Abstract: A method of making a press felt, and a press felt. The press felt comprises a continuous base fabric in the lateral direction, and at least one batt fiber layer. The closed-loop base fabric is made of longitudinal and transverse yarns. The properties of the press felt, such as permeance, are arranged to be different in edge portions of the press felt from the midportion of the felt.

Abstract: Device for measuring the condition of a felt (4) in a paper machine and for reconditioning it, comprising a measuring head (7) provided with a suction chamber (7b) and a measuring surface (7a) to be positioned against the surface of the felt (4) and provided with suction holes (15) leading into the suction chamber (7b); a suction conduit (17) leading out of the suction chamber (7b) and communicating with a vacuum source (9) for sucking air and water through the suction holes (15) from the felt (4) into the suction chamber (7b) and for discharging water and air from the suction chamber (7b); and measuring means (18) for measuring the vacuum pressure in the suction chamber (7b). In the reconditioning and measuring device according to the invention, the measuring head (7) comprises two suction conduits (16, 17) for sucking water and air, respectively.
