Title:
MACHINERY FOR AUTOMATED MANUFACTURE OF INNERSPRING ASSEMBLIES
Document Type and Number:
WIPO Patent Application WO2000015369
Kind Code:
A9
Abstract:
Machinery for automated manufacture of formed wire structures such as innerspring assemblies for mattresses includes coil formation devices (201, 202), a conveyor system (301) having a plurality of flights (308) slidably mounted upon a track (306) and connected to a chain (315) driven by an index driver (320), and an innerspring assembler (500) having first and second sets of coil-engaging dies (504a, 504b) in a parallel arrangement. The dies are mounted upon carrier bars (506a, 506b) which are vertically translated within the assembler to diverge the upper and lower dies of a set for positioning a row of uncompressed coils therebetween, and to converge the dies upon a row of coils to compress and securely hold the coils in a row. An indexer assembly (700) laterally translates the carrier bars whereby the lateral position of the first and second die sets can be exchanged to provide continuous interconnection of rows of coils.
