Abstract

Packaging machine characterized in that it is constituted by a bedplate at the end of which there is a rotating support in which there is a coil of flexible laminar material, including heat shrinkable, such as polypropylene, saran or other suitable, forming said material by two overlapping sheets completely separated, or joined by one of its edges forming a dihedral angle, depending on which, next to the support there is a packaging tray whereby a sheet of the two that constitute the coil, passes above the tray, while the other one does it underneath it in order to achieve sufficient separation between the two sheets to introduce among them the solid items to be packed, having the machine in the base itself and then the packing tray, an articulated rectangular frame, fixed on one of its sides to the bench and then to the packing tray, an articulated rectangular frame, fixed on one side of the bed and with a drive handle, which when lowered onto the welding platform welds, electronically, the free edges of the two overlapping sheets, joining them to each other, while cutting, by the half, the welding, in order to separate the already formed wrapping and leaving together, by self-welding, the edges corresponding to the half of the welding of the immediate container to be made, and also performs, simultaneously to this, the operation of pricking of the container constituted so that the air contained in the same comes out, in the cases in which, after the container has been formed, it must be introduced into a heat chamber by contraction of the envelope that constitutes it.
