The present invention relates to a method for the production of at least one three-dimensional layer of solid material, in particular for usage as wafer, and/or at least one tree-dimensional solid body. The inventive method preferably comprises the following steps: Providing a work piece for removing of layers of solid material and/or the solid bodies, wherein the work piece comprises at least one exposed surface, generating defects inside the work piece, wherein the defects define at least one crack directing layer, wherein the crack directing layer describes at least one three-dimensional contour; attaching or generating a receiving layer at the exposed surface of work piece by forming a composite structure, thermal treating of the receiving layer for generating stresses inside the work piece, wherein the stresses are causing a crack propagation inside the work piece, wherein a layer of solid material or a three-dimensional solid body is separated along the crack directing layer due to the crack propagation, wherein a surface of the layer of solid material or a surface of the solid body corresponds to the three-dimensional contour of the crack directing layer.

An adapter device for ceramic cutting machines (2) that includes an adapter plug (1) for the hole (8) of the tool holder (7) of a ceramic cutting machine (2. The plug (1) includes a hollow cylindrical shape with a stop (12) that performs an axial fixation in a direction of the plug (1) in the hole (8) of a tool holder (7) of the ceramic cutting machine (2); and a longitudinal slot (13) that leaves open the inner hollow space of the plug (1) along its entire length. The longitudinal slot (13) has a narrower segment in a part of the plug (1) that is nearest the end (21) having the stop (12), and a wider segment in the part of the plug (1) that is near the end (22) of the plug (1) opposite the stop (12).

Separator device applicable to manual ceramic cutters, which comprises: a tilting lever (2) and an actuation cam (3) provided with a cam profile (3) with a non-uniform variation in its radius of curvature and that provides a variable relationship between the rotation of the cam and the movement of the first end of the tilting lever, depending on the rotational position of the cam, in such a way that:—when the cam (3) rotates (β1) with a certain amplitude in an initial segment of its path, the first end of the tilting lever (2) completes a movement (d1) of a certain length; and—when the cam rotates (β2), with the same amplitude as β1, but in the final segment of its path, the first end of the tilting lever (2) completes a movement (d2) that is longer than the movement (d1).

A tile cutter having a base frame with a base plate and a guide which is disposed above the base plate and along which a slide carrying a cutting tool is displaceable in order to produce a score on the surface of a tile resting on the base plate, and having a breaker jaw device which is gear-coupled to the slide and is lowered onto the surface of the tile in the end phase of the displacement of the slide in order to break the tile along the score. The breaker jaw device and the slide interact with one another via a control flank arrangement in order to lower the breaker jaw device.

An apparatus for trimming stone and brick is disclosed. The apparatus is comprised of flat sections which radiate from a central axis. Each of the flat sections has two cutting edges, for a total six cutting edges. In use, the apparatus is placed onto a supportive platform so two of the flat sections contact the platform, while the third extends up and is an apical striking platform. The mason holds a stone or brick so it rests on one of the cutting edges of the apical striking platform and strikes the top face of the stone or brick with a hammer, approximately over where the stone or brick contacts the edge of the trimmer. In addition to providing a cutting surface, the subject matter of this application reduces errant vibration caused by the striking which can result in irregular cutting.

Providing a solid body to be split into a number of layers of solid material, introducing or generating defects in the solid body in order to determine a first detachment plane (8) along which a first layer of solid material is separated from the solid body, providing a receiving layer for holding the layer of solid material on the solid body, applying heat to the receiving layer in order to generate, in particular mechanically, stresses in the solid body, due to the stresses a crack propagating in the solid body along the detachment plane, which crack separates the first layer of solid material from the solid body, then providing a second receiving layer for holding another layer of solid material on the solid body reduced by the first layer of solid material, introducing or generating defects in the solid body in order to determine a second detachment plane (9) along which a second layer of solid material is separated from the solid body, applying heat to the second receiving layer in order to generate, in particular mechanically, stresses in the solid body, due to the stresses a crack propagating in the solid body along the second detachment plane, which crack separates the second layer of solid material from the solid body.

An apparatus for working a sheet material has a supporting frame, a supporting head connected to the supporting frame, a plurality of tools supported on a working device, a waterjet cutter, first and second male fast-couplers, and first and second female fast-couplers disposed on the supporting head.
