Improved adhesive bonding of strings of pocketed coil springs

摘要

A method and system for manufacturing a spring core by adhesively bonding strings of pocketed coil springs together utilizes a moving adhesive applicator for depositing adhesive onto a moving string of pocketed coil springs. Subsequently, individual strings are adhesively bonded to similar strings to form the spring core of pocketed coil springs. The moving applicator may take one of any number of various embodiments which include reciprocating movement, rotational movement, pivotal movement and/or linear translational movement for spraying a pattern of adhesive onto the moving string of pocketed coil springs.
