A method of manufacturing a glass sheet includes a start point forming step of forming a scribe line on a preset cutting portion of a glass sheet, a setting step of causing, through use of a support member having a groove-shaped recess, the support member to support the glass sheet having the scribe line formed thereon from one surface side so that the preset cutting portion is arranged on the recess, and a cutting step of generating a negative pressure in the recess to bend the preset cutting portion on the recess so that the one surface side protrudes, to thereby cut the glass sheet along the preset cutting portion with the scribe line as the start point. At the time of performing the cutting step, the entire recess is covered with a cover member from another surface side of the glass sheet through intermediation of the glass sheet.

Provided is a glass film manufacturing method in which manufacture-related processing is performed on a glass film while the glass film (G) is conveyed, the glass film manufacturing method comprising the step of conveying the glass film (G) on a suction roller (46), wherein the suction roller (46a) is configured to suck only a center portion of the glass film in a width direction of the glass film (G).

The present invention relates to devices for cutting tile and scoring concrete masonry units. These devices may function without generating large amounts of dust, while still allowing high-throughput cutting and scoring. The present invention features devices for cutting tile that may allow for multiple tiles to be cut simultaneously, thus boosting efficiency. The present invention features devices for scoring concrete masonry units that may enable precision scoring of multiple faces of the CMU. After the CMU is scored by the device of the present invention, it may be easily split along the scoring plane by hitting the top of the CMU with a hammer.

A cutting tool includes a cutting-wheel handle with an uniform cross-section with an outer contour including points arranged following two opposed straight rows and points arranged following one or more curved line segment of the edge of a circle enclosing an area into which the opposed straight rows lie and a cutting wheel mounted on the cutting-wheel handle to rotate along a rotation plane parallel or substantially parallel to the two opposed straight rows. A cutting-wheel handle holder has a body including a through hole for the insertion therethrough of the cutting-wheel handle, to a cutting assembly including the cutting tool and the cutting-wheel handle holder, and to a ceramic cutting device including the cutting assembly pivotably mounted to a support movably mounted on longitudinal guides mounted to a base.

A method and device for manufacturing a bevelled stone, particularly for a timepiece are disclosed. A precursor is produced from a mixture of at least one material in powder form with a binder. The method includes pressing the precursor so as to form a green body, using a top die and a bottom die comprising a protruding rib, sintering the green body so as to form a body of the future stone in at least one material, the body including a peripheral face and a bottom face provided with a groove, and machining the body including a substep of planning the peripheral face up to the groove, such that an inner wall of the groove forms at least a flared part of the peripheral face of the stone.

A worktable for tile cutter with water drainage assembly includes a movable platform and a pivotable guiding member. The movable platform has a drainage channel defined therein. The guiding member has a diversion channel defined therein and communicated with the drainage channel. The guiding member has a first diversion opening and a second diversion opening respectively located on two ends thereof. When the movable platform is in a first position, the first diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel through the first diversion opening to a water collection tank located under the movable platform. When the movable platform is in a second position, the second diversion opening is inclined downwards such that the diversion channel guides the water from the drainage channel to the water collection tank. Therefore, the draining worktable can provide a good drainage effect.

A cutting tool includes a base having a table surface. The table surface has a circular turntable and a cutting platform connected with respect to the circular turntable. The cutting platform is rotatable about an axis of the circular turntable. At least one connector releasably locks the cutting platform to the turntable at a number of positions about the axis. A blade housing and blade are suspended above the cutting platform. A handle is attached to the cutting tool to raise and lower the blade. The handle is rotatably supported by a cam integrated with the blade housing.
