Abstract
A pocket spring assembly 1 has a core 1′ of a pocket spring assembly formed by a plurality of first, adjacent and interconnected pocket spring webs 2 and at least one second pocket spring web 4 connected to the core. Additional strips are provided connecting the at least one pocket spring web 2 with the first and second layers of textile material, respectively, provided on the core 1′. A mattress has a pocket spring assembly and a method is for manufacturing such an assembly.
Claims10
A pocket spring assembly comprising:
- a plurality of first pocket spring webs, wherein adjacent first pocket spring webs are joined together to form a core of the pocket spring assembly,
- a first layer of textile material and a second layer of textile material attached to a first and second surface of the core of the pocket spring assembly, respectively, wherein the layers of textile material extend along an entire area of said first and second surfaces of the core of the pocket spring assembly,
- at least one second pocket spring web attached to a first lateral surface of said core of the pocket spring assembly, forming a pocket spring assembly, wherein said second pocket spring web extends perpendicularly to a direction of the first pocket spring webs,
- wherein springs in the first pocket spring webs have different stiffness characteristics than the springs in said at least one second pocket spring web, wherein:
- the first layer of textile material and the second layer of textile material do not extend beyond the area of said first and second core surfaces of the pocket spring assembly, the pocket spring assembly further comprises:
- a first strip of textile material directly attached to the first layer of textile material and having a portion extending laterally beyond the core of the pocket spring assembly which is directly attached to at least one second web of pocket springs, and
- a second strip of textile material directly attached to the second layer of textile material and having a portion extending laterally beyond the core of the pocket spring assembly which is directly attached to the at least one second web of pocket springs,
- wherein the portion of the first strip of textile material and second strip of textile material extending laterally beyond the core of the pocket spring assembly has a width substantially equal to a width of the at least one second web of pocket springs.

A method of manufacturing a pocket spring assembly comprising the steps of:
- a) providing a core of the pocket spring assembly, said core of the pocket spring assembly comprising a plurality of first pocket spring webs, wherein adjacent first pocket spring webs are joined together to form said core of the pocket spring assembly,
- b) attaching a first layer of textile material and a second layer of textile material to first and second surfaces of said core of the pocket spring assembly, respectively, said layers of textile material extending along an entire area of said first and second surfaces of the core of the pocket spring assembly, wherein the first layer of textile material and the second layer of textile material do not extend beyond the area of said first and second surfaces of the core of the pocket spring assembly,
- c) providing at least one second pocket spring web in which springs have different stiffness characteristics than springs in the first pocket spring webs,
- d) attaching a first strip of textile material directly to a first layer of textile material along a longitudinal direction of the core of the pocket springs, such that a portion of said first strip extends beyond the core of the pocket spring assembly,
- e) forming the pocket spring assembly by attaching said at least one second web of pocket springs to a first lateral surface of the core of the pocket spring assembly and directly to a portion of the first strip of textile material extending beyond the core of the pocket spring assembly, the portion of the first strip of textile material extending beyond the core of the pocket spring assembly has a width substantially equal to a width of the at least one second web of pocket springs, said at least one second web of pocket springs extending perpendicularly to a direction of extension of the first webs of pocket springs,
- f) attaching a second strip of textile material directly to at least one second web of pocket springs and directly to the second layer of textile material.
