摘要： A resilient unit has strings of individual coil springs (not shown) inside pockets 120 are arranged in an array. The strings together form a spring unit and are each secured to a common cover sheet S, which comprises a non-woven elastic fabric. It is welded ultrasonically or thermally whilst under tension in one or both of its major dimensions—i.e. in-plane—to the pockets 120, the material of which is substantially inelastic and non-woven. In this example the welds, labelled W, are located substantially centrally with respect to the generally circular end surfaces of the pockets.

摘要： In order to manufacture an innerspring unit (31) comprising pocketed springs and having an increased stability at its edge regions, in a first step, an innerspring main body (30) comprising a plurality of first strings (14) of pocketed springs is provided. In a subsequent second step, at least one second string (13c, 13d) of pocketed springs is attached to a lateral surface of the innerspring main body (30), so that the at least one second string (13c, 13d) of pocketed springs extends in a longitudinal direction of the innerspring main body (30). The springs (13) of the at least one second string (13c, 13d) of pocketed springs have a spring characteristic or a spring geometry different from the springs of the plurality of first strings of the innerspring main body (30). The at least one second string (13c, 13d) of pocketed springs forms together with the innerspring main body (30) the innerspring unit (31).

摘要： A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

摘要： Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs modules, comprising more than two pocketed springs surrounding a central hole, can be automatically loaded onto an assembler; pocketed spring-surrounded openings can be automatically aligned with welding phalanges; and probe/anvil welding pairs can be inserted into modules in different rows of modules, closed around polymer pocket fabric, and activated to weld rows of modules together without glue; without a user manually loading rows of modules onto the assembler.

摘要： A foldable tension spring mattress, wherein a vertical pressure is converted into a tension by means of a wrapping blanket; the tension acts on the periphery of a spring net and is converted into a pulling force acting on coil springs and penetrating springs; and then the pulling force is uniformly dispersed to each of the coil springs, so that the local overstressing of the coil springs and the penetrating springs is avoided, thereby preventing the spring net and the penetrating springs from being arched and sunken. As a result, the mattress may keep good elasticity all the time, which further increases the comfort level of the spring mattress. The present solution may alleviate the plastic deformation of the coil springs to further increase the comfort level of the spring mattress and improve the elasticity and durability of the spring mattress.

摘要： A pocket spring core as well as a method for producing a pocket spring core for use in the manufacture of mattresses or furniture upholstery. The pocket spring core has a plurality of springs, a number of which lie in a row one behind the other in respective flexible pockets, forming a bank of springs, and a number of adjacent banks of spring, which together form a supporting surface, are interconnected. The springs of at least one region of the supporting surface have different springing characteristics from the springs of the neighboring regions. At least one part of the individual banks of springs consists of bank portions with differing spring characteristics, the pocketed springs of each bank portion are identical, at least some of the neighboring portions of adjacent banks of springs are of different lengths and the neighboring portions of adjacent banks of springs are interconnected.

摘要： The invention relates to a furniture device configured to receive the weight of a being, said furniture device having a holding arrangement and at least one section. The section comprises a base, a movable plate element, a moving mechanism and at least one elastic device. The plate element is configured to interact with the at least one elastic device and to be moved by the moving mechanism in respect to the base in order to adjust the firmness of the at least one elastic device. The elastic device comprises a pocket made of a fabric, and an elastic member, the elastic member is arranged within said pocket, the pocket is attached to adjacent pockets whereby the attachment is formed so that adjacent elastic devices may move independently from one another along a distance (A), as measured from a free end of the elastic device and in a direction perpendicular to the plate member. The holding arrangement comprises a connecting portion and a holding member, which is connected to the base or the plate element and connected to the at least one elastic device via the connecting portion, such that the at least one elastic member is compressed and relaxed respectively over its entire length during movement of the plate element upwards and downwards. The connecting portions are arranged on a straight line, which extends through the centre of two or more attached elastic devices and the holding member is a flexible thread or string, which is directly connected to each connecting portion.

摘要： A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have pockets of different sizes before springs are inserted therein to accommodate for the fabric stretching due to some of the springs exerting greater force on the fabric than other springs. The ability to create pockets of different sizes enables springs of different strengths to be inserted into the pockets along a string, the string having a generally uniform height after assembly.
