Patent ID: 8328974

Claim:
A film sticking method for sticking a film to a honeycomb structure using the film sticking apparatus, comprising: a gripping member gripping a film having an adhesive face to hold the film in a planar state; a pressing member pressing said adhesive face of said film being held in a planar state against one end face of a cylindrical honeycomb structure having a plurality of cells formed that communicate between two end faces thereof, and thus sticking said film to said one end face; and a folding member having an opening portion formed that allows an end of said honeycomb structure on the side to which said film is stuck to be inserted, a hardness of the folding member having 10 degrees at the lower limit and 60 degrees at the upper limit, wherein said folding member folds a protruding portion of said film protruding from said one end face of said honeycomb structure by inserting said honeycomb structure into said opening portion, toward a side face of said honeycomb structure, and simultaneously presses at least a part of said folded protruding portion against a part of the side face of said honeycomb structure to stick said film to said side face; the method comprising the steps of: gripping a film to hold the film in a planar state with said gripping member; positioning said honeycomb structure so that said adhesive face of said film being held in a planar state may face said one end face of said honeycomb structure; sticking said film to said one end face by pressing said adhesive face of said film against said one end face of said honeycomb structure with said pressing member; and folding a protruding portion of said film toward a side face of said honeycomb structure by inserting said honeycomb structure into said opening portion of said folding member, and simultaneously pressing at least a part of said folded protruding portion against a part of said side face of said honeycomb structure.
