Heat sealing system

A heat sealing system comprising:

• a sealer assembly including a pair of heat sealing bars configured to generate heat seals;
• a positioning assembly including a platform and a motor, wherein the sealer assembly is mounted to the positioning assembly, and the motor is configured to move the sealer assembly towards and away from an edge of a table;
• an inlet assembly disposed adjacent said sealer assembly directing an envelope material into said sealer assembly;
• a first pair of rollers and a second pair of rollers included in said inlet assembly, wherein each roller of the first and second pairs of rollers is vertically aligned along a common plane for each pair of rollers and configured to rotate and provide tension to said envelope material entering the sealer assembly, and wherein at least one roller in each of the first and second pairs of rollers being motor driven to control movement of the envelope material into the sealer assembly;
• and,
• wherein said first pair of rollers is laterally spaced from said second paid of rollers along a common plane, and wherein at least one of said first and second pairs of rollers is movably long said common plane towards and away from the sealer assembly to change an angle of the envelope material entering the sealer assembly.
