Abstract

Claims (36)

1 . A tufting machine comprising:

at least one needle bar having a plurality of needles positioned therealong;

at least one yarn feed mechanism feeding yarns to the needles as the needles are reciprocated into and out of a backing;

a plurality of gauge parts positioned below the backing and movable in a direction of reciprocation toward and away from the needles as the needles are reciprocated into the backing;

wherein the gauge parts are moveable in an additional direction with respect to the path of travel of the needles between an operative position for enabling pick-up of loops of yarns from the needles and a no-sew position to substantially avoid pick-up of the loops of yarns; and

a control system including programming configured to control feeding of the yarns to the needles in coordination with movement of selected ones of the gauge parts in the additional direction with respect to the needles so as to selectively pick-up loops of yarns from the needles.

2 . The tufting machine of claim 1 , wherein the at least one needle bar comprises a pair of needle bars.

3 . The tufting machine of claim 2 , wherein each needle bar has a series of needles positioned therealong in a substantially in-line arrangement.

4 . The tufting machine of claim 2 , wherein each of the needle bars has a row of needles positioned therealong; and wherein the row of needles of an upstream one of the needle bars are staggered with respect to a row of needles of a downstream one of the needle bars.

5 . The tufting machine of claim 1 , wherein the plurality of needles are positioned along the at least one needle bar in a substantially in-line arrangement.

6 . The tufting machine of claim 1 , wherein the plurality of needles are positioned along the at least one needle bar in a staggered arrangement.

7 . The tufting machine of claim 1 , wherein the gauge parts comprise loopers, hooks, level cut loop loopers, or combinations thereof.

8 . The tufting machine of claim 1 , wherein the gauge parts include a body and a throat extending from the body; and wherein the movement of the gauge parts in the additional direction comprises pivoting the body of the gauge parts to move the throats of the gauge parts between the no-sew position and one or more operative positions for picking-up the loops of yarns from the needles.

9 . The tufting machine of claim 1 , further comprising a plurality of actuators coupled to the gauge parts; wherein the actuators are controlled by the control system to move the gauge parts between the no-sew position and one or more operative positions to selectively pick-up the loops of yarns from the needles.

10 . A tufting machine comprising:

a backing feed configured to feed a backing along a path of travel through a tufting zone of the tufting machine;

a plurality of needles located along the tufting zone;

wherein the needles are reciprocated into and out of the backing as the backing is fed through the tufting zone;

a plurality of gauge parts positioned below the backing;

wherein the gauge parts are movable in a direction of reciprocation toward and away from the needles as the needles are reciprocated into the backing and are moveable in an additional direction with respect to the reciprocation of the needles; and

a control system including programming configured to control feeding of yarns to the needles in coordination with selected movement of the gauge parts in the additional direction with respect to the needles between a lowered position at which the gauge parts are below a penetration depth of the needles, and one or more operative positions at which the gauge parts will pick-up loops of yarns from the needles.

11 . The tufting machine of claim 10 , wherein the needles are positioned in spaced series along at least one needle bar; and further comprising at least one shift mechanism configured to shift the at least one needle bar or the backing in a transverse direction with respect to the path of travel of the backing through the tufting zone.

12 . The tufting machine of claim 11 , wherein the control system further comprises programming configured to coordinate shifting of the at least one needle bar or the backing with the selective movement of the at least some gauge parts in the additional direction, and feeding of the yarns to the needles as the needles are reciprocated into and out of the backing such that when a loop of yarn is not picked-up by a gauge part, the yarn is pulled low or substantially withdrawn from the backing.

13 . The tufting machine of claim 10 , further comprising at least one needle bar; and wherein the needles are positioned along the at least one needle bar in spaced series in a substantially in-line arrangement.

14 . The tufting machine of claim 10 , further comprising a pair of needle bars spaced across the tufting zone; wherein each of the needle bars includes at least one row of needles mounted therealong; and wherein the needles of the at least one row of needles of an upstream one of the needle bars are staggered with respect to the needles of the at least one row of needles of a downstream one of the needle bars.

15 . The tufting machine of claim 10 , wherein at least some of the gauge parts are received within a module or holder mounted to a gauge bar; wherein the gauge parts are carried with the modules or holders to move the gauge parts in the direction of reciprocation toward and away from the needles and are moveable through the modules or holders in the additional direction.

16 . The tufting machine of claim 10 , further comprising a plurality of actuators coupled to the gauge parts; wherein the actuators are controllable by the control system to move selected gauge parts between their lowered and operative positions to pick-up the loops of yarns from the needles.

17 . The tufting machine of claim 16 , wherein the actuators are controllable by the control system in cooperation with the feeding of the yarns to the needles to selectively extend or retract the gauge parts along which a loop of yarn has been captured to form tufts of different pile heights.

18 . A method of forming a patterned tufted article, comprising:

feeding a backing along a path of travel through a tufting machine;

reciprocating a plurality of needles into and out of the backing;

moving one or more gauge parts of a plurality of gauge parts to a lowered position so that the one or more gauge parts will not pick up loops of yarns carried by the needles;

moving the gauge parts in a direction of reciprocation toward the needles as the needles are reciprocated into the backing such that the gauge parts that are in an extended position will pick up loops of yarns from the needles; and

pulling non-selected yarns substantially out of the backing or sufficiently low to an extent to enable the non-selected yarns to be held in the backing while substantially avoiding creation of undesired or unnecessary gaps or spaces between retained or face yarns of the patterned tufted article.

19 . The method of claim 18 , wherein moving the one or more gauge parts to the lowered position comprises selectively controlling one or more actuators coupled to the one or more gauge parts to retract the one or more gauge parts from their extended position to their lowered position.

20 . The method of claim 18 , further comprising raising or lowering selected gauge parts on which a loop of yarn is captured and controlling the yarn feed to form tufts of yarns having different pile heights.
