El árbol de empujador 3 tiene fijado un miembro empujador 2 que gira respecto al eje E3 del árbol de empujador 3 entre una posición retirada y una posición de apriete bajo la acción del actuador 4. En la posición retirada (Fig. 5) el miembro empujador 2 está fuera de la caja, y en la posición de apriete (Fig. 6) el miembro empujador está dentro de la caja. En virtud del ángulo A de inclinación del eje E3 del árbol de empujador 3, el miembro empujador 2 describe un arco en un plano inclinado respecto a la base C1 de la caja de material laminar C que está siendo formada en el molde de la máquina formadora de cajas de material laminar, y en el trayecto entre la posición retraía y la posición de apriete, el miembro empujador 2 interfiere con la solapa de esquina C7, con la solapa de esquina C6 o ambas a la vez, y empuja, pliega y presiona la solapa de esquina C4 para formar la columna de esquina de la caja de material laminar C. The pusher shaft 3 has a pusher member 2 that rotates about the axis E3 of the pusher shaft 3 between a withdrawn position and a clamping position under the action of the actuator 4. In the withdrawn position (Fig. 5) the pusher member 2 is outside the box, and in the tightening position (Fig. 6) the pusher member is inside the box. By virtue of the inclination angle A of the axis E3 of the pusher shaft 3, the pusher member 2 describes an arc in an inclined plane with respect to the base C1 of the sheet material box C being formed in the mold of the forming machine of boxes of sheet material, and in the path between the retracted position and the tightening position, the pusher member 2 interferes with the corner flap C7, with the corner flap C6 or both at the same time, and pushes, folds and presses the corner flap C4 to form the corner column of the sheet material box C.

En la Fig. 6, el miembro empujador 2 interfiere con la solapa C6, en cuyo caso la solapa C7, la cual ha sido previamente engomada, será presionada adicionalmente contra el testero C2 por unas palas de apriete (no mostradas). Las mencionadas palas de apriete forman parte de un dispositivo de apriete bien conocido en el campo de las máquinas formadoras de cajas de material laminar, el cual no forma parte de la presente invención por lo que su descripción será omitida. In Fig. 6, the pushing member 2 interferes with the flap C6, in which case the flap C7, which has been previously glued, will be pressed further against the tester C2 by tightening blades (not shown). The aforementioned tightening blades are part of a tightening device well known in the field of sheet forming machines, which is not part of the present invention, so its description will be omitted.

No obstante, mediante una regulación apropiada del dispositivo plegador 50, y/o mediante el uso de una junta cardán doble, el miembro empujador 2 puede empujar y plegar inicialmente la solapa de esquina C4 en su conjunto y presionar finalmente la porción de solapa C7 contra el testero C2, en cuyo caso se podría prescindir de las palas de apriete. However, by proper adjustment of the folding device 50, and / or by using a double gimbal joint, the pushing member 2 can initially push and fold the corner flap C4 as a whole and finally press the flap portion C7 against the tester C2, in which case the tightening blades could be dispensed with.

La placa guía 9 tiene un agujero alargado 10 que define un trayectoria curva cuyo centro está alineado con un centro de rótula de dicha junta cardán 6, y el soporte auxiliar 8 tiene un agujero 11 enfrentado a dicha trayectoria curva de dicho agujero alargado 10. el soporte auxiliar 8 se fija a la placa guía 9 mediante un tornillo 12 insertado a través del agujero 11 del soporte auxiliar 8 y del agujero alargado 10 de la placa guía 9, y asegurado mediante una tuerca 13. Esto permite variar la posición angular del soporte auxiliar 8 respecto al soporte base 1 y con ello variar el ángulo A que forma el eje E3 del árbol de empujador 3 con el eje E5 del árbol intermedio 5 con el fin de adaptar el dispositivo plegador 50 a cajas de material laminar C de diferentes tipos. The guide plate 9 is integral with a piece 32 fixed to the base support 1, for example, by one or more screws (not shown) inserted through respective holes 33, 34 (Fig. 4). The guide plate 9 has an elongated hole 10 defining a curved path whose center is aligned with a ball joint center of said cardan joint 6, and the auxiliary support 8 has a hole 11 facing said curved path of said elongated hole 10. the auxiliary support 8 is fixed to the guide plate 9 by means of a screw 12 inserted through the hole 11 of the auxiliary support 8 and the elongated hole 10 of the guide plate 9, and secured by a nut 13. This allows varying the angular position of the support auxiliary 8 with respect to the base support 1 and thereby vary the angle A that forms the axis E3 of the pusher shaft 3 with the axis E5 of the intermediate shaft 5 in order to adapt the folding device 50 to boxes of laminar material C of different types .
