Method in which at least one operation is executed on hot glass resting on a support.

摘要

The process for forming and/or hardening hot glass, is claimed. The hot glass rests on a support (1) and a coating (2) consisting of heat-stable fibers is interposed between the support and the glass. A relative movement between the glass and the coating is formed during forming and/or hardening step. The coating has lines of support (3), whose directions are oriented according to the direction of shifting of the glass with respect to the coating. The support is a framework formed of beams (4) and rails (5), and the lines of support are oriented orthogonally to the beams and rails. The process for forming and/or hardening hot glass, is claimed. The hot glass rests on a support (1) and a coating (2) consisting of heat-stable fibers is interposed between the support and the glass. A relative movement between the glass and the coating is formed during forming and/or hardening step. The coating has lines of support (3), whose directions are oriented according to the direction of shifting of the glass with respect to the coating. The support is a framework formed of beams (4) and rails (5), and the lines of support are oriented orthogonally to the beams and rails of the support frame. The hot glass is transformed to a conveyor in which the support is constituted by the conveyor. The coating is constituted by a fabric made of the thermostable fibers. The lines of support extend parallel to each other. A central part of lines of support is intended to support the glass in a first direction of the fabric. Linking threads (7) of the fabric are orthogonally directed towards the lines of support along a second direction of the fabric ensuring the link of support lines between each other. The support lines are constituted either by several elongated components different from fabric or by continuous elongated components of the extending fabric periodically along the second direction and the first direction to constitute the lines of support. The linking threads are located mainly on the face of the tissue contacting with the support. Each elongated component is a strand of threads, an elastic tricot such as tubular mesh for cavalry twill providing to the tissue elasticity along the first direction, and a braid of threads. The fabric is a rectangular filet opening between the linking threads, and has two elongated components extending in parallel in the same plane of the fabric to increase the surface of the support of the fabric, or in a stacked manner to increase the thickness of the fabric. The lines of support have sides with dimensions of 1-50 mm. The fabric is present in the form of a strip extending along the beams and rails of the support frame. The successive lines of support belonging to the same elongated component are adjoined at the level of two sides of the fabric through the elbows of the elongated component. The strip of fabric is fixed tightly on the support frame by crocheting the elbows on the pins of the frame positioned along the beams and rails of the support framework by retreating the upper surface of the support of the frame. The heat-stable fibers are metallic and mixed with synthetic fibers such as poly-p-phenylenebenzobisoxazole or aramid and with mineral fibers such as glass, E-glass, silica or basalt. An independent claim is included for a temperature-resistant coating designed to be interposed between a support and a hot glass.
