A vertical form fill and seal (VFFS) machine is configured to place a fitment, such as a spout (102), on the longitudinal fin seal (104) of a container (200, Fig. 4). The fitment (102) dispatched from a vibratory bowl (22) via an adjustable track (24). The fitment is then secured to edges of the film (100) by longitudinal sealing bars (26) and the edges of the film are likewise secured to each other by the longitudinal sealing bars (26) thereby forming a longitudinal fin seal (104). Depressions are machined in the machine direction center of the sealing bars (26) in order to accommodate the shape of the fitment (102). The film is drawn over an oversized collar (18) and an undersized tube (12) and bars (40, 42, Fig. 3) so as to create excess film in order to form gussets providing a stand-alone capability. <IMAGE> |
