Title: SHEET FOR FORMING PILLAR FOR GLASS PANEL UNIT, PILLAR MOUNTING DEVICE FOR MANUFACTURING GLASS PANEL UNITS, MANUFACTURING METHOD FOR GLASS PANEL UNITS, AND MANUFACTURING METHOD FOR GLASS WINDOWS
Abstract:
To efficiently manufacture a glass panel unit in which a pillar is sandwiched between a pair of substrates, a manufacturing method for glass panel units comprises a punching step (S2) and a pillar mounting step (S3). In the punching step (S2), a punch (4) forms at least one pillar (14) by way of punching with a punch (4), from a base material (30) of a sheet (3), at least one of a plurality of sections (31) on the base material (30), wherein the sections are surrounded by each of a plurality of ring-shaped grooves (32). In the pillar mounting step (S2), the at least one pillar (14) is mounted on the surface (110) of a first substrate (11).
