Abstract: A method for forming a food product into a circular shape, wherein both ends of an elongated food product are connected each other and closed, or into a C-shape, wherein both ends of the elongated food product face each other and opened. The method includes (a) fixing one end of the elongated food product to a rotatable core member, (b) pressing the food product toward the core member by moving the core member close to and away from a pressing roller, when the food product is formed into a circular shape by being wound around the core member by rotating the core member, and (c) separating the formed food product and the core member by releasing the food product from the core member, after forming the food product 3 into a required shape by being wound around the core member.

Abstract: Removable mask films 303 are formed on the both sides of the substrate having the adhesive layer 302 by applying and drying a resin varnish 304 including a ultraviolet-absorbing agent, and fine through holes 306 are formed by using a third harmonics YAG solid-state laser light with a relatively short wavelength not longer than that in the ultraviolet range in such a way that the effects of such a residual strain as the conventional embodiment forming a removable mask film by a laminating process may be decreased as well as the more fine hole drilling compared with conventional embodiment using the carbon dioxide gas laser with a relatively long wavelength may be performed.
