ABSTRACT:
In an apparatus for producing transverse weld seams in a continuously fed two-ply web of plastics film and comprising a rotary welding cylinder about which the web is partially slung and which is provided with a plurality of welding bars at its periphery, the welding bars are steplessly adjustable radially of the cylinder, the smallest spacing between adjacent said transverse weld seams corresponds to twice the spacing between adjacent welding bars when the latter are in their retracted position, steplessly radially adjustable supporting members for the web are provided between the welding bars, and the welding bars are energizable by a sequence control in a sequence which is independent of the number of said welding bars.
