2 is shaped into a wave-shaped cross section as shown in FIGS. 4A to 4C.

する。 At this time, the wavy shaped surface W formed on the material Q side
The relationship between the peaks and valleys of is the multi-row V of the final product shape.
This corresponds to the relationship between the peaks and valleys of the groove S 3 (FIG. 3D).

As shown in the figure, since the wave-shaped preformed surface 12a is pressed against the V-shaped slotted groove S1 , when looking at the growth process of the mountain part m1 on the material Q side, mainly one slope part 12b and the flow of the material toward the deepest part d of the slotted groove S forms the mountain part m1 , and as in the conventional case, the mutually countervailing pushing force F2 (Fig. 2) C) does not have a large effect and no toprol is generated at all.

である。 The present embodiment is basically the same as the first embodiment, but as shown in Fig. 5E and Fig. 6A, the deepest part d of the slotted groove S1 is raised to form a peak m3.
Since it is necessary to form the ridges m on both sides,
Regarding m, as in the first embodiment, topprol c
Although it is possible to completely prevent the occurrence of
For m 3 , a slight top roll occurs for the same reason as shown in Figure 2. For this reason, a step (FIG. 5C) of widening the split groove S1 formed by the auxiliary roller 4 is added before the preforming step (FIG. 5D). Note that D and E in FIG. 5 are steps corresponding to C and D in FIG. 3, respectively.
