Definitions
- the invention relates to a device for producing voluminous fiber layers with a fiber portion that is predominantly oriented perpendicularly to the layer plane, according to the preamble of patent claim 1.
- the layers are mostly held together by sprayed-on dispersion binders or by thermoplastic binding fibers and in some cases also by processing in needling machines.
- needling a fiber portion is aligned in the vertical direction and at the same time the fiber fleece layer is compressed, so that the thickness and thus the thermal insulation capacity of the fabric obtained decreases considerably.
- the volume of the flat structure is maintained if the fiber layer consists of a crimp-shaped fiber web in which the fiber portion oriented in the direction perpendicular to the layer plane predominates.
- the nonwoven fabric is pressed into a toothing of a large drum for crimping or wrinkling and connected to a supporting fabric by application of a binder.
- CS-PS 87 556 a device is known in which a nonwoven fabric is alternately folded with the aid of a pivotable pair of knives and pressed into a backing fabric after application of an adhesive binder.
- a generic device for forming compressed folds of nonwoven from carding according to CS-OS 235 494 contains a needle drum, a plate and a body which form a gap into which a removal bar (chipper) protrudes. This then folds the nonwoven, respectively. the fibrous web wavy.
- the resulting structure must be solidified either by impregnation with a binder or by sticking to a base layer.
- the fiber layer can also be consolidated in a subsequent sewing process with or without binding threads.
- the fiber layers produced in such a device thus have a considerable proportion of fibers oriented perpendicular to the plane of the fabric, but must be consolidated mechanically or with the aid of binders because of a lack of cohesion.
- the invention has for its object to provide a device for producing voluminous fiber layer with a predominantly perpendicular to the layer plane oriented fiber portion.
- the device consists of a section for feeding a fiber layer such as fiber web, non-woven fabric, fiber ribbon or knitted fabric, a compression section for compressing and forming the fiber layer and a section for discharging the fiber layer.
- the feed section contains two walls inclined at an angle of 25 ° to 60 °, formed by a metal plate or a system of longitudinally arranged rods or tubes.
- the one wall of the feed section advantageously consists of a system of wires arranged in parallel and simultaneously forming a wall of the discharge section.
- the upsetting section expediently contains a forming element in the form of a strip which is provided with tips on its working surface and can be assigned to a compression strip which works synchronously with it.
- the forming element can be formed by a system of mandrels or wires held on a rotatable cylinder.
- the main advantage of the device according to the invention is that it enables the production of a voluminous fiber layer made of fibrous web, non-woven fabric, roving and flat textiles without a textile support base.
- the device consists of a feed section, an upsetting section and a discharge section.
- the feed section has two walls 6, 9 inclined relative to one another at an angle of approximately 60 ° and a chipper 2 with a needled working edge arranged in the gap opening and pivotable in the direction of the arrow.
- the upsetting section consists of a conveyor belt 3, one on the circumference longitudinally corrugated roller 7, the middle section of the wall 6 and a compression bar 5.
- the discharge section is formed by the conveyor belt 3 and a parallel upper boundary wall 6, which in this embodiment is designed as a bent section of the inclined wall 6.
- the fiber web fed to the device is processed in such a way that the chipper 2 and the compression strip 5 vibrate in synchronism with one another. If the vibrating chipper 2 is in the lower dead position, the then also curved arc-shaped compression strip 5 is pulled off the roller 7 and vice versa.
- the fiber web delivered directly from the card is inserted from above between the walls 6 and 9 and removed by the chipper 2 onto the conveyor belt 3 and formed there into a folded fiber layer 4 between the conveyor belt 3 and the wall 6.
- the meltable fiber layer 4 containing fibers is then conveyed into a hot air system 8 and solidified there.
- FIG. 2 differs from the device of FIG. 1 only in that the lower portion of the wall 9 follows the circular path of circumferential arcuate compression mandrels 18 and the wall 6 as a grate made of z. B. steel wires is formed, through which the held on the roller 7 compression mandrels 18 can pass.
