Disclosed herein is a bedding or seating product (10) having a spring core (12) comprising 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 leg (76) longer than the other (78), the legs (76, 78) being joined by an arcuate connector (80). 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 be wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.

Apparatus and methods for use in the manufacture of a spring unit for incorporation into an upholstered article, for example, a mattress, cushion or the like. A coil interlinking process comprises compressing a first coil to define a clearance extending a second coil passed the first coil via the clearance, allowing the first coil to extend across the clearance, and contracting the second coil such that the second coil engages the first coil thereby interlining the first and second coils. The invention also relates to a coil interlinking apparatus.

| Machinery for automated manufacture of formed wire structures (2) such as innerspring assemblies for mattresses and seating and flexible support structures includes one or more coil formation devices (201, 202) configurable to produce helical spring coils having a terminal convolution which extends beyond an end of the coil. The machinery includes a conveyor system (301, 302) having a plurality of flights slidably mounted upon a continuous track and connected to a chain and driven by an index driver. The flights are connected to a drive system which enables variable spacing between the flights so that the conveyor can be loaded with articles at one spacing interval and be unloaded at a different interval. | ||||||

| Machinery for automated manufacture of innerspring assemblies (1) for mattresses and flexible support structures includes coil formation devices (201, 202) configured to produce generally helical spring coils (2) having a terminal convolution (26) which extends beyond an end of the coil and a conveyor system (301, 302) having a plurality of flights (308) connected to a chain (315) and driven by an index driver (320) which delivers formed coils to an innerspring assembler (500). A coil forming block (208) on a coiler machine has a cavity (218) in which a terminal convolution of the coil is formed, and from which the coil is cut by a cutter (212) which extends into the cavity. Coil head formation dies (2000) at coil head forming stations (230, 240) of the coil forming machine also have a cavity (2010) for receiving a terminal convolution of a coil, and flanges (2007, 2008) which surround the cavity and provide a punch set for punches (232) which form a coil head proximate to the terminal convolution in the die. | ||||||

| A spring interior forming method and apparatus (30, 30a, 50, 80) provides a spring interior assembler (35, 35a, 55) and a coil row transfer station (40, 40a, 52) upstream of the assembler having at least one conveyor (35, 35a, 51) extending therethrough. A coil former (31, 31a, 31b, 56a, 56b) is provided at an upstream end of the conveyor and is operated through a plurality of cycles, each to feed one spring coil (32, 32a, 32b, 54a, 54b) onto the conveyor. Between consecutive cycles of the feeding of a spring onto the transfer conveyor (51), a stepper motor (53) or other servo-type motor advances the conveyor (51) a programmed distance, thereby providing the capability for obtaining different programmed spacings between coils on the rows presented by the transfer conveyor (51) to the transfer station (52). | ||||||

| In order to manufacture an all-metal spring-type die cushion, the invention calls for a knitted fabric made of spring wire to be taken up in a winding sleeve (14). In the winding sleeve (14), the end of the knitted fabric is held in place on the fabric coil (76) by micro-welding. The winding sleeve (14) is aligned flush with a compression tube (148) with the same internal diameter at a press station (22). By means of a punch (162), the fabric coil is pushed into the compression tube (148) where it is compressed into a spring-type die cushion. The spring-type die cushion is subsequently pushed out of the compression tube. | ||||||

| The apparatus for manufacturing combined springs according to the present invention is provided with a first unit for forming coiled springs (23) sequentially out of a single wire and shaping spring wires (20) obtained by arranging these coiled springs (23) in a lateral row so that side arms (25) of the coiled springs (23) are adjacent to each other, and a second unit extending across the spring wires (20) and adapted to shape spiral wires wound around the side arms (25) of the spring wires (20) so that the spiral wires extend across the side arms (25). The second unit is provided with a spiral wire shaping means, a supply means (251) for supplying spiral wires while measuring and controlling the length of the spiral wires, which are being supplied, in such a manner that this length substantially agrees with the width of the spring wires, and an end forming means (201) which is disposed so that the end forming means can be positioned freely in the widthwise direction of the spring wires, and which is adapted to cut the end portion of a spiral wire which is on the front side thereof with respect to the direction of feeding the spiral wires and projects in the widthwise direction of the spring wires, and then bends the spiral wire. | ||||||

| Afin de fabriquer une presse-tôle à ressort tout-métal, une toile métallique tissée en fil d'acier à ressort est enroulée sur un mandrin (14) d'enroulement, l'extrémité de la toile métallique étant fixée par micro-soudage à la bobine (76) de toile métallique enroulée dans le mandrin d'enroulement (14). Dans une station de moulage par compression (22), le mandrin d'enroulement (14) est positionné en alignement précis devant une douille de compression (148) de même diamètre intérieur, à fleur de celle-ci. Un fouloir (162) pousse la bobine de toile métallique enroulée dans la douille de compression (148), où elle est comprimée jusqu'à former une presse-tôle à ressort. La presse-tôle est ensuite éjectée de la douille de compression. | ||||||
