Under a condition that, of the plurality of conveyance devices (10, 11, 12, and 14), the conveyance device (10) located on a most upstream side is defined as an upstream side conveyance device, and the conveyance devices (11, 12, and 14) on a downstream side of the upstream side conveyance device (10) are defined as downstream side conveyance devices, an upper limit and a lower limit are set to the conveyance speed of each of the downstream side conveyance devices (11, 12, and 14).

Provided is a method of producing a glass roll 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 a step of 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 (23), and leading the wound thread-like peeled material (Ge) in a predetermined conveying direction (PX) by a leading device (24).

Provided is a manufacturing apparatus (1) for a glass sheet, including roller pairs (5), which are configured to convey a glass ribbon (G) downward while sandwiching the glass ribbon (G) from both front and back sides, and are arranged in a plurality of vertical stages, wherein each of rollers forming each of the roller pairs (5) is formed so as to be movable between a sandwiching position for sandwiching the glass ribbon (G) a retracted position that is separated from a conveyance path (P) of the glass ribbon (G) and is capable of preventing contact of flying objects flying from above, and wherein, when the glass ribbon (G) during conveyance is damaged, the roller (5a) that is positioned below a damaged part of the glass ribbon (G) moves to the retracted position.

An apparatus for processing a glass web can include a gas nozzle to generate a curtain of gas to entrain debris generated during a separation procedure. In further embodiments, apparatus for processing a glass web includes a washing device including a housing with a partition dividing an interior of the housing into a first area and a second area. In still further embodiments, apparatus for processing a glass web includes a coating chamber positioned down-stream from a washing device, wherein the coating chamber includes at least one port configured to dispense a coating on at least one major surface of the glass web. Methods can include entraining debris generated during a separation procedure into a gas curtain. Further methods include washing a glass sheet within a housing including two interior areas and coating a washed glass sheet with a protective coating.
