摘要:
A method and apparatus for the separation of round or elliptical bodies from the surrounding material or for annular shaped bodies from the material sorrounding the OD as well as the material confined by the ID. The method applies to non-metallic substances under special consideration of glass.

A wall-mounted support system for a sheet-cutting machine employs a workpiece clamping unit, and a set of rack units to provide endwise support for the workpiece. The clamping unit is comprised of confronting, elongated members of U-shaped cross section, connected by pairs of identical pivot arm components which are, in turn, assembled with pins that provide bearing elements. The rack units incorporate leveling bars, the attitudes of each of which is adjusted by use of an eccentric fixture.

A method of manufacturing a glass sheet involves forming a scribe in one surface of a glass sheet having a rectangular shape on a periphery of an edge portion of the glass sheet in parallel to the edge portion, and cutting the glass sheet along the scribe as a boundary. The method includes forming the scribe in a region other than both end portions of the glass sheet in a direction along the edge portion; and cutting the glass sheet along a bending portion in which the glass sheet is locally bent, the bending portion being continuously formed in a state of being connected to the scribe and gradually protruding from an edge portion side to an inner side as being shifted away from the scribe.

Methods and apparatuses for separating sheets of brittle material are disclosed. According to one embodiment, a separation apparatus for separating a sheet of brittle material includes a first separation cam positioned adjacent to a sheet conveyance pathway and a second separation cam positioned opposite from and downstream of the first separation cam. The first and second separation cams may be rotated such that the contact faces of the separation cams periodically extend across a centerline of the conveyance pathway. Rotation of the first and second separation cams may be synchronized such that at least the portion of the contact face of the first separation cam and at least the portion of the contact face of the second separation cam periodically extend across the centerline of the conveyance pathway at a separation time and periodically do not extend across the centerline of the conveyance pathway at a non-separation time.

Methods for cutting of raw glass slabs into a number of glass cuttings include determining the supply of uncut or partially cut raw glass slabs, continuously detecting incoming cutting orders and processing of the cutting orders, continuously determining an optimized processing order and optimized cutting patterns of raw glass slabs based on determined values, processing cutting orders according to the determined optimized processing order and optimized cutting patterns, and storing the glass cuttings in assigned compartments of an intermediate storage. An increased productivity with minimized waste of material can be achieved by the continuous optimizing method in regards to the temporal sequence and cutting patterns of the glass cuttings.
摘要:
A method and machine whereby a sheet of glass, held on a table of the machine, is first scored to form at least one score line, and is then broken along the score line by transmitting vibratory action to the sheet, about the score line.
