Estimating the term…
A tufting machine is provided with separate motors which drive the main drive shaft, control the feed of the backing material and control the bedrail height. A computer is electrically connected to these motors and to the yarn feed controls. The software indicates patterns to be produced, informing the computer to control the number of stitches per inch of backing, the weight of face yarn per square yard, the pile height, the amount of yarn fed to the needles and the linear length of carpeting produced. The computer also dictates the schedule by which prescribed lengths of additional patterns are produced by the tufting machine and can control a number of such tufting machines. When the pile height is to be changed, the computer automatically controls the main motors for rocking the main shaft, to reciprocate the needles while controlling the yarn feed controls and the motor to the bedrail.
A tufting machine assembly of the type having reciprocating needles for inserting yarns carried by the needles through a backing material as the backing material is progressively fed through the tufting machine and across the path of reciprocation of said needles and so that said needles produce tufts in said backing material, the improvement comprising:
The process of tufting wherein needles insert yarns carried by the needles through a backing material as the backing material is progressively fed through a tufting machine and across the path of reciprocation of the needles so that the needles produce tufts in the backing material, comprising the steps of:
