Abstract

A form and fill machine for resealable plastics bags having reclosable fastening strip adjacent the mouth thereof, the machine comprising a filling tube (60) around which the bags are formed on a continuous tube from sheet material upon which the fastening strip is attached, means (66, 68) for advancing the continuous tube over the filling tube in bag-width steps, sealing means (76) for forming side seams and at least partially severing successive bags at bag width intervals, and means (78, 80) for spreading the lower end of the continuous tube prior to forming a side seam, characterized in that the spreading means comprises at least one means (80) for externally engaging a portion of the continuous tube so as to position the portion of the tube whereat the fastening strip is disposed relative to the sealing means.
