ABSTRACT:
Paramagnetic articles such as a stem (14) and an armature (17) are placed into mutual coextensive alignment with a gap (19) of a predetermined width between adjacent portions of such articles. To repetitively establish the predetermined gap between successive groups of such articles, a first of such articles is guided tangentially into a magnetic field. A resulting force on such article (14) draws the article against a first stop surface. The article becomes magnetically polarized, such that when the second article, such as the armature (17) is guided into coextensive alignment with the first article, the second article becomes attracted to the first article to be drawn against a stop surface opposite to and spaced from the first stop surface by a dimension equal to the predetermined gap width.
