PURPOSE:To facilitate the replacement of a machine-glazed paper sheet by forming a hole onto a flange fitted into the paper core part of a machine-glazed paper sheet and inserting an elastic body having a pin at the top edge and forming the peripheral groove for the engagement with the pin onto a shaft supported onto the flange. CONSTITUTION:The captioned apparatus is constituted of a pair of flanges 12 and a pair of shafts 13, and a fitting part 14 for the insertion into the paper core part 7 of a machine-glazed paper sheet 5 is formed onto the flange part 12, and a penetration hole 15 which extends in the longitudinal direction of the paper core part 7 is formed onto the fitting part 14. The shaft 13 penetrates into the penetration hole 15 and is supported in slidable ways by the fitting part 14. Onto the fitting part 14, a hole 16 is formed vertically in the axial direction of the shaft 13, and a spring 17 is fixed into the hole 16, and an engagement pin 18 is installed at the top edge of the spring 17. While a plurality of peripheral grooves 19 are formed at the position corresponding to the width of a variety of machine-glazed paper sheets, onto the shaft 13. When the machine-glazed paper sheet is replaced, the flange 12 is demounted, and the engaging pin 18 is engaged with the peripheral groove 19. |
