A glass plate processing system includes a first aligning means. When first and second glass plates different upper and lower surface areas are processed, the first aligning means aligns a first side edge extending in a front-rear direction on one side in a width direction of a first glass plate to be processed first with a first side edge extending in the front-rear direction on the one side in the width direction of a second glass plate to be processed later. The glass plate processing system causes the first aligning means to align the first side edge of the second glass plate at a position of the first side edge of the first glass plate to perform processing on the second glass plate. The glass plate processing system shortens a moving distance and arrival time for a processing device and shortens cycle time of processing.

A method includes introducing light into a glass article such that at least a portion of the introduced light is emitted from an edge of the glass article. The light emitted from an edge of the glass article is detected. An intensity profile of the emitted light is an intensity of the emitted light as a function of axial position. A first intensity boundary of the intensity profile and a second intensity boundary of the intensity profile are determined. A thickness of a layer of the glass article is determined based on an axial distance between the first intensity boundary and the second intensity boundary.

Methods and apparatus provide for sourcing a glass web, the glass web having a length and a width transverse to the length; moving the glass web from the source to a destination in a transport direction along the length of the glass web; cutting the glass web, at a cutting zone, along the length of the glass web into at least first and second glass ribbons as the glass web is moved in the transport direction from the source to the destination, such that respective first and second edge surfaces are produced on the first and second glass ribbons; and optically inspecting at least one of the first and second edge surfaces in real-time as the first and second glass ribbons of the glass web are moved in the transport direction to the destination.

The present application provides a device and a method for removing a residual material, wherein, the device for removing a residual material includes: a cutting-transporting portion configured to cut a bulk material; a pressing-moving portion being in contact with the cut bulk material and configured to apply a pressure to the residual material on the cut bulk material, such that the residual material is separated along a cutting line from the cut bulk material to obtain a base piece; and a splitter coupled to the cutting-transporting portion and configured to split the base piece. The pressing-moving portion is further configured to lift the base piece up to above the cutting-transporting portion, and then moving the base piece to the splitter.

The present disclosure relates to a method and device for cutting glass tubes with a length L from a glass tubing that moves at a feed rate v.sub.1. The glass tubing is investigated for defects with an analytical device. The analytical device determines whether a glass tube to be separated is either defect-free (case 1) or contains defects (case 2). In case 1, a defect-free glass tube of the length L is separated from the glass tubing. In case 2, the device and method of the present disclosure determines a distance L.sub.A in the lengthwise direction between the defect and a free end of the glass tube to be separated. The distance L.sub.A is determined from the portion of the defect at the greatest distance from the free end of the tube. The device and method of the present disclosure then separates a piece of a glass tube or a glass tube that contains defects from the glass tubing at a distance L.sub.S from the free end of the glass tube, as a function of L.sub.A.

A method for producing a glass article includes forming a glass sheet from a molten glass source and separating the glass article from the glass sheet. During the step of separating the glass article from the glass sheet, the water content of the atmosphere surrounding the glass sheet is controlled to be below a predetermined value. Such control of the water content of the atmosphere surrounding the glass article can effectively reduce the density of particles adhered thereto.
