ABSTRACT:
Method of, and apparatus for continuously manufacturing elongate articles with a plurality of segments of basically same and slightly different cross-sections, such as upper and side segments of automobile molding members. The apparatus includes a single die head formed with a common orifice and at least one additional orifice, as well as a device for selecting and controlling operational modes of the apparatus. The device may comprise a guide device which is movable between different positions corresponding to respective operational modes of the apparatus, and which serves to guide synthetic resin material extruded from the additional orifice. The guide member maintains in its one position a spaced relationship of synthetic resin materials extruded from the orifices to form one segment, and causes in another position the synthetic resin materials to adhere with each other to form another segment.
