Abstract
A die for a profile extrusion for partly varying the profile of articles during a molding operation is provided. The die comprises a stationary die assembly and movable die assembly slidable on a surface thereof. Each die assembly includes an outlet port for defining a part of products. The stationary die further includes an opening functioning as a third outlet port. The third outlet port may vary its opening shape according to the sliding of the movable die on a surface of the stationary die during an extrusion molding operation with the result that the width of a connecting portion between the parts formed by the outlet port of the movable and the stationary die is varied. It will be noted that an article may be produced which has variably sized portions.
