PURPOSE:To obtain an endless felt having the seamed part with the same thickness, density and water-absorption as those of the other part, by staggering the end part of each fiber butt layer in the successive lamination of fiber butt layers on a base cloth. CONSTITUTION:Loops 10A, 10A at both ends of a base cloth a is intermeshed with loops 10B at both ends of a relatively short base cloth B. Core wires 12, 13 are passed through the common hole of both loops 10A and 10B to join both base cloths A and B into a base cloth C. A plurality of fiber butt layers 21, 22, 23 are successively laminated on the base cloth C by needling. In the above procedure, both ends of each fiber butt layer 21-23 are cut with steps. After removing the core wires 12, 13, both end loops 10A, 10A of the base cloth A are intermeshed with each other to form a common hole and a core wire 16 is passed through the hole to obtain an endless felt.
