VORRICHTUNG ZUM BEARBEITEN UND ABTRENNEN VON ABSCHNITTEN VON INTERMITTIEREND GEFOERDERTEN BAHNEN

摘要

In an apparatus for applying handles to an intermittently fed web of plastics sheet material and severing bag sections therefrom by transverse weld seams, treating means for the web disposed upstream of two successive pairs of feed rollers and operative when the web is stationary simultaneously carry out like processes on a plurality of web sections which will later be severed into a corresponding number of bags. The feed roller pair nearest to the treating means is effective to feed the web in steps equal to the sum of the lengths of simultaneously treated web sections whereas the other pair feeds the web in steps equal to only one web section length but is operative as many times more frequently as there are simultaneously treated web sections.
