Abstract
A method and apparatus are provided for packaging products between first and second plastic components sealed by using a hot melt adhesive applied by a dispensing applicator in one of several serially arranged stations of a packaging operation. The first plastic component is supported for indexing movement on a transport and moved under a hot melt applicator which is continuously driven in a predetermined path of travel which traverses the entire periphery of the product-loaded first plastic component. The first plastic component is stopped under the applicator for a predetermined dwell time during which the applicator dispenses the hot melt adhesive, then advanced to a position where the second plastic component is applied to form a filled package which is the evacuated and sealed. Apparatus is provided for preventing dripping or stringing of the hot melt adhesives.
