摘要:
The machine (1) brings about artificial ageing of products (2) for building purposes and comprises a path (3) along which the products (2) are channelled, and a station (7) for ageing of the products (2), which is defined along a stretch of the path (3). The main characteristic of the present invention consists in the fact that the ageing station (7) comprises at least one rotating roller (13) with axis of rotation orthogonal to the direction of advance of the products (2) and at least one projection (18) made on the roller (7) and designed to come into contact with the products (2) in order to erode and hence age them.

A method of drilling through a masonry structure 20 includes the steps of providing a drill 10 and using the drill 10 to drill a bore 18 in the masonry structure 20. The method also includes a step of providing a reaction member in the form of a lever 28 and causing engagement of the lever 28 with the masonry structure 20 and with the drill 10 within the masonry structure 20 such that the lever 28 may provide a reaction force to assist the movement of the drill 10 through the structure 20 as it drills the bore 18.
摘要:
A method for producing laminar elements (8), comprises preparing an elongated body (1) and cutting said elongated body (1) according to a plane substantially transverse to a longitudinal direction of said elongated body (1), and further comprises obtaining said elongated body (1) with a transverse section substantially corresponding to the outline of a front face (13) of said laminar elements (8).
摘要:
The system of modular elements comprises a plurality of disc elements (11, 12,...) with diamond outer rings (11a, 12a,...) for assembling on a single drive spindle with a spacing approximately equal to their thickness; mechanical fragmenting means (19, 20, 21, 22,...) being provided in the spaces between the disc elements to operate essentially by impact, in contrast to the abrasive action of the diamond outer ring of the said disc elements; which disc elements have different diameters forming a broken line that corresponds substantially to the outline of the profile or shaping to be produced on marble, stone or the like; the arrangement being such that the disc elements (11, 12,...) cut grooves by diamond abrasion and the mechanical fragmenting means (19, 20, 21, 22,...) shatter the parts projecting from the grooves with an action of fragmentation by impact and by brittle fracture.
摘要:
The rotary tool for producing profiles or cuts in hard fragile materials such as marble, granite, stone, glass and the like comprises at least one rotationally symmetrical body (1, 2) involving a configuration defined by the envelope of a multiplicity of circular parts (6-13) externally provided with diamond means. The circular parts are separated by grooves (20 to 25) and the configuration corresponds as a negative of profiles or cuts to be produced in the above-mentioned hard fragile materials, the arrangement being such that the production of profiles or cuts is effected jointly by abrasion on the part of the diamond means and by fragile-fracture breaking on the part of the grooves, and possible breaker inserts (30) with a metal pin which is hard or covered with industrial diamond.
摘要:
Elektrische Schneidvorrichtung, insbesondere für Kurvenschnitte im Trocken- oder Nass-Schnittverfahren für Fliesen, Naturstein, Kunststein, Betonplatten u.dgl., mit einem Winkelschleifer (Flex), versehen mit einer an das zu schneidende Material angepassten Trennscheibe, oder einer Stichsäge als Schneidorgan oder einem Motor mit Trennscheibe und mit einer tischartigen Materialunterlage sowie wahlweise einem Wasseraufnahmebehälter und einer Wasserzufuhreinrichtung für das Schneidorgan. Da die Herstellung gebogener oder gekrümmter Schnitte bisher nur mit für derartige Zwecke speziell geeigneten bzw. ausgestatteten Schneidvorrichtungen oder mittels an derartigen Vorrichtungen angebrachter Schablonen möglich gewesen ist, wird zur Vereinfachung und insbesondere Verringerung des Kostenaufwands vorgeschlagen, dass die Schneidvorrichtung (1, 2, 3) auf einer insbesondere gebogenen Laufschiene (4) und/oder Führungsschiene (34) und/oder Kurvenschablone am Ende eines um einen Drehpunkt zirkelartig verschwenkbaren Arms (5, 7) verfahrbar bzw. verstellbar angebracht ist, wobei der Schnittwinkel frei einstellbar ist.
摘要:
A method for manufacturing antique mosaic tesserae, comprising the steps of:
placing a slab-like matrix (5) under a cutting unit (1), arranging the matrix (5) upside down so that the exposed face is directed away from the unit; scoring the laying side along at least two directions and to a preset and adjustable depth, creating preferential fracture lines (6); fracturing the slab-like matrix (5) scored on the laying face; and tumbling the resulting tesserae in order to round their edges.
摘要:
A stone cutting method for cutting stone used as a tile that is used for a pavement or a floor comprising the steps of positioning and placing on a table (21) a lower protection plate (20) to which a lower elongate cutting protrusion (30) that is formed into a predetermined configuration is attached, then placing a stone to be cut on said lower elongate cutting protrusion (30) on said lower protection plate (20), positioning and placing an upper protection plate (18) on which an upper elongate cutting protrusion (30a) that is formed similar in shape to that of said lower elongate cutting protrusion (30a) is attached, and pressing down said upper protection plate using a press machine to thereby cut said stone to be cut. A stone cutting device for cutting stone used as a tile that is used for a pavement or a floor comprising a press portion (14a), a pump unit (31) and an electric control panel (36), wherein cutting plates (29a, 29b) on which the completely same elongate cutting protrusions (30a, 30b) are formed, respectively, are releasably mounted on upper and lower protection plates (18, 20), respectively. With said stone material cutting method and device it is possible to cut stone.
