ABSTRACT:
A joint construction formed by sonically welding the edges of sheets of oriented nylon. The coextensive edge portions of the nylon sheets are formed with generally complementary surfaces which are at an acute angle to the flat surfaces. A plurality of ridge portions extend from the complementary surfaces substantially parallel to the adjacent edges and concentrate sonic energy introduced into the joint at the interface of the complementary surfaces to form a weld joining the sheets, with the thickness of the completed joint being substantially the same thickness as an individual sheet.
