Abstract
A continuous strip of thermoplastic articles, such as electrical connecting device housings, has first and second portions defined by bands which extend along the entire length of the strip. The first band is of a first thermoplastic material which has optimum properties and characteristics for the parts of the articles which lie in the first band and the second band is of a second thermoplastic material which has optimum properties and characteristics for those portions of the article which lie in the second band of the continuous strip. In the case where the articles are connector housings, the first band may be of a material which has superior crimping characteristics while the second band may be of a material having optimum firmness and strength. The strip is manufactured by a continuous thermoplastic molding process in which the two materials are continuously extruded through a nozzle and into an endless series of side-by-side cavities in a molding wheel while the surface of the wheel was continuously moving past the nozzle.
