Embodiment Construction

[0033] figure 1 Shows a wheel arrangement 1 for supporting, driving and transmitting cutting motion to a diamond coil 2 according to a first embodiment of the invention, figure 1Also shown is a wheel 3 around which an endless belt 4 is wound, the surface of which has a plurality of grooves 5 for accommodating the diamond wire 2 of each turn of the diamond wire; The diamond wires 2 are positioned at the desired pitch. The electric motor 6 produces a rotational motion, which, by means of a transmission 7, is transmitted to the wheel 3 and then to the endless belt 4, which transmits the cutting motion to the diamond wire due to its winding on the wheel 3. The wheel 8 or tensioner used to tighten the endless belt is at a distance from the wheel 3 to tension the endless belt 4, shifting the axis of rotation relative to the axis of rotation of the wheel. In order to maintain the lateral position, the endless belt 4 has on its inner surface a profile 9 longitudinal to the direction...

Abstract

A device for the support and / or drive of diamond wire (2) of machines for cutting natural or agglomerate stones, comprising: at least one pulley, wheel or drum for support and / or drive, provided with at least one groove for holding at least one diamond wire (2) for cutting; soft material placed between the diamond wire and the winding groove of the said wire; wherein the soft material (4; 16; 22)is wrapped around the pulley, wheel or drum (3; 18; 25) but not fixed and is interposed in the winding of the diamond wire on it, along the winding arch, and is closed in a ring, similarly to a belt,with the winding of the said ring or belt also on a tightening wheel (8; 19; 30); furthermore, this tightening is achieved by using adjustment means (29; 35) for the tightening wheel to increase the wheelbase of the pulley, wheel or drum (3; 18) for the support and / or drive of the diamond wire in question.

Description

technical field [0001] The present invention relates to a device for supporting, driving and / or transmitting motion to a diamond wire on a machine for cutting natural or agglomerated stone, or to a device for supporting or also transmitting cutting motion to a diamond wire on a machine provided with a diamond coil Line device that cuts stones into sheets of predetermined thickness equal to the size of the starting stone. Various embodiments of a single diamond wire or combinations of multiple diamond wires are included. Background technique [0002] The prior art on machines with diamond coils involves the transmission of motion initiated by motorized pulleys or rollers provided with grooves coated with soft material for receiving individual diamond wires. Also, return pulleys and rollers require grooves coated with said soft material to reduce contact wear and tear between the diamond wire and the grooves of the pulleys or rollers. [0003] Diamond wire consists of severa...
