Abstract
A method of assembling strings of pocketed coil springs into an innerspring assembly which may be used as the core of a mattress, cushion or similar body support foundation uses a fabric material, preferably having an adhesive component, between rows of pocketed coil springs. The adhesive material serves to bond the rows of springs to each other and to position them relative to one another to prevent expansion and/or contraction of the spring assembly.
Claims28
A method of making a spring assembly comprising:
- encasing a plurality of coiled springs in individual pockets of material to form a string of pocketed coil springs with opposing outwardly facing surfaces;
- juxtaposing a plurality of the strings of pocketed coil springs in side-by-side fashion with longitudinal axes of the springs being generally parallel to one another;
- interposing a layer of material between adjacent strings of pocketed coil springs;
- tautening the layer of material;
- and
- adhesively joining the adjacent strings of pocketed coil springs together with the layer of material therebetween.
A method of making a spring assembly comprising:
- encasing a plurality of coiled springs in individual fabric pockets to form a string of pocketed coil springs with opposing outwardly facing surfaces;
- adding a layer of fabric material to at least one of the facing surfaces;
- tautening the layer of fabric material;
- adhesively joining the layer of fabric material to the at least one facing surface;
- juxtaposing a plurality of the strings of pocketed coil springs in side-by-side fashion with longitudinal axes of the springs being generally parallel to one another, and with at least one outwardly facing surface of adjacent strings having the layer of fabric material;
- and
- adhesively joining the strings of pocketed coil springs together.
A method of making a spring assembly comprising:
- encasing a plurality of coiled springs in individual pockets of material to form a string of pocketed coil springs with opposing outwardly facing surfaces;
- juxtaposing a plurality of the strings of pocketed coil springs in side-by-side fashion with longitudinal axes of the springs being generally parallel to one another;
- interposing a layer of adhesive netting between adjacent strings of pocketed coil springs;
- tautening the layer of adhesive netting;
- and
- joining the adjacent strings of pocketed coil springs together with the adhesive netting.
A spring assembly comprising:
- a plurality of strings of coiled springs in individual fabric pockets in side by side relation with longitudinal axes of the springs being generally parallel to one another;
- and
- a taut layer of fabric material between each adjacent pair of strings of coiled springs, the adjacent strings of coiled springs and the layer of fabric being adhesively joined together.
A spring assembly manufactured from a method comprising:
- encasing a plurality of coiled springs in individual pockets of material to form a string of pocketed coil springs with opposing outwardly facing surfaces;
- juxtaposing a plurality of the strings of pocketed coil springs in side-by-side fashion with longitudinal axes of the springs being generally parallel to one another;
- interposing a layer of fabric material between adjacent strings of pocketed coil springs;
- tautening the layer of fabric material;
- and
- adhesively joining the adjacent strings of pocketed coil springs together with the layer of fabric therebetween.
