ABSTRACT:
An axially elongated tube is slideably and pivotally supported within a tlar housing from which the tube extends rearwardly for connection to a source of vacuum. The vacuum is selectively applied through the tube from a flattened forward end thereof to a workpiece after the tube is slideably displaced rearwardly from a retracted to an extended position within the housing. A hand grip on the housing enables it to be manually held in operative relation to the workpiece. A support assembly pivotally mounted on the housing adjustably positions a heating jaw electrically connected by a switch on the housing to a power supply for performance of heat sealing operations on the workpiece.
