Next, the operation of the present invention will be described.

First, in the composite spinneret attached to the spinneret base shown in FIGS. 1 to 3, a split spinneret having a spinneret inner frame made of a curable member is attached to a spinneret base of a clay kneading machine. Each of them is attached via a mounting bolt, and several thin plates for adjusting the thickness are provided on the joint surface of the split type base.

In some cases, an adjusting plate that defines the longitudinal width of the tile base material is attached to the joint surface of the split type die.

Therefore, the tile base material is continuously fed out through the mouthpiece of the inner frame of the split type mouthpiece made of a curable member .

When the mouthpiece of the inner frame of the mouthpiece is abraded through the continuous feeding of the roof tile base material, the degree of wear is adjusted by the removing method of the adjusting plate to obtain a regular size (so-called regularity). (Thickness) roof tile base should be paid out.

In the above-mentioned method of removing the thin plate for adjustment, normally, when the degree of wear of the mouthpiece of the inner frame of the mouthpiece is large,
Remove the split-type base from the base, remove the unnecessary inner- frame of the base that remains on the inner surface of each base by crushing, cutting, etc. And

Thereafter, a split type outer frame of the die is mounted on the molding table.
For example, they are united with each other via a tightening bolt (not shown), and are placed on the forming table, for example, with the kneading material receiving side facing upward.

An inner surface having a size slightly larger than the outer size of the tile base material having the concave-convex locking portion is formed on the united outer frame of the divided type mounted on the molding table.

Thereafter, a model for molding a tile base material having a drawing gradient is inserted into the inner surface and fixedly placed between the molding table and the outer frame of the die.

As a result, a space is formed between the inner surface and the outer peripheral surface of the model, and a hardenable portion of concrete, plastic, aluminum or the like is placed in this space.
A material (hereinafter, simply referred to as a curable member ) is filled.

After that, when the model is removed at the time when the curable member is cured, an inner die frame having a mouthpiece portion for roof tile base forming is formed there.

A split-type die having an inner die frame made of a curable member constructed in this manner is
Remove the tightening bolt (not shown) to divide the split type base with the inner frame of the base in this combined state.
Install the base in the same manner and procedure as above.

The method of use and other operations thereafter are the same as those described above, and unless the metal material is damaged, the curable part is used.
It can be used for reuse or production of multi-variety tile base material by re-repairing the inner frame of the die formed of the material or changing the shape of the model, or it is useful for facilitating the die control and reducing the cost. .

Next, in the composite die of the die which also serves as the die base shown in FIGS. 4 to 6, the die which also serves as the die base provided with the die body made of a curable member is used as a box for a dough forming machine. Is attached to the brim piece through a mounting bolt, and the protective plate provided on the mouthpiece which also serves as the mouthpiece base is attached to the side of the box.

Therefore, it is protected by the protective plate and cured.
The tile base material is continuously drawn out through the mouthpiece portion of the mouthpiece main body made of a flexible member .

Note that, unlike the above-mentioned example, since this example is an integral type, in principle, adjustment of the mouthpiece portion by the adjusting plate is impossible. However, the width adjustment in the longitudinal direction is configured to be adjustable via the adjustment plate as in the above.

If the mouth of the mouthpiece is worn due to continuous molding of the tile base material, the mouthpiece that also serves as the mouthpiece stand is removed from the collar piece of the box, and then the protective plate is removed, and then remains in the mouthpiece opening of the mouthpiece stand. The unnecessary base body is removed by crushing, cutting, etc., and as a general rule, the base is provided with the base opening provided with the concave-convex locking portion made of the original metal material.

After that, the dope is placed on the forming table so that the dope receiving side of the die is facing up.

A model for tile base molding having a withdrawal gradient is inserted into a mouthpiece opening having a concave-convex locking portion of a mouthpiece stand placed on this forming stand, and the model between the forming stand and the mouthpiece opening is inserted. Place it fixedly on.

As a result, a space is formed between the opening of the die and the outer peripheral surface of the model, and this space is filled with the curable member .

After that, when the model is removed at the time when the curable member is cured, a die body having a die mouth portion for roof tile base forming is formed here. Attach the protective plate that protects through the mounting bolts.

The thus-configured mouthpiece which also serves as the mouthpiece base is attached to the collar piece of the sack box by substantially the same operation and procedure as described above.

The subsequent method of use or other work is the same as that described above, and unless the metal material is damaged, the curability is set.
It is useful for reusing the inner frame of the die formed of the members , changing the shape of the model, or the like, for the effect of being able to reuse or manufacturing a multi-variety tile base material, or facilitating the die management and reducing the cost.
