Machine and method for assembling coil springs in the production of mattresses

Claim 1

A METHOD OF INTERCONNECTING THE TOP AND BOTTOM CONVOLUTIONS OF HELICAL COIL SPRINGS BY TIE WIRES HAVING S-SHAPED HOOK-LIKE PARTS, COMPRISING LOCATING AND SUPPORTING A FIRST ROW OF COIL SPRINGS, LOCATING AND SUPPORTING A SECOND ROW OF COIL SPRINGS ADJACENT THE FIRST ROW AND WITH THE CONVOLUTIONS OF THE SECOND ROW OVERLAPPING THE CONVOLUTIONS OF THE FIRST ROW, DEFORMING THE TOP CONVOLUTIONS OF THE FIRST AND SECOND ROWS SO THAT THE OVERLAPPING AND UNDERLAPPED PORTIONS THEREOF PROJECT UPWARDLY, SIMILARLY DEFORMING THE BOTTOM CONVOLUTIONS OF THE FIRST AND SECOND ROWS SO THAT THE OVERLAPPING AND UNDERLAPPED PORTIONS THEREOF PROJECT DOWNWARDLY, POSITIONING A TIE WIRE ABOVE AND BELOW THE TOP AND BOTTOM CONVOLUTIONS, RESPECTIVELY, WITH EACH TIE WIRE BEING LOCATED RELATIVELY ADJACENT AN UNDERLAPPED CONVOLUTION, ROTATING THE TIE WIRES TO CAUSE THE BASE LOOPS OF THE UNDERHOOK-LIKE PARTS TO ENGAGE WITH THE ARCS OF THE UNDERLAPPED CONVOLUTIONS AND THEN PASS THROUGH SPACES BETWEEN THE ARCS FORMED BY THE UNDERLAPPING AND OVERLAPPED PORTIONS OF THE CONVOLUTIONS, AND THEN EFFECTING A SEPARATING ACTION OF THE FIRST AND SECOND ROWS OF COIL SPRINGS TO CAUSE THE DEFORMED CONVOLUTIONS THEREOF TO RETURN TO A CO-PLANAR RELATION, WHEREBY THE OUTER LOOPS OF THE HOOK-LIKE PARTS OF THE TIE WIRES WILL ENGAGE THE ARCS OF THE OVER-LAPPING CONVOLUTIONS AND THEREBY INTERCONNECT THE HELICAL COIL SPRINGS.

Claim 2

A METHOD OF INTERCONNECTING THE TOP AND BOTTOM CONVOLUTIONS OF HELICAL COIL SPRINGS BY TIE WIRES HAVING S-SHAPED HOOK-LIKE PARTS, COMPRISING LOCATING AND SUPPORTING A FIRST ROW OF COIL SPRINGS, LOCATING AND SUPPORTING A SECOND ROW OF COIL SPRINGS ADJACENT THE FIRST ROW AND WITH THE CONVOLUTIONS OF THE SECOND ROW OVERLAPPING THE CONVOLUTIONS OF THE FIRST ROW, DEFORMING THE TOP CONVOLUTIONS OF THE FIRST AND SECOND ROWS SO THAT THE OVERLAPPING AND UNDERLAPPED PORTIONS THEREOF PROJECT UPWARDLY, SIMILARLY DEFORMING THE BOTTOM CONVOLUTIONS OF THE FIRST AND SECOND ROWS SO THAT THE OVERLAPPING AND UNDERLAPPED PORTIONS THEREOF PROJECT DOWNWARDLY, POSITIONING A TIE WIRE ABOVE AND BELOW THE TOP AND BOTTOM CONVOLUTIONS, RESPECTIVELY, WITH EACH TIE WIRE BEING LOCATED RELATIVELY ADJACENT AN UNDERLAPPED CONVOLUTION, ROTATING THE TIE WIRES TO CAUSE THE BASE LOOPS OF THE UNDERHOOK-LIKE PARTS TO ENGAGE WITH THE ARCS OF THE UNDERLAPPED CONVOLUTIONS AND THEN PASS THROUGH SPACES BETWEEN THE ARCS FORMED BY THE UNDERLAPPING AND OVERLAPPED PORTIONS OF THE CONVOLUTIONS, AND THEN EFFECTING A SEPARATING ACTION OF THE FIRST AND SECOND ROWS OF COIL SPRINGS TO CAUSE THE DEFORMED CONVOLUTIONS THEREOF TO RETURN TO A CO-PLANAR RELATION, WHEREBY THE OUTER LOOPS OF THE HOOK-LIKE PARTS OF THE TIE WIRES WILL ENGAGE THE ARCS OF THE OVER-LAPPING CONVOLUTIONS AND THEREBY INTERCONNECT THE HELICAL COIL SPRINGS.
