Abstract:
An improved method for heat-splicing a trailing end of a first plastic material web and a leading end of a second plastic material web where the first and second webs each have a longitudinal axis and each have side edges that are generally parallel with the axis, the method comprising the steps of:(a) providing a trailing end of first plastic material web and a leading end of a second plastic material web so that the ends are adjacent and so that the side edges of the first and second webs are generally axially aligned; and (b) bringing a heated wire into contact with sequential portions of the adjacent ends of the first and second webs, starting with a portion of the web ends adjacent to one side edges of the web ends and continuing transversely across the web ends, to heat seal the adjacent ends of the webs together.
