A method for producing a patterned pressure-sensitive adhesive body includes a pattern forming step of cutting a pressure-sensitive adhesive layer in a pressure-sensitive adhesive film including a first release film and the pressure-sensitive adhesive layer laminated on one surface of the first release film so as to form a first slit in a pattern shape and an outer frame forming step of cutting the first release film and the pressure-sensitive adhesive layer so as to form a second slit in an outer frame shape surrounding the pattern shape. The second slit has a discontinuous portion in a cutting direction.

The invention provides a method of inflation extrusion molding, comprising: introducing one or more resin materials extruded from one or more extruders into a die; subsequently extruding the resin material(s) from the die and inflating the extrudate into a cylindrical shape having a predetermined diameter by blown-film extrusion; and then passing the cylindrical inflated resin material through a space between stabilizers which face each other at a predetermined angle, to deform the cylindrical resin material into a flat tube shape having an elongated elliptic section, thereby producing a film or sheet having a predetermined width, wherein the deformation of the cylindrical inflated resin material into a flat tube shape having an elongated elliptic section is assisted by a guide device to thereby facilitate the deformation.

An adhesive tape inserted into a tape inserting clearance defined between a tape supplying roller and a tape guide is supplied to joining rollers while being wound around the tape supplying roller under guidance. At the tape inserting clearance, one side edge of the adhesive tape is guided to a tape positioner in slide contact, to be positioned in a tape width direction, and further, the adhesive tape T is inserted and moved while allowing the tape to be moved toward the other side edge of the adhesive tape.
