Abstract (en)
A support member 3 of metallic or plastics material is placed in a tool cavity against an imperforate blade member 1 of stainless steel, backed by a die 4 having through holes 6. A punch 9 is impacted against the support member, which undergoes plastic deformation and pierces the blade member locally and is extruded through the blade into the holes 6 to form projections which are subsequently riveted over to secure the assembly.
