Abstract

PURPOSE:To improve material yield of paper material by providing many cuts from one of the long sides of a rectangular paper material toward the opposing side, disposing the other side in a circle along the inner circumference of a circular plate, and attaching the paper material to the plate surface. CONSTITUTION:After a paper material 1 in the form of a sheet is made, it is cut into plurality of rectangular paper materials 2, and many cuts 5 are provided from one long side 3 toward the other side 4. This rectangular paper material 2 is disposed in a circle with the other side 4 without including cuts 5 placed along an inner circumference 7 of a circular plate 6, and the side 3 including the cuts 5 is expanded along an other circumference 8 of the plate 6, and both are attached to each other to form a wet type friction material 9. The friction material 9 can thus be manufactured using 100% of the paper material 1. If the paper material 1 is made in the form of a rectangular sheet, it can be cut into rectangular paper materials 2 without waste, thereby material yield is improved.
