ABSTRACT:
A method and a machine for continuous production of liquid-filled packages employs a series of transverse welding mechanisms for making seams across a hose-like material. Thus, pockets are formed into which liquid material is introduced somewhat in excess of the desired nominal amount. The over-filled pocket is then moved to a squeezing station where pressure is applied to force part of the liquid back out of the pocket into the next following pocket and where the pocket is shaped into the final package. When the desired final shape and volume are reached, the upper seam is completely welded, thus closing the package which is then severed from the hose.
