ABSTRACT:
A forming jaw for producing a succession of sealed packages from a tube of sheet packaging material filled with a pourable food product and fed in a direction parallel to its longitudinal axis is disclosed. The jaw includes sealing structure that seals a cross section of the tube; and forming structure that imparts a predetermined shape to the tube between two successive sealed cross sections. The forming structure has first and second surfaces for interacting with the tube and which extend respectively in a direction crosswise to, and in a direction parallel to, the axis of the tube. The first surface has a convex portion which exerts pressure on, to control filling of, the packages being formed.
