METHOD FOR PRODUCTION WELD PLANISHING OF PLASTIC SHEET AND JOINT. |
摘要 |
The present invention discloses a planishing method for joined sheets made of a thermoplastic material. Welded ends of the plastic sheets are placed between two platens. The platens are heated to raise the temperature of the plastic material a sufficient amount to soften the plastic material without disturbing its molecular structure. The platens are pressed together with a sufficient pressure while applying heat until the sheets are pressed together providing a relatively smooth, continuous joint having a thickness similar to the thickness of a single sheet. Finally, the platens are cooled thereby cooling the joined sheets. <IMAGE> |
