摘要：An improved packaging machine that has improved features for feeding a web(11) in the form of a continuous chain of bags through the machine while helping maintain

the web in proper alignment and proper tension, and having additional features forimproved loading of the bags. The improved web feed includes a dancer assemblyequipped with a pair of nips that are driven at speeds responsive to the rate of web travelthrough the machine so that tension between a web supply and the dancer nips isisolated from the downstream portions of the web. A web feed mechanism whichautomatically threads the web through baggers is also provided. The web feedmechanism includes elastic belts (76,77) which frictionally grip the web to isolate thetension in the section between the dancer nips and the belts from the tension of the webfeed mechanism. Nips (73,74) adjacent the load station and at the downstream end of theweb feed mechanism have surface speeds exceeding the surface speed of the belts tomaintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station. Other features includea cantilevered support of the web supply and bagger, a bagger support which functionsas a plenum, an improved dancer assembly, and improved application of compressed airfor bag opening.
