PURPOSE: To make a forming matter to be easily manufactured deformable later so that the possibilities of other use applications can be developed by forming at least, a single seam in order to have a semi-finished product made of a shrinkable plastic deformed. CONSTITUTION: A seam 2 which is provided so that a semi-finished product 1 can be deformed and supplied for a wide range of use applications, is formed in the semi-finished product 1 which is cylindrical and shrinkable. That is, the deformed semi-finished product 1 can be used as a branched member and in this case, two parallel extending small apertures 5 are formed from an initial large aperture 4 by stitching the seam 2 with a thread. In order to connect walls on the opposite sides of the semi-finished product 1, whatever kind of an accessory part such as a clamp, for example, is unnecessary. Further, the semi-finished product 1 can be split in the longitudinal direction and joined closely with a closing member 6 in the longitudinal direction. In addition, in order to expand the branched part beyond its existing state according to necessity, a cut 7 can be made in the seam 2 formed in the U-shape or the wedge shape. |
