Film-aligning device for air cushion maker

Abstract

A film-aligning device applicable to an air cushion maker implements an eclectic heater to partially heat and soften a plastic film before the plastic film receives an inflating process and a softening process. When the plastic film is tending to proceed slantingly, the heated and soften plastic film performs a plastic deformation to realign the feeding stork of the plastic film.

1 . A film-aligning device applicable to an air cushion maker, which is characterized in having an eclectic heater for partially heating and softening a plastic film before the plastic film receives an inflating process and a softening process. 
     
     
         2 . The film-aligning device as claimed in  claim 1 , wherein the eclectic heater is provided below a plane where the plastic film passes along. 
     
     
         3 . The film-aligning device as claimed in  claim 1 , wherein the eclectic heater heats the plastic film for an entire width of the plastic film. 
     
     
         4 . The film-aligning device as claimed in  claim 1 , wherein the air cushion maker primarily comprises a base and a cover that is liftably affixed to the base, in which a plastic film roll is rotatably mounted on the base so that at least one film-pulling roller set serves to draw the plastic film out from the plastic film roll while the eclectic heater is settled on the base between the plastic film and the film-pulling roller set and right below a plane where the plastic film passes along. 
     
     
         5 . The film-aligning device as claimed in  claim 4 , wherein the heater is parallel to the film-pulling roller set. 
     
     
         6 . The film-aligning device as claimed in  claim 4 , wherein a pressing roller is provided on the cover adjacent to the plastic film roll for contacting the heater.
