A method and apparatus for bag making includes an input section, a sealing section and an output section. The sealing section includes a seal bar having a heat pipe with a relief zone, through which pressure is relieved. The heat pipe is preferably disposed in or near the seal bar. The relief zone can be a valve that opens and closes, or other reusable devices, or it can be a destructive relief zone. The heat pipe is preferably a generally closed cylindrical shape with the relief zone located on one end. The heat pipe can have a second relief zone, possibly located at the other end of the heat pipe. Fluid may be in the heat pipe. The invention can be implemented as a bag machine with a seal bar, or a seal bar with a heat pipe, or solely as a heat pipe.
A bag making machine, comprising:
A method of making bags, comprising:
A bag making machine, comprising:
A bag making machine, comprising:
A seal bar for a bag making machine, comprising:
A heat pipe, such as that for a bag machine, comprising a pipe, and a relief zone on the pipe, whereby when the pressure in the heat pipe near the relief zone substantially exceeds a desired level, the relief zone vents the pressure.
A method of preventing excess pressure in a heat pipe, such as that for a bag machine, comprising relieving the pressure in the heat pipe through a relief zone when the pressure in the pipe near the relief zone substantially exceeds a desired level.
A heat pipe, such as that for a bag machine, comprising:
