ABSTRACT:
A sealer is disclosed for sealing upper and lower portions of a web without sealing the portions together, such as side gussets in side gusseted bags. A sealing bar is placed below the web and fixed with respect to the machine. Another sealing bar is placed above the web, parallel to the first one. An air cylinder can urge the upper sealing bar down against the lower one to seal the web. A platen is placed within the side gusset to prevent the portions from being sealed to each other, and the platen floats vertically to accommodate the motion of the sealing bars.
