Preceding surface 1D direction tilts.
Fig. 3 shows Foamex blade base 2, the Foamex blade base 2 be made up of foamed synthetic resin and
With the overall shape identical shape with blade 1.Although material is substantially unrestricted, the polyphenyl that for example foams has been used
Vinyl.Matrix 2 can cut foamed board by using cutting machine or be manufactured by using mould molding.Work is molded in mould
It is excellent in terms of making efficiency.
Being drawn on the preceding surface of Foamex blade base 2 has the parting line with horizontal direction along the longitudinal direction, i.e. vertical
To parting line 2A and multiple horizontal parting line 2B, and Foamex blade base 2 is cut into blade as shown in Figure 4 point
Part 3,3 is cut, so as to form cut portion 4 in corresponding cutting part office.
For example, the length of blade 1 is 1m, thus it is illustrated that and forms 8 partition members, in 8 partition member
The length of each partition member be about 25cm.
As shown in Figure 4, adhesive is sprayed on the cutting in a longitudinal direction of the partition member 3,3 at root of blade
On part 4,4, wherein, cut portion 4,4 can combine to each other along left right, so as to form adhesive phase 5,5.In Fig. 5
