A first feeder 1012 is used to feed a first string of pocketed springs, comprising a first pocket and a plurality of springs of a first type, to a first conveyor 1011. A second feeder 1013 is used to feed the first conveyor 1011 with a second string of pocketed springs comprising a second pocket and a plurality of second springs different from the first springs.

A first feeder 1012 and a second feeder 1013 alternately feed first and second pocketed spring string segments to the first conveyor 1011 to form a first pocketed spring string 201 on the first conveyor 1011 that includes only the first pocketed spring string segment, or the first pocketed spring string 201 that includes only the second pocketed spring string segment, or the first pocketed spring string 201 that includes both the first and second pocketed spring string segments. The first sealing mechanism 1014 may seal together a first pocketed spring string segment and a second pocketed spring string segment in a first pocketed spring string 201 that includes both the first pocketed spring string segment and the second pocketed spring string segment.

It will be appreciated that when the spring core 200 to be assembled requires a first string 201 comprising only a first string section of pocketed springs, the first feeder 1012 feeds the first conveyor 1011 with the first string section of pocketed springs and the second feeder 1013 is deactivated. Thus, all of the first string of pocketed springs 201 are first springs.

When the spring core 200 to be assembled requires the first string 201 comprising only the second string section, the second feeder 1013 feeds the second string section to the first conveyor 1011 and the first feeder 1012 stops. Thus, the first string of pocketed springs 201 are all second springs.

When the spring core 200 to be assembled requires a first string 201 comprising a first string section of pocketed springs and a second string section of pocketed springs, the first feeder 1012 and the second feeder 1013 are operated simultaneously and alternately feed the first string section of pocketed springs and the second string section of pocketed springs onto the first conveyor 1011 to form a first string 201 comprising a first string section of pocketed springs and a second string section of pocketed springs.

A second sealing mechanism 1044 can seal together a third pocketed spring string section and a fourth pocketed spring string section in a second pocketed spring string 202 that includes both the third pocketed spring string section and the fourth pocketed spring string section.

It will be appreciated that when the spring core 200 to be assembled requires a second string 202 of pocketed springs comprising only a third string section, the third feeder 1042 feeds the third string section to the second conveyor 1041 and the fourth feeder 1043 is deactivated. Thus, the second springs in the second string of pocketed springs 202 are all third springs.

When the spring core 200 to be assembled requires the second string 202 of pocketed springs including only the fourth string section, the fourth feeder 1043 feeds the fourth string section to the second conveyor 1041, and the third feeder 1042 stops operating. Thus, the second springs in the second string of pocketed springs 202 are all fourth springs.

When the spring core 200 to be assembled requires a second string 202 comprising a third string section of pocketed springs and a fourth string section of pocketed springs, the third feeder 1042 and the fourth feeder 1043 operate simultaneously and alternately feed the third string section of pocketed springs and the fourth string section of pocketed springs onto the second conveyor 1041 to form the second string 202 comprising the third string section of pocketed springs and the fourth string section of pocketed springs. Thus, there are both third and fourth springs in the second string of pocketed springs 202.

A third sealing mechanism 1064 may seal together a fifth pocketed spring string section and a sixth pocketed spring string section in a third pocketed spring string 203 that includes both the fifth pocketed spring string section and the sixth pocketed spring string section.

It will be appreciated that when the spring core 200 to be assembled requires a third string 203 comprising only a fifth string section of pocketed springs, the fifth feeder 1062 feeds the third conveyor 1061 with the fifth string section of pocketed springs, and the sixth feeder 1063 is deactivated. Thus, the third springs in the third string of pocketed springs 203 are all fifth type springs.

When the spring core 200 to be assembled requires a third string 203 comprising only a sixth string section of pocketed springs, a sixth feeder 1063 feeds the sixth string section to the third conveyor 1061 and the fifth feeder 1062 stops. Thus, the third springs in the third string of pocketed springs 203 are all sixth springs.

When the spring core 200 to be assembled requires a third string 203 of pocketed springs comprising a fifth and a sixth string section, the fifth 1062 and sixth 1063 feeder work simultaneously and alternately feed the fifth and sixth string sections onto the third conveyor 1061 to form the third string 203 comprising the fifth and sixth string sections. Thus, there are both fifth and sixth springs in the third string of pocketed springs 203.
