发明名称 MANUFACTURE OF CORRUGATED FIBERBOARD MOLDING
摘要 PURPOSE:To make it possible to prepare a corrugated fiberboard molding without occurrence of wrinkle and tear and where adhering of a skin material can be finished by means of one stroke method by forming slits and cutouts in advance on a linear of a fiberboard, fixing temporarily it by placing an adhesive on the remained part of the fiberboard, fixing temporarily a supplementary sheet to the linear by placing a thermofusible adhesive between them to form a fiberboard blank and heat-molding this blank. CONSTITUTION:To manufacture a molding, a combination, so-called single-state fiberboard, wherein a core 1 and the first liner 2 are bound with a thermofusible adhesive 4 and the second liner 3 a surface of which is coated with a thermofusible adhesive 4 and which is separated with said combination are provided. Slits S and cutouts N are formed in advance on this second liner 3 and in addition a supplementary sheet 5 with an adhesive 4 is adjoined to the linear 3. These materials are combined together and temporarily fixed. This blank 8 is press-molded while it is heated between a fixed mold adjoining to the liner 2 and a movable mold adjoining to the supplementary sheet 5. In this molding, occurrence of wrinkle and tear is prevented by slits and cutouts.
