ABSTRACT OF THE DISCLOSURE A pre-forming technique for web material utilized to make flexible pouches for fluent products comestibles and non-comestibles in form-and fill equipment of well known type characterized by the initial stretching displacement of each web from its normal plane and in a configuration corresponding to the ultimate spout configuration prior to forming of the pouch with the spout therein, thereby preventing undesired blockage of the spout by unintended adherence of the packaging film in the spout zone during sealing operations. The technique is especially desirable in pouches having a unique and complex reversely curved discharge passageway.
