Abstract
Abstract An assembly of flexible strip articles, flexible metallic bands, and metallic surface all of which being magnetically fixedly held together for providing a stable molding apparatus about a form. One of the strip articles of the assembly comprises an elongated strip of magnetic material sandwiched between a pair of coextensively extending metal members one of which may include a base flange. An additional strip article composed of the magnetic material may be included as part of the assembly. The metallic bands are magnetically secured to the first strip article which in turn is magnetically secured to the metallic surface whereby such assembly constitutes a molding device.
