ABSTRACT:
A machine for the production of weldable plastic film bags from a strip reel, and for the filling of the said bags, comprises means of supporting and unwinding a first strip reel (B.sub.1); means of supporting a second reserve strip reel (B.sub.2); and means (41, 49) of cutting and welding the strip (N), to automatically make the join between the trailing end of the strip being unwound from the first reel (B.sub.1) and the leading end of the strip on the second reel (B.sub.2) when the first reel is about to be used up. In order to bring the strip on reel (B.sub.1) into phase with the strip on reel (B.sub.2), there are provided means (5, 7, 9) of delimiting a predetermined length of the path of the strip between the means of forming, filling and sealing the bags and the means (41, 49) of cutting and welding the strip; a first reference (151) down-line from the means of welding and cutting the strip; and a second reference (153) for the strip from the second reel.
