Tufting machine and method of tufting
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.

TUFTING MACHINE AND METHOD OF TUFTING
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 actuators 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 can be controlled in conjunction with the movement of the gauge parts, while the backing feed can also be controlled, to enable formation of tufts of yarns at an increased rate over the pattern stitch rate for the pattern of the tufted article being formed.

TUFTING TOOL MODULE
A tufting tool module (10) for a tufting machine is provided. The tufting tool module comprises a plurality of tufting tools (20). The tufting tools have a head portion and a securing portion. The securing portion of each tufting tool is casted in a base block (12). The securing portions of each tufting tool is provided with at least two cut outs (26, 28) located inside the base block. By providing such cut outs it is possible to reduce the lateral pressure differences between the different tufting tools of the tufting tool module during casting of the base block. This is because the cast material, such as zinc, is allowed to move more freely within the cast during casting of the base block. Furthermore, the cut outs will during the cooling phase of the metal, e.g. zinc, control and stabilize the shrinkage so the tufting tools will not be dislocated. In other words, dislocation of the tufting tools during the casting process can hereby be reduced or eliminated. The result is a tufting tool module with improved tolerances.

TUFTING TOOL WITH INSERT
A tufting tool (20) is provided. The tufting tool can be adapted to be used in a tufting machine. The tufting tool is formed by a first material (22). The tufting tool comprises an insert of a second material (24), where the second material is harder than the first material. The insert is formed by a cavity in the first material filled with the second, melted, material filling said cavity. Hereby a tufting tool with an insert can be made in a robust and efficient manner.
