A method to produce a stand-up pouch (S) provides to make available at least one pre-shaped pouch (PS) initially having a flat configuration, which is defined by a lateral wall (111), by a bottom wall (112) and is provided with at least one hole (113), the pre-shaped pouch (PS) being accessible in correspondence with an aperture (114) opposite the bottom wall (112), the pre-shaped pouch (PS) being positioned so that the hole (113) is aligned with respect to an axis of insertion (Z). The method then provides to manipulate the pre-shaped pouch (PS) by means of holding and shaping means (15, 16) so as to shape the pre-shaped pouch (PS) so as to make available a containing chamber (V) thereof, and to move an insertion rod (13) along the axis of insertion (Z), through the aperture (114), inside the containing chamber (V) just defined, in order to position, and temporarily hold in position, a delivery mean (117) in correspondence with the hole (113).
Method to produce a stand-up pouch (S) equipped with a delivery mean (117) configured to allow the delivery of substances or products intended to be contained in the pouch (S), said method providing to:
Method as in any claim hereinbefore, characterized in that during the insertion movement of said insertion rod (13) inside the pre-shaped pouch (PS) through said aperture (114), said insertion rod (13) reaches an end-of-travel position in correspondence with which it thrusts at least against the bottom wall (112) determining an at least partial stretching of said bottom wall (112).
Method as in any claim hereinbefore, characterized in that it provides to move heated sealing means (18) along said axis of insertion (Z) in a direction opposite the direction of insertion of said insertion rod (13) so as to abut against said insertion rod (13), which is keeping said delivery mean (117) in position, so as to heat part of said bottom wall (112) and said delivery mean (117) making it integral with said bottom wall (112).
Method as in any claim hereinbefore, characterized in that the holding and shaping means comprise first and second holding and shaping means (15, 16) which hold the pre-shaped pouch (PS) in two directions incident with each other, respectively in a first shaping direction (X) and in a second shaping direction (Y).
Method as in any claim hereinbefore, characterized in that the bottom wall (112) of the pre-shaped pouch (PS) is flat or substantially flat when said pre-shaped pouch (PS) is made available in the shaping station (11).
Method as in any claim hereinbefore, characterized in that it is carried out in a machine separate from the machine in which the pre-shaped pouch (PS) was produced.
Machine for producing a stand-up pouch (S) able to carry out the method as in any claim hereinbefore, said machine comprising at least one shaping station (11) provided at least with:
