The film sticking apparatus includes: a gripping member; a pressing member pressing the adhesive face of the film being held in a planar state against one end face of a cylindrical honeycomb structure having a plurality of cells, and thus sticking the film to the one end face; and a folding member having an opening portion formed that allows an end of the honeycomb structure on the side to which the film is stuck to be inserted, wherein the folding member folds a protruding portion of the film protruding from the one end face of the honeycomb structure by inserting the honeycomb structure into the opening portion, toward a side face of the honeycomb structure, and simultaneously presses at least a part of the folded protruding portion against a part of the side face of the honeycomb structure to stick the film to the side face.

1. 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; anda 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, whereinsaid 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; andfolding 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. 2. The film sticking method according to claim 1, wherein an open edge of said opening portion and an outer peripheral edge of the end face of said honeycomb structure are in the same shape or in a similar shape with each other, and the ratio of the diameter of said open edge to the outer diameter of the end face of said honeycomb structure is 80% at the lower limit and 105% at the upper limit. 3. The film sticking method according to claim 1, wherein, when said honeycomb structure is inserted into said opening portion of said folding member, said honeycomb structure is positioned, relative to said folding member, so that the whole area of outer peripheral edge of said end face may contact with the face of said folding member on the side into which said honeycomb structure is inserted. 4. The film sticking method according to claim 2, wherein, when said honeycomb structure is inserted into said opening portion of said folding member, said honeycomb structure is positioned, relative to said folding member, so that the whole area of outer peripheral edge of said end face may contact with the face of said folding member on the side into which said honeycomb structure is inserted. 5. The film sticking method according to claim 1, wherein said pressing member is in a cylindrical shape rotatable around the central axis in the longitudinal direction thereof, and is positioned so that said central axis in the longitudinal direction may become orthogonal to the central axis in the longitudinal direction of said honeycomb structure, and wherein said pressing member travels in parallel with said end face at a speed ranging from 30 to 800 mm/sec while rotating, thus pressing said film against said end face with the outer peripheral face of said pressing member. 6. The film sticking method according to claim 2, wherein said pressing member is in a cylindrical shape rotatable around the central axis in the longitudinal direction thereof, and is positioned so that said central axis in the longitudinal direction may become orthogonal to the central axis in the longitudinal direction of said honeycomb structure, and wherein said pressing member travels in parallel with said end face at a speed ranging from 30 to 800 mm/sec while rotating, thus pressing said film against said end face with the outer peripheral face of said pressing member. 7. The film sticking method according to claim 3, wherein said pressing member is in a cylindrical shape rotatable around the central axis in the longitudinal direction thereof, and is positioned so that said central axis in the longitudinal direction may become orthogonal to the central axis in the longitudinal direction of said honeycomb structure, and wherein said pressing member travels in parallel with said end face at a speed ranging from 30 to 800 mm/sec while rotating, thus pressing said film against said end face with the outer peripheral face of said pressing member. 8. The film sticking method according to claim 4, wherein said pressing member is in a cylindrical shape rotatable around the central axis in the longitudinal direction thereof, and is positioned so that said central axis in the longitudinal direction may become orthogonal to the central axis in the longitudinal direction of said honeycomb structure, and wherein said pressing member travels in parallel with said end face at a speed ranging from 30 to 800 mm/sec while rotating, thus pressing said film against said end face with the outer peripheral face of said pressing member.
