    摘要: A tufting machine for selectively forming tufts of yarns, including different color or type yarns, for forming patterned tufted articles such as carpets. A series of needles are reciprocated into and out of a backing material being fed through the tufting machine and are engaged by a series of gauge parts so as to pick-up loops of yarns from the needles. The gauge parts will be selectively controlled by activators to extend or retract the gauge parts to positions or elevations sufficient to pick-up or not pick-up loops of yarns from the needles. The feeding of the yarns to the needles further will be controlled to back-rob yarns not picked-up by the gauge parts, while the backing feed will be controlled to enable formation of tufts at an increased rate over the pattern stitch rate for the pattern of the tufted article being formed.

    摘要: A tufting machine (100) comprises a needle bar (10) shiftable in a needle bar longitudinal direction (L), a plurality of needles (12) being provided on the needle bar (10) following each other in the needle bar longitudinal direction (L), each needle (12) being individually selectable for carrying out a stitch and thereby generating a pile on a backing fabric, further comprising such a yarn threading that, on the needle bar (10), groups (G) of the needles (12) following each other in the needle bar longitudinal direction (L) and comprising a predetermined number of needles (12) are generated, the needles (12) of each group (G) having yarns of different properties threaded therethrough, the number of yarns of different properties associated with each group (G) being less than the number needles (12) within each group (G), such that, within each group (G), at least two needles (12) have yarns of the same property threaded therethrough.

    摘要: A method for embroidering three-dimensional workpieces (2) uses an embroidery machine (100) with at least one embroidery head (101) for embroidering and at least one embroidery frame (1) for positioning the workpiece (2). The workpiece (2) is moved by means of the embroidery frame (1) by at least two angles (Θ, μ, ω) in relation to at least two axes (X, Y, Z), which are in relation to the movement axis of the embroidery head (101) positioned to introduce at least one stitch of embroidery into the workpiece (2).
