To provide: a guide roller, whereby a replacement operation time can be shortened, guide roller position adjustment operations are not needed, and an equipment stop time can be reduced, and which contributes to suppression of productivity deterioration; and a substrate transfer apparatus provided with the guide roller. A substrate transfer apparatus (1) is provided with transfer rollers (3); a plurality of transfer shafts (2) that are provided with the transfer rollers (3); a guide roller (5) that guides a substrate (10); and a roller holding section (6) having a supporting shaft (62) that supports the guide roller (5) at one end. A contact section (52) of the guide roller (5) in contact with the substrate (10) can be separated from other sections (a base section (51) and a nut section (53)).

A device and a process for manufacturing a bent individual glass sheet including a peripheral compression belt, wherein the process includes the heating thereof to its bending temperature in a furnace, the individual bending thereof, and the general cooling thereof. One zone of the sheet at least partially inside the peripheral compression belt, referred to as locally cooled zone, undergoes, after the heating of the sheet, a local cooling faster than the general cooling, when the sheet is at a temperature of at least 530? C. The cutting of the sheet on the locally cooled zone creates edges having edge compressive stresses.

A glass sheet used in the making of an aircraft windshield is shaped using the cut-to-size method instead of the out-after-bend method. In a preferred aspect of the invention the cut-to-size method is practiced using a bending iron having a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position.

A frame for supporting a sheet of glass, referred to as a suction frame, includes a contact path for receiving the periphery of the underside face of the sheet of glass, and includes a suction system able to apply suction to the underside face of the sheet in order to enhance the retention of the sheet by the frame. This frame may form part of a device for the hot-bending of the sheet and convey the sheet with high acceleration or deceleration through a heating enclosure for the purposes of the hot-bending of the sheet.

Provided is a method of manufacturing a glass film, including: a forming step of forming a band-shaped glass film (1); a conveyance direction changing step of changing a conveyance direction of the band-shaped glass film (1) from a vertically downward direction to a horizontal direction by conveying the band-shaped glass film (1) along a curved conveyance path (R1); and a horizontal conveyance step of conveying the band-shaped glass film (1) in the horizontal direction along a horizontal conveyance path (R2), wherein, when some sections of the band-shaped glass film (1) are to be discarded, the method involves: a separating step of separating a discard glass part (1x) from the band-shaped glass film (1) on the horizontal conveyance path (R2); and a discarding step of discarding the separated discard glass part (1x) by causing the discard glass part (1x) to leave the horizontal conveyance path (R2) downward.

A process for manufacturing a bent individual glass sheet including a peripheral compression belt, the process including heating a glass sheet to its bending temperature in a furnace, performing an individual bending of the glass sheet, and performing a general cooling of the heated glass sheet, applying to one zone of the glass sheet at least partially inside the peripheral compression belt, which forms a locally cooled zone, after the heating of the glass sheet, a local cooling faster than the general cooling, when the glass sheet is at a temperature of at least 530? C.

Provided is method of producing a glass roll, the method including: a conveying step of conveying a glass film (G) along a longitudinal direction thereof; a cutting step of irradiating the glass film (G) with a laser beam (L) from a laser irradiation apparatus (19) while conveying the glass film (G) by the conveying step, to thereby separate the glass film (G) into a non-product portion (Gc) and a product portion (Gd); and a take-up step of taking up the product portion (Gd) into a roll shape, to thereby form a glass roll (R). The cutting step includes winding a thread-like peeled material (Ge) generated from an end portion of the product portion (Gd) in a width direction around a rod-shaped collecting member (20a), to thereby collect the thread-like peeled material (Ge).

The present invention relates to a mold including a master mold having a first region master mold molding surface having a shape corresponding to a first region of a molded body, and a second region master mold molding surface having a shape corresponding to a second region of the molded body, and in which the master mold includes: an inner mold having the first region master mold molding surface; an outer mold having an accommodating concave portion capable of accommodating the inner mold therein and the second region master mold molding surface on at least a part of an outer edge of the accommodating concave portion; and a buffer material provided between the inner mold and a bottom surface of the accommodating concave portion, the buffer material being pressed and deformed with relative movement of the inner mold and the outer mold.

The invention relates to a device for bending sheets of glass, comprising an upper bending form and a bending support, the upper bending form and/or the bending support being laterally mobile relative to one another, the bending support comprising a pre-bending mold for the gravity bending of a sheet of glass and a press-bending mold configured for pressing the sheet of glass against the upper form, of these two molds of the bending support one being surrounded by the other when viewed from above, at least one of these two molds of the bending support being able to be given a relative vertical movement with respect to the other.
