Abstract

PURPOSE: To enhance mechanical strength of a seal surface of a seal packing by a method wherein a side wall paper is provided to a rectangular folded filter paper body and a seal packing having a continuous layer of a high and a low density is formed to this periphery.
CONSTITUTION: In order to prepare the titled filter body for an air purifying device of an internal combustion engine, the side wall paper 2 is adhered to a side surface of rectangular filter body 1 made of folded sheet like filter paper to obtain a filter body 6. This filter body is placed on an inner peripheral wall 7 of a lower mold 11 forming a groove portion 9 between an inner and on outer peripheral wall 7, 8 and for raw materials for polyurethane are ejected into said groove portion 9 and an upper mold 12 is placed on a surface of the outer peripheral wall 8 of the lower mold to expand the aforementioned raw materials. In this case, it is necessary to set a mold temp. to a predetermined value wherein the temp. of the lower mold 11 is higher as compared to the upper mold 12. The seal surface of a seal packing 3 of the square shaped filter body forms the high density layer 4 with high mechanical strength to prevent cracks from being generated. The low density layer 5 has high elasticity to ensure the seal function.
