PURPOSE:To make it possible to reduce the incidence of beat mark by a method wherein the part to be cut of a coated cloth is heated just before cutting up to a temperature, which is higher than the softening point of thermosetting resin and lower than its setting temperature. CONSTITUTION:Fust before the cutting of a coated cloth in continuous form to lengths with a cutter, the cut surface of the coated cloth is heated within a temperature range, which is higher than the melting point of thermosetting resin and lower than its setting temperature. By heating the cut surface of the coated cloth just before its cutting, the resin impregnated in a base material is brought into the softened state. When the surface is cut in this state, production of chips can be suppressed extremely. Consequently, the chips are prevented from flying in air and adhering to the surface of the constitutional material of a laminated sheet. As the thermosetting resin, general-purpose resin for laminated sheet such as phenolic resin, epoxy resin, polyester resin, polyimide resin or the like can be used. |
