Title:
FEED BLOCK AND SHEET MANUFACTURING DEVICE PROVIDED WITH SAME, AND METHOD FOR MANUFACTURING SHEET
Document Type and Number:
WIPO Patent Application WO/2018/042617
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a feed block capable of stably manufacturing a resin sheet in which a main material and a sub-material are laminated together. The feed block supplies to a die a molten-resin laminate P in which at least one main material A made of plate-shaped or sheet-shaped molten resin and a sub-material B made of plate-shaped or sheet-shaped molten resin are laminated together. In the laminate P, the sub-material B is laminated in at least a part in a width direction W of the at least one main material A. The feed block has at least one main material molding flow path 17, 18 causing molten resin to flow to mold the main material A into a plate or sheet shape, a sub-material molding flow path 19 causing molten resin to flow to mold the sub-material B into a plate or sheet shape, a merging part 23 of the at least one main material molding flow path 17, 18 and the sub-material molding flow path 19 for forming the laminate P, and a laminate flow path 24 that is positioned downstream of the merging part 23 and supplies the laminate P to the die.
