という問題がある。(2) Prior Art Conventionally, in order to create a master model for a mold, the circumference of a tire 1 is divided into, for example, 12 equal parts, as shown in Figure 1a, and then piece 2 (tire 1/24 of
As shown in Figure 1, a plaster model 3 with a profile IL/ corresponding to the tread part of piece 2 and without any patterns (grooves, etc.) is made for the piece (piece), as shown in Figure 1. While observing the tread pattern rfJ (not shown) as shown in FIG. The master model 6 is completed by digging pattern grooves etc. 5 using the . In this way, in the conventional method, there are five steps: creating a plaster model, inscribing, and engraving.
In particular, even though there are 144 pieces of tire 1, the tread pattern is complicated in most cases, so it takes a long time even for an experienced person, and it takes a long time to finish the whole process. However, there is a problem that the construction period is too long and productivity is poor.

に重ね合わせ一体化することを特徴とするものである。(4) Structure of the Invention The present invention divides a pattern diagram of an article having a pattern into multiple parts in a slit shape, and each division sequentially creates a profile diagram for each part. Figure 2 According to the above pattern diagram, each section has a pattern having a thickness equal to the width of the section, and each section has the profile of the section cut to create a large number of patterns with profiles, and these patterns with profiles are sequentially processed. It is characterized by being overlaid and integrated.

- Each profile diagram 11 is created sequentially for Sn, while each section of the pattern diagram 10 is divided into portions s1. s2. s3+... A paper pattern 12 having a thickness equal to the width of Sn is required. The material of the paper pattern is, for example, paper 1 gypsum, aluminum, 4, etc., and gypsum is particularly preferred from the viewpoint of finishing work and repair work. From each profile diagram and pattern diagram, each pattern has a section 84,
S2. ...Sn profile/L"& a known profile cutting machine (for example, wire cutter) is cut using an NC electric discharge machine, and a large number of profiled patterns 15 are cut.
Create. Finally, the profiled paper patterns 16 are successively stacked and integrated with plaster adhesive to complete the master model piece (for example, 724 heath of a tire) 14, and when these 24 pieces are combined, the master model is completed.
