Abstract: An exemplary pocket spring assembly comprises a plurality of elongate fabric tubes disposed adjacent each other. Each fabric tube has a plurality of pockets, with at least some of the pockets of adjacent fabric tubes being welded together at midpoints on the adjacent pocket. Further, a spring is disposed in each of the pockets.

Abstract: A mattress ventilator is formed by a disk of sheet metal drawn with an array of tubular protuberances having tubular cross-sections which are very small compared with the area of the disk, open ends of the tubular protuberances being retrovertable by a die into roses for holding the disk in a mattress border. Such a ventilator can be applied to a mattress border by pressing the tubular protuberances through the border from an outer surface and retroverting the distal ends of the protuberances to form roses crimped against an inner surface of the border. The penetrations of the material of border are limited to the size of the tubular protuberances, and the perforated areas are supported and covered by the disk and act as stress reliefs for each other.

Abstract: In the production of a pocket spring assembly, fabric is secured along multiple parallel seam zones so as to form a quilt defining a plurality of parallel fabric tubes connected to each other at uniformly spaced intervals. The tubes so formed are supported on guides extending longitudinally through the tubes, portions of the quilt are repeatedly drawn from the guides at their one ends and folds formed in each layer of fabric in the drawn off portion are secured to form pockets from the drawn off portions of the quilt, and precompressed coil springs are passed through the guides and released into the pockets between each drawing of the quilt, with their axes perpendicular to both the axes of the fabric tubes and the direction of advancement of the quilt, so that secured folds in the fabric of the tubes in front of and behind the released springs retain them in the pockets.

Abstract: In the production of a pocket spring assembly, two layers of fabric are secured together along multiple parallel seam zones so as to form a quilt defining a plurality of parallel fabric tubes, the tubes so formed are supported on guides extending longitudinally through the tubes, portions of the quilt are repeatedly drawn from the guides at their one ends and folds formed in each layer of fabric in the drawn off portion are secured to form pockets from the drawn off portions of the quilt, and precompressed coil springs are passed through the guides and released into the pockets between each drawing of the quilt, with their axes perpendicular to both the axes of the fabric tubes and the direction of advancement of the quilt, so that secured folds in the fabric of the tubes in front of and behind the released springs retain them in the pockets. Spaced longitudinal slits are formed in the seam zones, the slits permitting the fabric to envelope the tubes.
