Abstract

A device for cutting a mat or panel made of mineral wool or a board or panel made of porous construction material, including a system for moving the mat or panel made of mineral wool or the board or panel made of porous construction material, which includes at least one conveyor, capable of moving along a direction, an endless diamond element designed to cut the mat or panel made of mineral wool or the board or panel made of porous construction material, a device for running the endless diamond element in a direction perpendicular to the direction of movement of the mat or panel made of mineral wool or the board or panel made of porous construction material, the endless diamond element being an endless diamond wire, an endless diamond cable or an endless diamond strip.

Dependent claims

A device for cutting a mat or panel made of mineral wool or a board or a panel made of porous construction material, comprising:

a system configured to move the mat or panel made of mineral wool or the board or the panel made of porous construction material, which comprises at least one conveyor adapted to move along a direction,
an element, that forms an endless loop provided with abrasive grains, designed to cut the mat or panel made of mineral wool or the board or the panel made of porous construction material,
a device configured to run the element that forms an endless loop provided with abrasive grains in a direction perpendicular to the direction of movement of the mat or panel made of mineral wool or the board or the panel made of porous construction material, the element that forms an endless loop provided with abrasive grains being a wire that forms an endless loop provided with abrasive grains, a cable that forms an endless loop provided with abrasive grains or a strip that forms an endless loop provided with abrasive grains,
wherein:
the wire that forms an endless loop provided with abrasive grains is a steel wire with a diameter of between 0.80 and 1.30 mm welded to the surface of which are abrasive grains having a mean diameter of between 160 and 200 μm, or
the cable that forms an endless loop provided with abrasive grains is a twisted multistrand steel cable with a diameter of between 0.80 and 1.30 mm welded to the surface of which are abrasive grains having a mean diameter of between 160 and 200 μm, or
the strip that forms an endless loop provided with abrasive grains is a steel strip with a width of between 34 and 42 mm and with a thickness of between 0.4 and 0.8 mm, comprising abrasive grains having a mean diameter of between 160 and 200 μm welded to an edge of the strip having a width of between 2 and 5 mm.

A method for cutting a mat or panel made of mineral wool or a board or a panel made of porous construction material, comprising:

providing a mat or panel made of mineral wool or a board or a panel made of porous construction material,
moving the mat or panel made of mineral wool or a board or a panel made of porous construction material in a direction by a system configured to move the mat or panel made of mineral wool or the board or the panel made of porous construction material, which comprise at least one conveyor,
cutting the mat or panel made of mineral wool or the board or the panel made of porous construction material with an element that forms an endless loop provided with abrasive grains capable of running in a direction perpendicular to the direction of movement of the mat or panel made of mineral wool or the board or the panel made of porous construction material, the element that forms an endless loop provided with abrasive grains being a wire that forms an endless loop provided with abrasive grains, a cable that forms an endless loop provided with abrasive grains or a strip that forms an endless loop provided with abrasive grains,
wherein the cutting is carried out by:
a wire that forms an endless loop provided with abrasive grains consisting of a steel wire with a diameter of between 0.80 and 1.30 mm welded to the surface of which are abrasive grains having a mean diameter of between 160 and 200 μm, or
a cable that forms an endless loop provided with abrasive grains consisting of a twisted multistrand steel cable with a diameter of between 0.80 and 1.30 mm welded to the surface of which are abrasive grains having a mean diameter of between 160 and 200 μm, or
a strip that forms an endless loop provided with abrasive grains consisting of a steel strip with a width of between 34 and 42 mm and with a thickness of between 0.4 and 0.8 mm comprising abrasive grains having a mean diameter of between 160 and 200 μm welded to an edge of the strip having a width of between 2 and 5 mm.
