Claims
- 1. A method of assembling a coil spring unit, said method comprising the steps of
- forming a series of rows of coil springs, each of said rows being formed from a single continuous length of wire, adjacent springs withins aid row being directly connected one with the other through use of connector sections,
- connecting said continuous coil spring rows together in matrix configuration, and
- thereafter selectively disconnecting at least some of the coil springs within at least some of the rows from those coil springs adjacent thereto in order to provide a finished coil spring unit having at least a portion of the coil springs separate and apart from one another in at least a portion of said unit's rows.
- 2. A method as set forth in claim 1, said connector sections connecting end face loops of adjacent coil springs, each connector section at least partially defining the two adjacent end face loops of an adjacent pair of coil springs.
- 3. A method as set forth in claim 2, said disconnection step establishing free ends for said end face loops, and further comprising the step of
- forming each coil spring's free ends so that said free ends are directed inwardly into the barrel interior of said coil spring.
- 4. A method as set forth in claim 1, said method comprising the step of
- disconnecting all coil springs within each row, said finished coil spring unit having all intermediate coil springs therewithin separate and apart from one another.
- 5. A method as set forth in claim 1, said method comprising the step of
- disconnecting intermediate coil springs within only a portion of said rows, said step thereby resulting in a portion of rows in which adjacent coil springs remain directly connected one with another and a portion of rows in which adjacent coil springs are separate and apart from one another.
- 6. A method as set forth in claim 5, said method comprising the step of
- establishing a center section in said matrix configuration at which intermediate coil springs are not disconnected one with the other, and
- establishing at least one end section within said matrix configuration at which intermediate springs are disconnected separate and apart one from another.
