Abstract
A machine for assembling polyhedron devices comprising lifting means for lifting a polyhedron blank from a supply stack. Forming means receive the polyhedron blank from the lifting means and form the polyhedron into a polyhedron shaped article. A resilient member inserter means inserts a resilient member, such as a rubber band, into the polyhedron blank on the forming means so that the resilient member will bias the polyhedron shaped article into its formed configuration. Preferably the polyhedron assembling machine of the present invention further comprises adhesive applying means for applying adhesive to the polyhedron blank in the forming means. The machine of the present invention may further comprise a polyhedron blank holder means for holding a supply stack of polyhedron blanks to be lifted by the lifting means. The invention also comprehends a method of making a collapsible polyhedron article.
