The packaging machine has at least a pair of molding components (35) that can be circulated and continuously moved and can securely clamp and seal the sections at equal intervals of the sheet material tubes (3); the filling tubes (50) are at least partially packed The material tube (3) extends inside to convey the food into the tube; and a rigid damping member (52) which also extends in the packaging material tube (3) and is fixed to and surrounds at least a part (51) of the filling tube (50), An air chamber (54) is formed together with the filling tube to control the vertical flow of food in the packaging material tube (3) during operation of each molding assembly (35); the damping member (32) and the filling tube (50) extend as much as possible, but Do not interfere with the molding assembly (35). Slaves 1. A packaging machine (1) for producing a sealed package (2) of a flowable food product using a sheet-like packaging material tube (3) conveyed along a vertical path (A), the packaging machine (1) comprising: A pair of molding assemblies (35) are cyclically and continuously movable and can securely clamp and seal the sections of the sheet material tubes (3) at equal intervals, forming opposite ones of the formed packages (2). Sealing strips (44); said forming elements (35) include first and second jaws (13, 14), respectively, moving along first and second circulation paths (P, Q), respectively, said path being vertical Both sides of the path (A) extend to form working portions (P1, P2, Q1, Q2) each adjacent to the vertical path (A) along the working portion of the sealing strip (44) in the tube of packaging material (3) The upper forming; and the filling mechanism (5), including the filling tube (50), extends at least partially within the packaging material tube (3) to convey the food into the tube; and a rigid damping member (52), which also The packaging material tube (3) extends and is fixed to and surrounds at least a portion (51) of the filling tube (50), and together with the filling tube forms an air chamber (54), which hinders the formation of the sealing strip. The vertical flow of food in the material pipe (3) is characterized in that at least the filling pipe (50) has a food outlet (57) located along the vertical path (A) at a certain distance from the first holding height. The distance does not exceed 45% of the distance (D1) between the first grip height and the maximum height of the first and second paths (P, Q).
