Patent ID: 7021028

Claim:
A process for the production of portion packs of viscous to pasty filling material in a tubular film, the process comprising the steps of: a) filling a previously formed portion of tubular film having a previously closed first end with a filling material introduced under pressure by filling means at a filling station; b) drawing a film strip portion, having a pair of longitudinal ends, off a supply toward a welding station and bending the film strip portion into a tubular form, wherein the step of drawing the film strip portion off the supply is accomplished only by the pressurized filling of the tubular film which is attached to the film strip; c) stopping the pressurized filling of the tubular film by stopping the filling means when a predetermined amount of filling material has been introduced into the tubular film; d) forming a portion pack of a predetermined length by closing the tubular film with a braid formation at a predetermined distance from the first closed end of the tubular film while the pressurized filling is stopped; e) welding or sealing the longitudinal ends of the film strip portion to form an additional portion of tubular film while the pressurized filling is stopped, wherein the step of welding and sealing the longitudinal ends of the film strip portion is accomplished over a film strip length corresponding at least to the portion pack length.
