Abstract

PURPOSE: To manufacture an eaves trough joint in a continuous step, by laminating an expansible adjusting sheet on an eaves trough joint formed in parallel while moving them.
CONSTITUTION: A melt of a non-rigid synthetic resin, e.g. non-rigid polyvinyl chloride, is extruded through the head 6 of the extruder 10 into the sheet 1. A melt of a rigid synthetic resin, e.g. rigid polyvinyl chloride, is extruded through the head 7 into the eaves trough joint 5 and solidified. The joint 5 is sized by the die 18, and the sheet 1 is pressed by the uneven parts of the top and the bottom forces of the endless caterpillars 12 and 13 into the adjusting sheet 4 having the bellows part 2 and the eaves trough connections 3 and 3. The sheet 4 is bonded to the inner surface of the joint 5 by the unit 20 partly in the joining part 9 to give an eaves trough.
