1 Maintaining single link chain bags against skewing US823640 1986-01-29 US4694959A 1987-09-22 Steven Ausnit; Per Bentsen
Bags in a series have first and second end portions with the bags being separated from one another except for links that connect the first end portions of the bags into a continuous chain, which is wound upon itself on a storage reel. Such winding may be in a vertical spiral fashion, or it may be by engagement by a separable continuous strip, such as a ribbon tape across the second end portions of the bags as reeled upon a core, thereby maintaining the bags in the chain substantially free from skewing relative to one another. Method and apparatus for effecting the reeling of the bag chain are also disclosed.
2 Apparatus for producing transverse weld seams in a two-ply web of plastic film US583541 1975-06-04 US3996093A 1976-12-07 Aloys Winnemoller
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.
