  • Patent number: 11318767
    Abstract: A manufacturing method of a head leading member, which is provided in a printing machine including a head for discharging an ink toward a working surface, in order to lead the head in a main travelling direction, and the manufacturing method of a head leading member including: a base member fixing step in which a base member, being like a plate, is fixed to a frame extending in the main travelling direction; a guiding reference surface shaping step in which a surface of the base member, in a state of being fixed to the frame, is so manufactured as to be a plane, being along the main travelling direction, in such a way as to shape a guiding reference surface; and a guide member supporting step in which a guide member for leading the head is set in such a way that the guiding reference surface supports the guide member.

  • Publication number: 20220097322
    Abstract: The preset invention is to mold a laminate at a high accuracy by appropriately generating slippage between fiber sheets of the laminate at bending. A method for molding a laminate includes a step in which a plurality of gripping parts, which are arranged apart from each other, grip an area, wherein slippage between fiber sheets is prevented, in a plate-shaped laminate including a plurality of fiber sheets laminated each other; a step in which the plurality of gripping parts grip the area wherein slippage between the fiber sheets is prevented, while maintaining the state wherein relative moving of the area of the laminate and the gripping parts is prevented; and a step in which the gripping parts move so as to subject the laminate to bending.

  • Publication number: 20220055281
    Abstract: The purpose is to shape a laminate with high accuracy by properly causing the slipping between fiber sheets in the laminate during a bending processing of the laminate. A laminate shaping apparatus is equipped with: a holding section (2) for holding a sheet-like laminate (50) composed of a plurality of fiber sheets laminated on each other; and a slipping promotion section (3) which is arranged along a surface of a region other than a region held by the holding section (2) in the laminate (50) and is so configured as to promote the slipping between the fiber sheets in the laminate (50) during the bending processing of the laminate (50).

  • Publication number: 20220024155
    Abstract: The purpose of the present invention is to suppress generation of creases when one layer of a prepreg is molded at a time and molded layers of the prepreg are laminated one by one. A prepreg molding method comprises: a step of bending a long prepreg elongated in one direction into a downwardly convex U-shape in cross section; a step of bringing a lower part of the prepreg bent in the U-shape into contact with a bottom part of a mold having a concave cross section and mounting the prepreg on an inner part of the mold; and a step of pressing and deforming the prepreg mounted on the inner part of the mold using pressing part.

  • Publication number: 20210402674
    Abstract: The purpose of the present invention is to provide: a composite material which when bent and formed, can prevent the occurrence of problems such as the occurrence of wrinkles of the composite material, an increase in the number of forming steps, and difficulty in forming the composite material; and a method of forming the composite material. This composite material (1) comprises a laminate (2) in which a plurality of fiber sheets are laminated, wherein the laminate (2) has a to-be-bent portion (3) that is to be bent along a mold, and in a region (5) of the laminate (2) from an end edge (4) on a bent side to the to-be-bent portion (3), the laminate (2) is divided into a plurality of layers along the plate thickness direction of the laminate (2).
