Abstract
A pocket spring assembly 1 includes a core 1′ of a pocket spring assembly formed by a plurality of adjacent first pocket spring webs 2 and at least one second pocket spring web 4 attached to the core. Additional strips (6) are provided connecting the at least one pocket spring web 2 with the first layer (3), while on the other side the pocket spring webs 4 are attached to the extending parts of the textile layer. The layers 3,3′ are attached to the core 1′. A mattress contains 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, 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 springs in said at least one second pocket spring web,
- a first strip of textile material which is attached to at least one said second pocket spring web and to the first layer of textile material, and the second layer of textile material has a part extending beyond the core of the pocket spring assembly to which is attached said at least one second pocket spring web.
A method of manufacturing a pocket spring assembly comprising the steps of:
- a) providing a core of the pocket spring assembly, wherein said core of the pocket spring assembly comprises 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, wherein the first layer of textile material covers the first surface of the pocket spring core and does not extend beyond a perimeter, while the second layer of textile material has a portion extending beyond 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 strip of textile material to said at least one second pocket spring web in a plane parallel to a plane of the first layer of textile material, wherein after attachment said strip of textile material has an unattached portion extending beyond a surface where said strip is attached to the at least one second pocket springs web,
- e) forming a pocket spring assembly by attaching said at least one second pocket spring web obtained in step (d) to a first lateral surface of the core of the pocket spring assembly so that said unattached extending part of the strip of textile material is attached to the first layer of textile material and, on an opposite side, said at least one second pocket spring web is attached to a part of the second layer of textile material extending beyond the core of the pocket spring assembly.
