More Information
Summary:An apparatus for heat sealing composite lids, made of a laminate of a light ductile alloy coated with a layer of thermoweldable plastic material, on glass containers. The apparatus applies, under pressure, a flexible membrane onto said lid while disposed in position on the mouth of a glass container. The membrane is a simple sheet stretchingly supported by its outer periphery on a movably and hingedly supporting frame. The side of said membrane opposite said lid is subjected to a controlled heat flow, thus sealing the lid to the container.
