    The corner flap folding device comprises a base support (1) to be fixed to a mold of a laminar material box forming machine, an intermediate shaft (5) rotatably mounted on the base support (1) in a position perpendicular to a base (c1) of a box of sheet material (c) being formed, a pusher shaft (3) which forms an angle with the intermediate shaft (5) and which is connected to the intermediate shaft (5) by a joint cardan (6), a pusher member (2) attached to the pusher shaft (3) and an actuator (4) installed in the base support (1) and which rotates the intermediate shaft (5) by a mechanical transmission and thereby it rotates the pusher member (2) between a retracted position and a tightening position by describing an arc in a plane inclined with respect to the base (c1) of the box (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    The pusher shaft 3 has a pusher member 2 that rotates about the axis E3 of the pusher shaft 3 between a withdrawn position and a clamping position under the action of the actuator 4. In the withdrawn position (Fig. 5) the pusher member 2 is outside the box, and in the tightening position (Fig. 6) the pusher member is inside the box.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.
    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.
    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.
    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 .

    It is being formed in order to adapt the folding device 50 to boxes of laminar material C of different types.
    For this purpose, this fixing device comprises a fixing member 24 connected to a connection attachment 25 fixed to the base support 1 for example by means of one or more screws (not shown) inserted through respective holes 35, 36 (Fig. 4) . The fixing member 24 has an elongated hole 26 perpendicular to the base C1 of the sheet material box C being formed, and through it one or more fixing screws (not shown) through which the fixing element can be installed 24 is fixed to a structural element (not shown) of the mold of the sheet forming machine. The connection appendix 25 has an elongated hole 28 formed parallel to the base C1 and preferably parallel to the slats or the slats of the sheet material box C being formed, and the fixing member 24 has one or more holes 27 facing each other. to the elongated hole 28 of the connection appendix 25, so that one or more fixing screws (not shown) can be installed therethrough.
    Fig. 8 shows a corner flap folding device for sheet forming machine according to another embodiment of the present invention, which is analogous to the embodiment described above in relation to Figs. 1 to 7 except for the mechanical transmission that transmits the movement of the actuator 4 to the intermediate shaft 5.
    In the embodiment shown in Fig. 8, the actuator 4 also comprises a linear actuator, such as a dynamic fluid cylinder 29, articulated connected to the base support 1 by a pivot 31, although alternatively it could be connected to the base support 1 in a fixed position, and provided with an extensible rod 30. However, here a rack 38 is fixed to the end of the stretch rod 30, and the rack 38 is engaged with a pinion 37 fixed to the intermediate shaft 5.
    In the base support 1 or in another element fixed thereto, a guide wheel 39 is installed which rolls along a guide surface 40 formed on one side of the rack 38 opposite the teeth 41 thereof, so that it wheel 39 guides the movements of the rack 38 and prevents its teeth 41 from escaping the pinion 37.
    In another alternative embodiment (not shown) the actuator is a rotary actuator, such as an electric motor or servomotor, fixed to the base support 1 and operatively connected to rotate a spindle that engages with a pinion fixed to the intermediate shaft 5, so that The spindle and pinion constitute the mentioned mechanical transmission.
