In a cleaving apparatus (1) for a glass film, an initial crack (10), which is formed at a leading end portion of a preset cleaving line (7) of a glass film (G), is propagated along the preset cleaving line (7) by a thermal stress generated in the glass film (G) through localized heating performed along the preset cleaving line (7) and cooling of a heated region resulting from the localized heating. At this time, a resin sheet (R) having higher flexibility than the glass film (G) is arranged in a cleaving region, and the resin sheet (R) is floated by blowing a gas on a lower surface of the resin sheet (R) by a floating unit (3). Then, a preset cleaving portion of the glass film (G) including the preset cleaving line (7) is lifted and supported while being covered with the floated resin sheet (R) from below, and in this state, the glass film (G) is cleaved.

This invention concerns a process for producing a curved, laminated safety glass sheet from a first curved glass sheet (1), a first laminated layer (2), a thermoplastic substrate sheet (4) with a biaxially drawn thin-layer system (3), a second laminated layer (5), and a second curved glass sheet (10) conforming to the first one. To avoid formation of folds in the substrate layer, the process has the following steps: (a) a prelaminated sheet consisting of the first laminated layer (2) and the substrate sheet (4) is superimposed with its laminated layer facing the first glass sheet, (b) a bend-resistant cover sheet (10) conforming to the first glass sheet (1) is superimposed on the prelaminated sheet, (c) the glass layer packet formed out of the first glass sheet (1) and the prelaminated sheet with the cover sheet (10) superimposed upon it is preliminarily bonded by removing the air and subjecting it to pressure and heat, (d) the cover sheet (10) is removed, (e) the second laminated layer (5) and the second glass sheet (10) are superimposed on the preliminarily bonded glass-film pocket, (f) the laminate so formed is preliminarily bonded by removing the air and subjecting it to pressure and heat, (g) the preliminarily bonded laminate is finally bonded into a laminated safety glass sheet by subjecting it to pressure and heat.

A glass film laminate is manufactured by setting a surface roughness Ra of a surface of a glass film having a thickness of 200 μm or less to contact a support glass, which supports the glass film, and a surface of the support glass to contact the glass film to 2.0 nm or less, and by bringing the surfaces of the glass film and the support glass into surface contact with each other. After that, a laser scribing operation is carried out, in which a scribe line is formed in the glass film by propagating an initial crack through laser heating of the glass film followed by subsequent cooling of the glass film.

Provided is a glass roll formed by winding a glass film into a roll, in which a minimum winding radius of the glass film is optimized. Thus, the glass film is reliably prevented from breaking due to static fatigue, and is able to be stored for long periods. A glass roll (1), which is formed by winding a glass film (2) into a roll, has a configuration in which the glass film has a minimum winding radius (R) satisfying the following relation: R≧(T/2)[(2.3/σ)×E−1], where σ represents flexural strength of the glass film (2) obtained by a 3-point bending test, T represents a thickness of the glass film, and E represents a Young's modulus of the glass film.

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 μm or more and 200 μm or less, and to have each end surface in a width direction to form a cut surface cut by laser splitting.

Filling of narrow and/or high aspect ratio gaps and trenches with silicate glass is accomplished at reduced temperatures and without reflow by etching the glass concurrently with thermal chemical vapor deposition of the glass such that the deposition rate will exceed the etching rate by a relatively small net deposition rate near the surface with the excess deposition rate increasing over the depth of the trench or gap. The as-deposited glass film is made dense and stable by carrying out the concurrent etch and deposition process at an elevated temperature but which is within the maximum temperature and heat budget which can be tolerated by structures formed by previously performed processes. Fluorine can be incorporated in the silicate glass film as a dopant in sufficient concentration to reduce dielectric constant of the film. Phosphorus and/or boron can be incorporated into the film, as well, and may enhance void-free filling of trenches and gaps.

The glass film laminate comprises a glass film and a supporting glass. The glass film and the supporting glass have surfaces being brought into contact with each other, and each of the surfaces has a surface roughness Ra of 2.0 nm or less.

A film laminating adhesive is formed by admixing a polyester resin and encapsulated metallic flakes. The metallic flakes are encapsulated with a silane in a hydrolyzed condition modified with a surfactant or dispersion agent. A mounting adhesive is applied to an outside surface of a first clear PET film. A silicone liner is adhered to the outside surface. A second PET film is bonded to another side of the first clear film with the film laminating adhesive containing encapsulated metallic flakes to form the spandrel glass film composite adapted for bonding to a glass surface after removal of the silicone liner.

Composite materials that can be used to block radiation of a selected wavelength range or provide highly pure colors are disclosed. The materials include dispersions of particles that exhibit optical resonance behavior, resulting in the radiation absorption cross-sections that substantially exceed the particles' geometric cross-sections. The particles are preferably manufactured as uniform nanosize encapsulated spheres, and dispersed evenly within a carrier material. Either the inner core or the outer shell of the particles comprises a conducting material exhibiting plasmon (Froehlich) resonance in a desired spectral band. The large absorption cross-sections ensure that a relatively small volume of particles will render the composite material fully opaque (or nearly so) to incident radiation of the resonance wavelength, blocking harmful radiation or producing highly pure colors. The materials of the present invention can be used in manufacturing ink, paints, lotions, gels, films, textiles and other solids having desired color properties. The materials of the present invention can be used in systems consisting of reflecting substances such as paper or transparent support such as plastic or glass films. The particles can be further embedded in transparent plastic or glass beads to ensure a minimal distance between the particles.
