Abstract
PURPOSE: To prevent effluence of resin in the direction of outer periphery, improve the efficiency of a work for forming a laminate and assure the uniformity of the quality of the article by sealing the circumference of end surfaces of a preimpregnation layer.
CONSTITUTION: A material for sealing effluent resin is touched on the circumference of the end surfaces of the primpregnation layer 1 prepared by laminating prescribed numbers of preimpregnation sheets and is molded under heat and pressure. The sealing material is prepared, for instance, by sticking a tape 2 of paper, cloth, a plastic film or the like in layers or the portion of the preimpregnation layer 1 from the peripheral-edge parts of the front-most surface of the end surfaces thereof, holding the portion thus processed between flat-surface plates 3, holding the same further between the sheets of buffer material 4 and heating and pressing by pressing heat boards 5. It is appropriate that the width of sticking of the tape 2 on the peripheral-edge parts of the preimpregnation layer corresponds to the peripheral- edge part to be trimmed when the laminate article is subjected to finish processing in consideration of the sealing effect and economization.
