摘要

Procedure and vertical machine to transform pre containers and flexible containers of the English fold type, stable bottom and pad. The method of the invention consists in manufacturing or/and transforming flexible containers into vertical filling and sealing machines that manufacture or manufacture English fold type, stable bottom or pad type containers, by generating and sealing flaps up or/and down. of the lateral sides of the previous pre-package (6a) or subsequent pre-package (6b) arranged in the vertical machine. Impact bodies (2; 3) installed in the vertical machine are used that, when operated, hit, push and fold at least part of at least one side or side face on at least another part of another side or contiguous face, thus generating at least any one of the plus flaps (11; 12; 13; 14), triangular body flaps (22) or/and manipulated triangular body flaps such as, for example, the flap folded on itself (15) or the flap pulls (2. 3). Subsequently, the flaps are sealed, by means of a sealing mode such as that of a resistance, in order to keep the generated flap permanently stable. Another object of the invention are the different devices to be installed in the machines of the invention or, equally, the vertical or horizontal filling and sealing machines for flexible containers already existing on the current market. These devices have the function of shaping and predisposing the pre-package (6a; 6b) so that afterwards the flaps are optimally generated in the pre-package; the most significant devices (19; 20; 21) are: a) the rammer body (19), intended to widen and stretch the wrapper or sheet from the bottom or/and the lower support face of the pre-package (6a), or b) pressing platform or drawer (20), intended to push and crush the upper part of the pre-container (6b) against the underside of the clamp (1a), causing it to widen three-dimensionally in a cubic shape. The invention also protects different models of packaging, such as mixed packages; one half of pad type and another half of English fold type.
