A sheet sticking apparatus includes a sticking unit that sticks a sheet to a workpiece held by a chuck table and a cutting unit that cuts the stuck sheet. The cutting unit includes a cutting blade that cuts the sheet, a movement unit that raises and lowers the cutting blade from and toward the chuck table or moves the cutting blade along the outer circumference of the workpiece, and a cleaning part that removes adhering things of the cutting blade. The cleaning part is disposed on the trajectory of the cutting blade that moves by the movement unit and executes cleaning by coming into contact with the cutting blade that moves.

A method for treating a solid layer includes: providing a multi-layer assembly having a carrier substrate and a solid layer bonded to the carrier substrate by a bonding layer, the solid layer having an exposed surface including a defined surface structure, the defined surface structure resulting from a removal, which is effected by a crack, from a donor substrate, at least in sections; processing the solid layer, which is arranged on the carrier substrate; and separating the solid layer from the carrier substrate by a destruction of the bonding layer.

Aspects of the invention may be directed to a method of creating a predetermined structure from a diamond bulk. In some embodiments, the method may include: irradiating the diamond bulk with at least one laser having a focal point at a predetermined location, the laser may create graphitization at locations where the focal point of the laser engages the diamond bulk; at least one of: moving the diamond bulk to be positioned with the focal point of the laser within the diamond bulk, and moving the at least one laser such that diamond bulk be positioned with the focal point of the laser, along at least one axis wherein the movement corresponds to a predefined scheme; removing of the graphite from the diamond bulk; and extracting the predetermined structure from the diamond bulk.

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 levering structure for a ceramic cutter device including a main body assembly and an actuator element. The main body assembly includes a first and a second body structure, both being pivotably connected to each other by a first articulation, so that a first and a second pivoting end positions are defined. The actuator element is pivotably connected to the first body structure and includes a curvilinear base in contact with a contact pivot shaft transversally arranged on the second body structure, the curvilinear base defining a first and a second leverage positions. The levering structure is configured such that when the first body structure is pivoted from the first to the second pivoting end position, the pivoting movement of the first body structure causes the actuator element to move from the first leverage position to the second leverage position.

The present invention relates to a cutting method and a cutting device for the superficial scoring of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, and to a method for dividing of, preferably plate-shaped, components made of glass or ceramics, preferably of glass sheets, for example of float glass sheets or laminated glass sheets, in particular laminated safety glass sheets, into individual component cuttings, preferably glass sheet cuttings.
