Abstract

A process and apparatus for producing bag-like packs including a continuous strand (17) which is formed from packaging material folded in a V-shape and having transverse seams (15). Prepared portions (21) of fibrous filling material are pushed into pockets (18), open at the side, during the continuous transporting of the strand (17) by the apparatus. Thereafter, the pockets (18) are closed at a longitudinal seam (16) formed during the continuous transporting. The packs are formed by being severed from the strand (17). The strand (17) and the portions (21) are transported by synchronously running endless conveyors, and specifically by a spreading ring (27) and a portion turret (35), respectively. The above-mentioned conveyors are mounted axially parallel to each other such that, with synchronous running, the portions (21) are pushed radially out of the portion turret (35) into the pockets (18).
