Abstract

PURPOSE: To manufacture the title pipe of uniform shape as a whole, by making molten cuts on one side of the whole foamed thermosetting resin sheet, followed by fusing the sheet bent inside along the cuts.
CONSTITUTION: The thermosetting resin tape 2 coated with an adhesive is applied to one side of the foamed thermosetting resin sheet 1 with the extended parts about 30 mm long in the width direction, and the release paper 3 is applied to the extended tape to form the composite sheet 4. The heating jig 7 having built-in heating wires and the tapered parts 6aW6g of inverted triangular cross sections on the bottom is moved in the long direction of arrow A and brought into contact with the exposed surface of the foamed sheet 1 of the sheet 4 to make the molten cuts 8aW 8g on the whole exposed surface of the sheet 1. The vacuum holders 9aW9c are attached to the both ends and the center of the tape 2 in the long direction, then the holders 9a and 9c are moved in the directions of arrows B and C. The holder 9b is then moved to the direction of arrow D to fuse the cuts 8aW8g
