Los documentos citados D01-D04 describen dispositivos de tensado de los hilos de corte de un máquina multifilar para cortar losas a partir de bloques de material pétreo con la ayuda de elementos de soporte, que se deslizan a la lo largo de una dirección, tensionando el hilo de corte. En el documento D01 el dispositivo para el tensionado de los hilos de corte (12), presenta un elemento soporte (8) que incluye al menos un asiento anular para un hilo de corte (12), medios de accionamiento sobre el elemento soporte (8) que permiten su deslizamiento en la dirección (P), tensionando el hilo de corte (12), que incluyen un par de cilindros neumáticos (16) conectados funcionalmente con dicho el elemento de soporte (8) a través de un elemento de conexión (10). El elemento de conexión (10) también se encuentra conectado funcionalmente con el elemento de soporte (8) (ver figuras 1 y 9 y resumen). En el documento D02 el dispositivo (13) para el tensionado de los hilos de corte (11), comprende un elemento soporte (22) que incluye al menos un asiento anular para un hilo de corte (11), medios de accionamiento (32,33) sobre el elemento soporte (22) que permiten su deslizamiento en un dirección predeterminada, tensionando el hilo de corte (11), que incluyen un par de cilindros hidráulicos (32,33) conectados funcionalmente con el elemento de soporte (22) a través de un elemento de conexión (23,26). El elemento de conexión (23,26) también se encuentra conectado funcionalmente con el elemento de soporte (22) (ver figuras 5-11). The documents cited D01-D04 describe tensioning devices of the cutting threads of a multifilar machine for cutting slabs from blocks of stone material with the help of support elements, which slide along one direction, tensioning the cutting thread In document D01 the device for tensioning the cutting wires (12), has a support element (8) that includes at least one annular seat for a cutting thread (12), actuation means on the support element (8 ) which allow its sliding in the direction (P), by tensioning the cutting wire (12), which include a pair of pneumatic cylinders (16) functionally connected with said support element (8) through a connecting element ( 10). The connection element (10) is also functionally connected to the support element (8) (see figures 1 and 9 and summary). In document D02 the device (13) for tensioning the cutting wires (11), comprises a support element (22) that includes at least one annular seat for a cutting wire (11), drive means (32, 33) on the support element (22) allowing its sliding in a predetermined direction, by tensioning the cutting wire (11), which include a pair of hydraulic cylinders (32,33) functionally connected with the support element (22) a through a connection element (23,26). The connection element (23,26) is also functionally connected with the support element (22) (see figures 5-11). En el resto de documentos los medios de accionamiento sobre el elemento soporte presentan un único cilindro, hidráulico, neumático o eléctrico. Los documentos D05-D06 hacen referencia a los medios que permiten detectar una variación del flujo de aire en el interior del circuito neumático, detectando la rotura de uno o más hilos. In the rest of the documents, the actuation means on the support element have a single cylinder, hydraulic, pneumatic or electric. Documents D05-D06 refer to the means that allow a variation of the air flow inside the pneumatic circuit to be detected, detecting the breakage of one or more wires. En ninguno de los documentos citados D01-D06 se describe un elemento de conexión como el reivindicado, en el que las zonas de conexión del elemento de conexión con los vástagos de los cilindros de accionamiento del elemento soporte están colocadas en una segunda porción de borde, en los lados opuestos respecto a un plano medio interpuesto entre dichas zonas de conexión y sustancialmente ortogonal al plano definido por dicho el asiento anular. None of the documents cited D01-D06 describes a connection element as claimed, in which the connection areas of the connection element with the rods of the drive cylinders of the support element are placed in a second edge portion, on the opposite sides with respect to a middle plane interposed between said connection zones and substantially orthogonal to the plane defined by said annular seat. Por lo tanto, ninguno de los documentos citados en el Informe sobre el Estado de la Técnica, tomados solos o en combinación, revelan las características técnicas definidas en la reivindicación independiente 1. Además, no se considera obvio que un experto en la materia obtenga la invención a partir de los documentos mencionados anteriormente. Therefore, none of the documents cited in the State of the Art Report, taken alone or in combination, reveal the technical characteristics defined in the independent claim 1. Furthermore, it is not considered obvious that a person skilled in the art obtains the invention from the documents mentioned above. OPINIÓN ESCRITA  WRITTEN OPINION En consecuencia, se considera que la reivindicación 1 cumple los requisitos de novedad, actividad inventiva y aplicación industrial (artículos 6.1, 8.1 y 9 de la Ley 11/1986 de patentes). Consequently, claim 1 is considered to meet the requirements of novelty, inventive activity and industrial application (articles 6.1, 8.1 and 9 of Patent Law 11/1986). Respecto a las reivindicaciones 2 a 8, éstas son dependientes de la reivindicación 1 y, por lo tanto, cumplen igualmente los requisitos de la Ley 11/86 con respecto a la novedad, actividad inventiva y aplicación industrial (artículos 6.1, 8.1 y 9 de la Ley 11/1986 de patentes). With respect to claims 2 to 8, these are dependent on claim 1 and, therefore, also meet the requirements of Law 11/86 with respect to novelty, inventive activity and industrial application (Articles 6.1, 8.1 and 9 of Patent Law 11/1986). Las reivindicaciones 9 y 10 referentes a la máquina multifilar, teniendo en cuenta la argumentación anterior, cumplen también los requisitos de la Ley 11/86 con respecto a la novedad, actividad inventiva y aplicación industrial (artículos 6.1, 8.1 y 9 de la Ley 11/1986 de patentes). Claims 9 and 10 concerning the multifilar machine, taking into account the previous argument, also meet the requirements of Law 11/86 with respect to novelty, inventive activity and industrial application (Articles 6.1, 8.1 and 9 of Law 11 / 1986 patent).
