In the factories of transformation of the granite, marble and natural stones, different processes are made from the extraction of the large blocks that serve as raw material. The first process that is normally carried out is the primary sawing of these blocks in sheets of a variable thickness, normally between 2 and 1 O centimeters thick, using in this process, modern diamond multi-wire cutters.
Estas máquinas cortadoras emplean diversos bucles cerrados de hilo diamantado como medios de corte en las labores de serrado primario These cutting machines employ various closed loops of diamond wire as cutting means in primary sawing work

Dichos hilos de corte se suelen montar sobre varias poleas, una de ellas normalmente motorizada y las otras conducidas, formando cada hilo un bucle cerrado con el que se efectúan los diferentes cortes en el bloque de la piedra. En los últimos tiempos los fabricantes de maquinaria han comenzado a desarrollar máquinas que emplean múltiples hilos de corte diamantados, los cuales se montan sobre volantes y tambores de múltiples canales sobre los que se montan los diferentes hilos de corte con el objeto de realizar de forma simultanea los cortes paralelos de los bloques de piedra, obteniéndose por tanto unas producciones muy significativas. or cut the blocks of natural stone. Said cutting threads are usually mounted on several pulleys, one of them normally motorized and the other driven, each wire forming a closed loop with which the different cuts are made in the block of the stone. In recent times, machinery manufacturers have begun to develop machines that use multiple diamond cutting threads, which are mounted on steering wheels and multi-channel drums on which the different cutting threads are mounted in order to perform simultaneously the parallel cuts of the stone blocks, thus obtaining very significant productions.
Las máquinas hasta ahora empleadas, presentan diferentes problemas a la hora de realizar y mantener el correcto tensionamiento individual de los hilos de corte, puesto que el control de este parámetro influye de manera fundamental en el comportamiento y durabilidad de los hilos diamantados. The machines used up to now have different problems when making and maintaining the correct individual tension of the cutting wires, since the control of this parameter fundamentally influences the behavior and durability of the diamond wires.

La acción indirecta e individual del actuador sobre la polea correspondiente; y el montaje de dichas poleas sobre brazos-horquilla independientes, que pivotan sobre rodamientos, permite anular la acción de posibles holguras, fricciones y los rozamientos de los numerosos elementos que intervienen en el dispositivo de tensionado y que puedan afectar de manera determinante en el correcto tensionado y control de cada uno de los hilos, garantizando además robustez y eficacia al dispositivo. The indirect and individual action of the actuator on the corresponding pulley; and the assembly of said pulleys on independent fork-arms, which pivot on bearings, allows to cancel the action of possible clearances, frictions and friction of the numerous elements that intervene in the tensioning device and which can affect the correct way tensioning and control of each of the threads, also guaranteeing robustness and efficiency to the device.
Este dispositivo permite controlar el tensionado de cada uno de los hilos de forma independiente, por una parte, controlando la presión de trabajo de cada uno de los actuadores, y por otra parte, controlando la posición o carrera de estos actuadores mediante un dispositivo de lectura, que nos permite en cada momento controlar los parámetros de cada bucle de hilo. This device allows to control the tensioning of each of the wires independently, on the one hand, by controlling the working pressure of each of the actuators, and on the other hand, by controlling the position or stroke of these actuators by means of a reading device , which allows us to control the parameters of each thread loop at all times.
