ABSTRACT:
Apparatus is provided for sealing heat sealable material with a single actuation drive train. The drive train comprises a series of gripping, heating and squeezing elements directly actuatable and sequentialy staged in conjunction with eccentric linkages and the rotational position of a single drive shaft operable by a single handle and/or input source. In a manual mode the second hand of the operator is thus free to collect and position the material to be sealed, saving time and reducing operator error. The gripping and squeezing elements and their operation are also selectively programmable by the construction and orientation of the particular eccentric linkage to facilitate wide variations in the scope of sealing applications.
