Abstract:
A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.
Abstract:
A posturized comfort layer for a bedding or seating product has different sections of different firmness due to different mini coil springs within the sections. The springs may be individually pocketed between two sheets of non-woven polypropylene fabric joined with circular seams or rectangular seams. Each circular seam joins opposed pieces of fabric around one of the mini coil springs with curved segments. Alternatively, rectangular seams join opposed pieces of fabric around each of the mini coil springs with linear segments. Regardless of the shape of the seams, the different firmness of the different sections of the comfort layer may be due to the mini-coil springs contained in the pockets.
Abstract:
A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The strings of springs may extend from head-to-foot or side-to-side of the product. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart.
Abstract:
An apparatus for ventilating a web of material used in the manufacture of pocketed springs may be removably attached to a pocket coiler. The apparatus has an upper movable portion which pivots relative to a stationary portion. The stationary portion may be removably attached to the pocket coiler. Each portion has at least one roller, a web of material passing between the rollers during use. One of the rollers may have protrusions to create openings in the material before the material enters the pocket coiler.
Abstract:
A bedding or seating product comprises a pocketed spring assembly comprising a plurality of parallel strings of individually pocketed springs. The product may have individual inserts between adjacent strings of springs. Adjacent individually pocketed springs are separated from each other by at least one separating seam. Each of the separating seams comprises a pair of Y-shaped or U-shaped seams which may be joined together or spaced apart.
Abstract:
A comfort layer for a bedding or seating product has slow-acting pockets characterized by the individual springs of the comfort layer being pocketed with either semi-impermeable or non-permeable fabric. Each seam joining opposed plies of fabric around each of the coil springs of the comfort layer may be segmented, allowing air to flow between the segments, thereby increasing the luxury “feel” of the comfort layer. The method of making the comfort layer includes compressing the springs and creating pockets with a welding horn and an anvil.

Abstract:
Disclosed herein is a method of making a spring core (12) for a bedding or seating product (10). The spring core (12) has coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one arcuate leg (76) longer than the other (78), the legs (76, 78) being joined by a connector (80) having an arcuate bump (81) therein. The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to being wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.
