Abstract

The leading end of an intermittently fed flattened tubular web is clamped by a gripper, whereupon a severing mechanism cuts a section from the web. The gripper advances the leading end of the tube section before the trailing end has cleared a pair of clamping rollers and while a folding roller engages an intermediate portion of the section and moves it laterally to form a loop in the tube section before the latter is discharged transversely.
