Abstract
This relates to a heat sealer for engaging heat sealable material between a pair of heat sealer members and clamping the material to be heat sealed under a controlled force. The heat sealing mechanism includes a pair of parallel members which are mounted for movement in unison and in opposite direction and which carry the heat sealing members which face in opposed relation. A pressure device is attached to one of the parallel members for moving the parallel members to a closed heat sealing position and a mechanical mechanism in the form of a cam is connected to the other of the parallel members for overriding the pressure device and effecting opening of the heat sealing members. The pressure device is in the form of a simple fluid cylinder and the fluid supply therefor is of the variable type whereby the controlled force exerted by the heat sealing members on the article to be heat sealed may be selectively varied.
