A method and apparatus for making bags from a film that follows a film path through a bag machine includes an input section located on the film path, a sealing section located on the film path down stream of the input section, an output section located on the film path downstream of the sealing section, and a controller, connected to control the sealing section. The sealing section includes a sealer that includes a heater block and a manifold. There is an air flow path from the heater block to the manifold. Air is heated in the heater block in response to a control signal provided by the controller to the heater block. The heated air is provided through the air path to the manifold. A temperature sensor is disposed in at least one of the air path and the manifold.
A bag machine for forming bags from a film that follows a film path through the machine, comprising:
A method of forming bags from a film that follows a film path, comprising:
The method of claim 23, wherein directing the heated air to a manifold includes providing substantially the same air flow to a middle portion and at least one end portion of the manifold.
