Abstract
Method of for continuously manufacturing a plurality of kinds of elongate articles with basically same and slightly different cross-sections, such as upper and side segments of automobile molding members. The method employs a single die plate 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 movable guide member which is movable between different positions corresponding to respective operational modes of the apparatus, and 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 kind of elongate articles, and causes in another position the synthetic resin materials to adhere with each other to form another kind of elongate articles.
