Embodiment Construction

[0038] exist figure 1 A double-layer triple rapier weaving machine 2 is shown, which is used to produce a double-layer carpet 4 which is particularly suitable for use as artificial turf. The carpet 4 is made of an upper spacer fabric 42 and a lower spacer fabric 44 which are separated after weaving by a yarn cutter 6 which cuts the pile extending between the two fabrics. Loom 2 also comprises reed 8, and reed 8 can be in figure 1 Move between the position shown in solid lines and the position shown in dashed lines. The loom 2 also comprises 16 heald frames 10 moved by an electric servomotor 40 such as the one disclosed in EP-A-1 489 208 . exist figure 1 In , only four servo motors 40 are shown for clarity. All servomotors are controlled by an electronic control unit 50 comprising computing means in the form of a microchip 52 and a memory 54 accessible by the microchip 52 .

[0039] Three sets of rapiers are used in the loom 2 , namely a top set 12 of rapiers, a middle set...

Abstract

This method, for simultaneously weaving on a loom two fabrics (42, 44) provided with piles (424, 444), comprises the steps of weaving an inner layer (FL2, FL4) and an outer layer (BL2, BL4) for each distance fabric, binding the inner and outer layers with connecting warp yarns (401 -404) extending between the inner and outer layers, weaving pile warp yarns (501, 502) between the distance fabrics, and cutting the pile yarns. During weaving, the inner and outer layers of each distance fabric are kept apart by respective lancet means (202, 204). Moreover, for each pick (P1 -P13) and for each connecting warp yarn (401 -404) and each pile warp yarn (501, 502), one selects on the basis of the information relating to the layer (BL2, FL2, BL4, FL4) in which said warp yarn has been interlaced in the previous pick, on the basis of the shedding pattern and amongst several predetermined positions, a position (A1 -A8, B1 -B12) to be taken by a shedding element (10) driving said warp yarn (401 -404, 501, 502) during said pick.

Description

technical field [0001] The invention relates to a method for weaving two spacer fabrics simultaneously. A spacer fabric is a fabric comprising two layers of woven yarns separated by an empty space. In some special cases, the space can be filled with different materials, such as granular materials. Such spacer fabrics are sometimes referred to as "three-dimensional structures" and are particularly suitable for use as artificial turf for sports fields. Background technique [0002] From WO-A-2007 / 116290 is known a woven artificial turf comprising pile yarns extending from a base layer at two respective heights. This artificial turf can be woven on a double carpet loom. During weaving, some pile loops are provided to help the pile stay upright. These loops provide the turf with less elasticity. [0003] On the other hand, BE-A-1007679 discloses a method for weaving two fabrics, each having an inner layer and an outer layer, the inner layer facing the other fabric during we...
