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 for automatically altering the stitch rate of a tufting machine of the type having a main shaft for reciprocating at a prescribed rate of reciprocation a plurality of needles for inserting yarns carried by the needles through a back material as backing material rolls progressively feed the backing material longitudinally through said tufting machine and across the path of reciprocation of said needles so that said needles respectively produce successive tufts in successive transverse portions of said backing material, comprising:
Process for automatically altering the parameters of tufting of a tufting machine of the type having a main shaft for reciprocating a plurality of needles and a backing material which is fed at a prescribed rate across the path of reciprocation of said needles so that the needles successively insert tufts of yarns to prescribed depths in said backing material as the backing material is fed along a longitudinal path, comprising the steps of:
The process defined 8 including means for detecting the quantity of backing material which has been tufted by the needles at a prescribed stitch rate and for stopping the tufting action after a prescribed amount of tufted backing material has been produced.
A tufting machine having a motor driven main shaft, at least one needle bar carrying a plurality of needles, yarn feed means for supplying yarn to said needles, a bedrail, backing feed means for moving backing material across said bedrail, and means for reciprocating said needle bar to drive said needles into and out of the backing material as it is moved over said bedrail, comprising:
A process for automatically controlling the parameters of operation of a tufting machine having a motor driven main shaft, a least one needle bar carrying a plurality of needles, yarn feed means, a bedrail, backing feed means, a yarn feed servomotor, a cloth feed servomotor, computing means, operation interface means, encoding means, and a plurality of indexers comprising the steps of:
A tufting machine assembly for automatically altering the pile height of a tufting machine of the type having a main shaft for reciprocating at a prescribed rate of reciprocation a plurality of needles for inserting yarns carried by needles through a backing material as the backing material rolls progressively feed the backing material longitudinally through said tufting machine and across a bedrail and across the path of reciprocation of said needles so that the bedrail prescribes the position of the backing material as the backing material passes longitudinally through said tufting machine;
