| 41 | Pocketed spring comfort layer and method of making same | US14879672 | 2015-10-09 | US09943173B2 | 2018-04-17 | Richard A. Krtek; Austin G. Long; Eric Rhea; Darrell A. Richmond |
| 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. | ||||||

| 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. | ||||||

| A spring interior forming method and apparatus provides a spring interior assembler and a coil row transfer station upstream of the assembler having at least one conveyer extending therethrough. A coil former is provided at an upstream end of the conveyor and is operated through a plurality of cycles, each to feed one spring coil onto the conveyor. In one embodiment, a single former is provided with a single conveyor extending therefrom through the transfer station. In a second embodiment, two such coiler-conveyor combinations is provided. In a third embodiment, one conveyor through the transfer station is provided with two coilers, each having a feeder preferably in the form of a conveyor, that selectively feed spring coils, which may be of different types, to a cross-over station for feed onto the transfer station conveyor. In a fourth embodiment, each coiler accumulates springs at its output while awaiting queing by the cross-over station. Between consecutive cycles of the feeding of a spring onto the transfer conveyor, a stepper motor or other servo-type motor advances the conveyor a programmed distance, thereby providing the capability for obtaining different programmed spacings between coils on the rows presented by the transfer conveyor to the transfer station. | ||||||

| 51 | Apparatus for producing all metal spring cushions | US927286 | 1992-09-23 | US5289853A | 1994-03-01 | Lothar Schaefer |
| For producing an all-metal spring cushion, a knitted piece knitted from spring wire is wound in a winding sleeve (14). In the winding sleeve (14), the end of the knitted piece is fixed to the knitted roll (76) by micro-welding. In a pressing station (22), the winding sleeve (14) is flush and aligned in front of a pressing sleeve (148) of the same inner diameter. The knitted roll is pushed into the pressing sleeve (148) by a press die (162) and compressed therein to form a spring cushion. Then, the spring cushion is ejected from the pressing sleeve. | ||||||

| An apparatus for manufacturing a spring unit used for mattresses and the like is provided with a first unit for forming coiled springs sequentially out of a single wire and shaping the spring wires by arranging these coiled springs in a lateral row so that side limbs of the coiled springs are adjacent to each other, and a second unit extending across the spring wires and adapted to shape helical wires wound around the side arms of the spring wires so that the helical wires extend across the side limbs. The second unit is provided with a helical wire shaping device which includes a feeding mechanism and another mechanism for forming the straight wire fed from the feeding mechanism into the helical wires and a third mechanism for adjusting a pitch of the helical wires. The second unit is also provided with a device for supplying the helical wires while measuring and controlling the length of the helical wires in such a manner that this length substantially agrees with the width of the spring wires. Also, an end former is disposed so that it can be positioned freely in the widthwise direction of the spring wires. The end former is adapted to cut the end portion of the helical wire. | ||||||
| 53 | Wire knotting machine | US19226 | 1979-03-09 | US4223705A | 1980-09-23 | George E. Bell; John P. Gowing |
| A machine operable to twist the end portion of a cross wire around a longitudinal wire disposed at right angles to the cross wire, and then to twist the cross wire end portion about the standing portion of the cross wire, to form a "knot". The machine consists of a knotter die rotatable about the axis of the longitudinal wire to form the first twist, and to force the end portion of the cross wire operatively against an anvil configurated to form the second twist so that both twists are formed in a single operation, although the two twists lie in substantially right angled planes. This substantially doubles the speed at which the knots may be formed in automatic machinery. As optional equipment, other dies may be added for pressing the wire bend formed in the second twist, and the raw end of the cross wire, closely adjacent the longitudinal wire, so that the raw wire ends are shielded. This knot "finisher" operation is performed at a station different from that at which the knot is initially formed, so that in an automatic machine, the finishing operation does not reduce the production rate. | ||||||
| 54 | Locating means for co-operating with helical wires | US857171 | 1977-12-02 | US4156442A | 1979-05-29 | Neville Sykes |
| The invention provides a pair of bodies with operative faces that can be brought face to face. The operative face of one body is formed with a row of circular openings of uniform diameter and spaced uniformly apart. The operative face of the other body has a row of locating formations which may also comprise a row of circular openings similar to those in said one body. The openings and formations are together such as to define a passageway for receiving and locating a helical wire of pitch equal to the spacing between the centers of the openings in said one body. The helical wire can be advanced axially relative to the bodies by rotating it about its own axis. | ||||||

| A single continuous length of spring wire is formed into a continuous length spiral or helix which is subsequently folded into a wave configuration for establishing in row form, a plurality of individual spring coils disposed generally parallel one to another. Each coil in the row is connected at its opposite ends to adjacent coils by head or connector end sections. The head or connector end sections are then formed, preferably into a planar Z-shaped configuration such that the formed connector sections at the same ends of the coils are disposed in a common plane normal to the axes of the coils which they interconnect. During forming of the end sections or heads of the coils, each connector section is deformed from a looped three-dimensional attitude into the planar Z-shaped attitude by interengagement with novel forming pins and forming dies. | ||||||