- the fiber layer supplied (z. B. a transversely layered fleece) is detected by the compression mandrels 18 when slipping on the wall 9 and into which the conveyor belt 3, the hot air system 8 and the exit portion of the wall 6, respectively. of Rostes comprehensive discharge section of the device promoted.
- the connection of the structure in the longitudinal direction is increased by the currently vibrating compression bar 5 with puncture needles, which is aligned parallel to the conveyor belt 3 and carries out reciprocating movements in the direction of the arrow, the timing of which is coordinated with the number of compression mandrels 18 and the speed of the roller 7 is.
- the fiber pile supplied by the card containing 75% polyester cut fibers and 25% polypropylene binder fibers and having a basis weight of 10 g / m 2, is conveyed between walls 6 and 9 of the feed section of the device.
- the vibrating chopper 2 folds the fiber web on the conveyor belt 3 into the form of a fiber layer with an adjustable fold height, the folds being pressed together by the compression bar 5.
- the fiber layer is transported on the conveyor belt 3 into the hot air system 8 and solidified there.
- the textile fabric produced in this way has excellent compressive strength, recovery capacity even after prolonged exposure and good thermal insulation properties. It is suitable as a heat-insulating material or lining material for the upholstery industry.
- FIG. 3 shows a variant of the device shown in FIG. 1, which in its feed and compression section only has the chipper 2 - ie no compression strip.
- the movement of the fiber layer 4 is carried out here by the conveyor belt 3.
- the upsetting section of the variant according to FIG. 4 contains only the curved bar 5 without the chipper.
- the working surface of the compression bar 5 is provided with tooth-like projections 10. These serve to convert the relevant fiber sections into the position parallel to the plane of the fabric in order to solidify them in this direction.
- FIG. 8 shows a compression strip 5 (see also FIGS. 1 and 2), with puncture needles 11 arranged in an adjustable manner. Penetration of these needles into the fiber layer formed leads to better solidification of the structure in the horizontal direction.
- a thread system with a proportion of thermoplastic binding fibers is fed into the gaps of the chopper 2 at intervals of 10 mm under a mechanical tension of 0.1 N per thread.
- the individual puncture needles 12 are mounted so that they can move back and forth in holes in the compression bar 5, which is shown in FIG. 7.
- the needles 12 are coupled to a device, not shown, which gives them a movement synchronized with the movement of the compression bar 5. The synchronization These movements are carried out so that the needles are pushed out in the working position of the bar 5, while they are pushed into the holes by the fiber material when removing the bar 5.
- Fig. 8 shows a discharge section of the device, which consists of a pair of sieve conveyors 13, 3.
- the discharge section shown in Fig. 9 consists of the screen conveyor 3 and the lower portion of the wall 6, respectively. a metal plate.
- FIG. 10 shows the wall 6, the lower section of which fulfills the function of the discharge section and is formed from a system of wires arranged in parallel.
- the discharge section has a separate upper wall 14, which is formed by a system of parallel cooling tubes with cooling liquid flowing therein.
- the wall opens into a heated zone with a grid with holes or slots.
- the wall 6 consists of a system of wires, which is provided on its leading edge with a system of smooth needles 15 arranged in series and including the angle of 60 ° with the horizontal plane. These needles 15 are intended for removing the fiber layer from the puncture needles 11 when the compression strip 5 moves back.
- the wall 6 interacts with a series of smooth needles 16 held in a bar 17.
- the bar 17 is a back and forth from a device, not shown Movement issued so that the needles 16 in the lower end position of the bar pass through the wall 6 into the discharge or compression space.
- the back and forth movement of the bar 17 is synchronized with the similar movement of the compression bar 5 so that the needles 16 penetrate into the delivery space during the striking phase of the bar 5.
- the needles 16 thus perform the function of a counterhold.
