Abstract
PURPOSE: To positively weld opposite edges of a heat shrinkable sheet by heat with them registered, by providing two projections on one of a set of heating plates, and two mating holes on the other, and inserting the projections into openings in parts of the opposite edges to be welded with the opposite edges lapped by rolling the sheet into a cylinder.
CONSTITUTION: One of the set of the heating plates 1, 3 is provided with two projections 2 and the other is provided the mating holes 4. The parts 6 of the opposite edges of the heat shrinkable sheet 5 where they are to be welded are provided with the openings 7 through which the projections 2 will be inserted. The openings 7 in one end of the heat shrinkable sheet 5 are engaged with the projections 2 on the heating plate 1, and then the sheet 5 is rolled with the other openings 7 engaged with the projections 2. Then the parts 6 to be welded are welded by heat under pressure using the set of the heating plates 1, 3. As the heat shrinkable tube is formed into a tube shape, after it has been removed from the heat welding apparatus, it can be heat shrinked. Thus the width of the parts to be welded is stabilized by the projections on the heating plate so that they are positively registered and welded by heat.
