A masonry veneer machine is disclosed having adjustable fingers for applying the proper amount of pressure to the brick against a guide. The adjustable fingers are disposed on the lateral side of the saw blade, whereas, the guide is disposed on an arbor side of the saw blade. This provides for quick adjustments to the fingers and guide when changing over from cutting bricks of a first size to bricks of a second size which are significantly different from each other.

An apparatus for cutting slabs made of porcelain or like materials includes a support and blocking plane of at least a slab, and at least a cutting group of the slab, arranged superiorly thereof. The cutting group includes rotary tools associated with a carriage mobile along a parallel direction to the support plane; a component for moving the rotary tools independently of one another, in a perpendicular direction to the parallel direction, between two end positions, respectively an active neared position for working on the slab and a non-active distanced position, raised from the slab.

A rare earth magnet block is cutoff machined into pieces by rotating cutoff abrasive blades. Improvements are made by setting the blades on one side of the magnet block, rotating the blades, starting machining operation to form cutting grooves in the magnet block from one side, interrupting the machining operation, moving the blades to the other side of the magnet block, and restarting the machining operation to form cutting grooves in the magnet block from the other side, until the cutting grooves formed from the one and other sides merge with each other.

Cutting bricks includes rotating a turntable having jigs. Bearings on clamp arms of the jigs are urged against a cam surface at first and second sides of the turntable to open the clamp arms to permit loading and unloading of unclamped brick. Bricks are loaded into the jigs on the turntable from both sides of the turntable by positioning the bricks in jigs with opened clamp arms. One clamp arm can clamp the brick against a side plate portion below a saw blade height and one can clamp above saw blade height. The turntable continues to rotate to release the arms from the cam surface to cause clamp arms to close. At least two brick saws positioned adjacent the turntable cut clamped bricks loaded into jigs on the turntable. Cut bricks are unloaded at the sides of the turntable when the clamp arms open.

A product and method to eliminate blade spacers in blade heads or stacks that are formed by multiple blades fixed relative to one another including a plurality of spacerless blades wherein the spacerless blades include a blade core with a blade core thickness that is greater than a segment thickness of grinding and/or cutting segments fixed to the blade core to allow core-to-core contact between adjacent blades in the plurality of spacerless circular blades while also producing segments spacings in the plurality of segments between the adjacent blades without the need for blade spacers.

A preferred embodiment of a hand-operated flush cutting machine includes a front section with a first and a second disc shaped cutter blade which are rotary about an axis of rotation and mounted in the front end of an elongated tool carrier having the substantial shape of a flat bar. The tool carrier is mounted to a rear section of the machine. The rear section is provided with a number of components, including a motor for driving the cutter blades via a power transmission as well as handles and a control for operating the machine. The first, right hand side cutter blade has a first side, which does not face the second cutter blade. The first side defines a first plane which does not intersect any component in the front or rear sections.

The present invention relates to a device (10) and a method for removing contaminated material from a wall, the device (10) comprising suction plates (26) which fix a support system (13) of the device (10) to the wall by means of negative pressure, and a first rotating tool (14) that has impact cutters (16) in the circumferential direction. Disc-shaped saw blades (20) are provided in a second rotating tool (18) mounted upstream of the first rotating tool (14) in the working direction.

A brick cleaning system has: a frame; a first saw comprising a first motor and a first saw blade driven by the first motor, the first saw being connected to the frame; a second saw comprising a second motor and a second saw blade driven by the first motor, the second saw being connected to the frame; and a brick cart connected to the frame. The brick cart is configured to hold a brick. The brick cart selectively translates relative to the frame for feeding the brick in a space between the first and second saw blades such that the first and second saw blades remove mortar from opposite sides of the brick. A method for cleaning used bricks is also disclosed.

A spacer, blade core, assembly and methods for blade and blade core assemblies, including gang blade heads, include openings in blade cores for receiving spacers. A spacer and its opening can be the same shape or different shapes, and spacers can be interconnected or disconnected from each other. A spacer can be in contact or engaged with two blades, three blades, or more.

A cutting apparatus for cutting corner pieces formed of stone or other materials for use as building faces or for cutting flat pieces is disclosed herein. The cutting apparatus includes a frame with a first and a second conveyor operatively attached to the frame. The first and the second conveyors are configured to carry a workpiece from a first end of the frame to the second end of the frame. The first conveyor is disposed at an angle of about 45 degrees to a ground surface supporting the cutting apparatus. The second conveyor is disposed at an angle of about 45 degrees to the ground surface supporting the cutting apparatus, wherein the second conveyor is positioned perpendicularly to the first conveyor so as to form a V-shaped channel therewith. The cutting apparatus further includes a first cutting blade operatively attached to the frame and positioned generally parallel to the first conveyor and a second cutting blade operatively attached to the frame and positioned generally parallel to the second conveyor.
