Abstract
A resilient unit is fed as a continuous web (18) through first and second tensioning rollers (20, 22) to a winding roller (24). The winding roller is driven at a first speed, and one or both of the tensioning rollers is also driven, but at a second speed which is less than the first speed - i.e. slower than that of the winding roller. The difference is speeds causes tension to be applied to the material of the resilient unit which stretches the resilient unit and in turn compresses the resilient elements in their pockets. The result is that the resilient unit becomes compressed in its through thickness direction - the axial direction of the springs - before it is wound into the winding roller. The resilient unit extends in length in a longitudinal direction in which tension is applied. The extension in length is substantially proportional to a reduction in a thickness of the resilient unit.

Accompanying drawing explanation
By reference to the accompanying drawings, by means of only the mode of embodiment, the present invention is described, wherein:
Fig. 1 a and 1b is the schematic diagram of a part for the Flexible element be applicable to according to device of the present invention or method;
Fig. 2 is the lateral plan of compression set according to an embodiment of the invention; And
The schematic diagram of a part for elastomeric material before Fig. 3 a and 3b is respectively compression and after compression.
Detailed description of the invention
See Fig. 1 a and 1b, the figures illustrate a part for the Flexible element of bagged-spring unit form, be usually labeled as 10.This Flexible element comprises some springs 12 being arranged to array, and each spring is wrapped in the bag of himself that formed between the material layer of superimposition.Described layer separates, and described spring is in therebetween, and the select location 16 place weld together of described layer between adjacent springs, thus form waffle-like pattern.Application number is that the international patent application of WO2007/031774 describes a kind of method manufacturing this bagged-spring unit in detail, wherein said spring is compressed and is then pushed between material layer, and the spaced position weld material layer between described spring is to form the bag of the separation being used for spring.
Have been found that the excess stock around due to spring, the position of welding and spring can compressibi1ity immediately, this bagged-spring unit can do thinner, namely pulls material layer can compress described spring by the direction of the axle along spring described in crosscut.
Such as, if spring is cone-type spiral wire spring, so it can be compressed to largely, makes the degree of depth of this spring be approximately the thickness of a coil, i.e. the thickness of metal filament self.
Fig. 2 schematically show the device for compressing described Flexible element.This Flexible element passes through the first and second take-up rolls 20,22 to the charging of coiling roller 24 with continuous print net 18.Drive this coiling roller with First Speed, and simultaneously to be less than First Speed, to be namely slower than the second speed of the speed of this coiling roller, to drive one or two take-up roll.
Velocity contrast cause to Flexible element material apply pulling force, this pulling force stretched described Flexible element and then elastic element is compressed in its bag.As a result, before this Flexible element is coiled in coiling roller, described Flexible element is compressed along the direction running through its thickness gradually, i.e. the axis direction of spring.The length of Flexible element extends along the longitudinal direction applying pulling force.The reduction of the thickness of the extension of length and this Flexible element is roughly proportional.
Servocontrol (not shown) can be applied on one or more driven voller, to guarantee its relative velocity, and therefore make the pulling force in material remain on the level of constant.
Drive two take-up rolls 20 and 22 to be not necessary simultaneously.
Under tension, this Flexible element roughly flattens, and degree depends on the degree of the pulling force applied in running restriction.This bag becomes general flat, and depends on the welding of layer or the pattern of bonding that form this bag, reverts to the shape that it keeps at first during manufacture.When being involved in the Flexible element net of aequum on described roller, tying up or wrapping up net volume, to prevent from scattering.
Fig. 3 a and 3b respectively show a part for the Flexible element compressing front and back in the device of Fig. 2.
The benefit of compression elastic element is by this way, and the length of the Flexible element that the roller 24 of given diameter can be involved in is much larger than the situation of unpressed Flexible element.Therefore, a large amount of Flexible elements will take less space, perhaps reach the space of few 90%, thus make storage more effectively and/or transport more cheap.
Once need described Flexible element, it can be launched from described roller, make it restore to uncompressed state, and then according to such as, mattress/seat base or other pad or the length needed for plate cut.
Above-mentioned example is using coil spring as elastic element.But, other elastic element can be used, the spring of such as other type, as long as material layer separates at the compression direction of elastic element.
Simultaneously; the feature of the present invention paid close attention in above-mentioned specification sheets is considered to particular importance, it should be understood that the combination of the characteristic mentioned in the claimed any patent characteristic of applicant or literary composition; and/or display is in the example shown, no matter whether lay special stress on thereon.
