Abstract: A yarn color placement system for a tufting machine including a series of different color yarns being fed to the needles of the tufting machine by yarn feed mechanisms. A backing material is fed through the tufting machine at an increased stitch rate as the needles are shifted according to the programmed pattern steps. A series of level cut loop loopers or hooks engage and pick loops of yarns from the needles, with the clips of the level cut loop loopers or hooks being selectively actuated to form cut pile tufts, while the remaining loops of yarns can be back-robbed so as to be hidden from view in the finished patterned tufted article.

Abstract: A tufting machine has a needle bar for carrying a plurality of needles for reciprocating into and out of a base material. A sliding needle bar shift mechanism may shift the needle bar laterally according to a pattern. The needle bar is mounted for reciprocation and for lateral movement relative to the direction of reciprocation by a drive system including a first directional drive component having a foot secured to a respective push rod of the tufting machine and a second directional drive component connected to the shift mechanism. The first and second drive components will connect to the needle bar through linear bearings or bushings so that the motion of the needle bar in multiple different directions is controlled while permitting greater machine operating and needle bar shifting speeds.

Abstract: The present invention provides a cam follower bracket that is used in conjunction with textile tufting machines. Typically, the present invention is used with shifting tufting machines used to produce carpet and rugs. The cam follower bracket utilizes a floating lug design that self-regulates the amount of pressure that the cam follower bearings apply against the shifter block of the tufting machine. Because the bracket is able to self-regulate the pressure, the bracket generally lasts longer and does not need to be periodically monitored and/or tightened. Therefore, less user interaction is required and less machine downtime is needed when operating a tufting machine utilizing a bracket according to the present invention in comparison with known cam follower brackets.

Abstract: Processes for tufting substrate or primary carpet backing using conventional double needle bars but in which the needles may be shifted less than a full gauge. Processes of the present invention may employ a conventional double needle bar tufting machine to which is added means for shifting or indexing the hook bar laterally to the machine direction of the substrate being tufted. Timing of shifting of the hook bar may be coordinated with timing of shifting of the needle bar and advance of the substrate through the machine to allow piles to be tufted into the substrate at any desired lateral position with respect to previously tufted piles. The invention creates additional pile color pattern alternatives and eliminates repetitive patterns otherwise necessitated by full gauge shifting. Elimination of repeat color sequences reduces matching color sequences on adjoining edges of adjacent carpet tiles made from such substrate which otherwise accentuate or highlight the seams between carpet tiles.
