To provide a method for removing a foreign matter which gets rid of a foreign matter adhering to the lip part of a die while leaving a molding device in an operating mode.
This method takes the following procedures: first, the end part 62 of a remover is moved in a direction along one edge 38 of the paired edges in parallel with a lip aperture 32 while holding the end part 62 at a position apart from a lip part 34 by transferring a retainer 42 along a spline shaft 46; next, the end part 62 of the remover is moved to the edge 38 along a lip surface 30 by thrusting a handle 60 of the remover as far as the surface 66 of a position regulating part 64 can come into contact with the surface 68 of the retainer 42. Through the described process, the foreign matter adhering to the lip part 34 near the edge 38 is removed together with a resin by the action to press the foreign matter against the resin squeezed out of the lip aperture 32. Consequently, it is possible to remove the foreign matter adhering to the lip part 34 by this method while the molding device is left in an operating mode.
