Abstract: Provided is a glass roll utilizing a flanged roll core, and reliably inhibiting a glass film from breaking from an end portion in a width direction thereof as an origin of breakage. A glass roll (1) is formed by winding a glass film (4) and a cushion sheet (5), under a state of being superposed, around a roll core (3) including a flange (2) at each end portion thereof, in which an end portion in a width direction of the glass film (4) is separated from the flange (2) on each side in the width direction of the glass film (4), and the cushion sheet (5) is extended beyond the end portion in the width direction of the glass film (4) to the flange (2) side, to thereby form an extension portion (5a).

Abstract: Provided is a package form, with which cleanness of a glass film is ensured and the glass film is prevented from breaking. The package form is effective in minimizing the number of glass film processing steps to be performed before packaging and after unpackaging. As the package form for a glass film, provided is a glass roll (1) formed by winding a glass film (2) into a roll while superposing the glass film (2) on a protective sheet (3), the glass film (2) being formed by an overflow downdraw method and having exposed front and back surfaces.

Abstract: To provide a glass roll capable of reliably preventing a glass film from breaking from an end surface of the glass film as an origin of breakage, a glass roll (1) is formed by winding a glass film (2) into a roll while superposing the glass film (2) on a protective sheet (3), the glass film (2) being formed by an overflow downdraw method to have a thickness of 1 ?m or more and 200 ?m or less, and to have each end surface in a width direction to form a cut surface cut by laser splitting.

Abstract: A glass plate packaging pallet includes a pallet base formed by integrating a base part and a backside part rising from a rear side of the base part, and a mount body formed by integrating a pedestal part and a backrest part, the pedestal part being placed above the base part and supporting from below a plurality of glass plates disposed so as to be stacked with an upright posture, the backrest part being placed in front of the backside part and supporting the glass plates resting thereagainst, and is configured such that a rear surface of the backrest part and a front surface of the backside part are fixed together so as to face each other along the same plane, and that the pedestal part is positioned in a non-connected state with respect to the base part.

Abstract: A pallet for packing a glass plate include a base part which is disposed at a bottommost portion, for supporting from below a plurality of glass plates piled one upon another in an upright posture, and has a fork insertion portion for insertion of forks of a forklift. The pallet also has a backside part rising from a rear side of the base part, for supporting the glass plates from a rear thereof, and a pedestal part mounted in engagement with at least one of the base part and the backside part so as to receive bottom side portions of the glass plates, in which a lowermost portion of the pedestal part is set lower than a substantial top surface of the base part.

Abstract: [Solving Means] A glass plate packaging pallet includes: a pallet base (2) formed by integrating a base part (2a) and a backside part (2b) rising from a rear side of the base part (2a); and a mount body (3) formed by integrating a pedestal part (3a) and a backrest part (3b), the pedestal part (3a) being placed above the base part (2a) and supporting from below a plurality of glass plates (G) disposed so as to be stacked with an upright posture, the backrest part (3b) being placed in front of the backside part (2b) and supporting the glass plates (G) resting thereagainst, and is configured such that a rear surface (3bb) of the backrest part (3b) and a front surface (2ba) of the backside part (2b) are fixed together so as to face each other along the same plane, and that the pedestal part (3a) is positioned in a non-connected state with respect to the base part (2a) so that force of deformation of the backside part (2b) involved with deformation of the base part (2a) is received between the front surface (2ba)

Abstract: A pallet (2) for packing a glass plate includes: a base part (3) which is disposed at a bottommost portion, for supporting from below a plurality of glass plates (G) piled one upon another in an upright posture, and has a fork insertion portion (6) for insertion of forks of a forklift; a backside part (4) rising from a rear side of the base part (3), for supporting the glass plates (G) from a rear thereof; and a pedestal part (5) mounted in engagement with at least one of the base part (3) and the backside part (4) so as to receive bottom side portions of the glass plates (G), in which a lowermost portion of the pedestal part (5) is set lower than a substantial top surface of the base part (3).

Abstract: A glass member for use in a cathode ray tube is provided, which can facilitate the heating and softening of glass during sealing and raise the productivity without decreasing the mechanical strength of the product by improving the shapes of the seal end faces of the panel and funnel. In an edge area between an edge of the seal end face of each side part of the glass member for use in the cathode ray tube comprising a glass panel or a funnel and a position about 5 mm away along a tube axis from the edge, a thin edge part is formed to have a thickness decreasing part. The rate of thickness decreasing thereof toward the edge is larger than that of a standard shape in a root area adjacent to the edge area. Also, the thin edge part is formed so that an inequality of 0.3?t1/t0?0.7 is satisfied where t1 is a thickness at a position 1 mm away along the tube axis from the edge, and t0 is a thickness at a position 5 mm away along the tube axis from the edge.

Abstract: A funnel-and-neck sealing body comprises a funnel having a substantially rectangular large opening to which a panel for projection tube is sealed, and a circular small opening; and a neck tube of substantially a cylindrical shape sealed to the small opening of the funnel. The neck tube has an electron gun installing region for installing an electron gun therein, and a yoke mounting region for mounting a deflection yoke externally thereon, wherein an outer diameter of the yoke mounting region is smaller than an outer diameter of the electron gun installing region.
