Method of making articles comprising two components hinged one to the other

Claim 1

A method of making two components as a hinged assembly comprising the steps of feeding separate strips of work stock intermittently and simultaneously into opposite portions of a phased die and operating the phased die to simultaneously form both strips and thereby press-forming two, co-planar, oppositely directed lugs on one piece of work stock, press-forming two parallel spaced apart co-directed lugs on the other piece of work stock, press-forming a clearance hole in each of two of said four lugs, press-forming a protrusion on each of the other two of said four lugs, press-forming said co-planar, oppositely directed lugs into a U-shape, then press-folding said co-directed lugs towards each other to embrace said U-shaped lugs, said protrusions being disposed in a direction so that by said folding step said protrusions are engaged respectively into associated said clearance holes, and then press-severing each of the formed portions of the assembly from the work stock to produce two components hingedly connected together with the two clearance holes and two protrusions co-axial on the hinge axis.
