A shiftable backing feed and shiftable needle assembly is utilized with a tufting machine having reciprocating needles and gauge parts for seizing or cutting yarns wherein marginal step yarn placement techniques can be utilized in connection with a row of needles to minimize over-sewing needle positioning, and three axis shifting may be employed to optimize stitch locations in the backing fabric.

Advanced stitch placement with backing shifting

A method for automatedly inserting void stitches in the manufacture of pixel mapped patterns on tufting machines having an array of independent yarn feed devices feeding yarns to reciprocating needles employs an algorithm to determine if a stitch should have a void substituted for the stitch and then implemented.

Outline void pattern

A method is provided for the design and manufacture of tufted patterned textiles having selected yarn densities that may vary for different pattern palette colors and in different areas of a pattern.

Variable density tufting patterns

A shiftable backing feed is utilized with a tufting machine having reciprocating needles and gauge parts for seizing yarns at a plurality of fixed heights, wherein fabric support apparatus reciprocates in synchronization with the cycles of the needle bar to support the backing during penetration of the backing fabric yet allow backing shifts between stitches.

Multi height looper and backing shifter

A shiftable backing feed or shiftable needle assembly is utilized with a tufting machine having reciprocating needles and gauge parts for seizing or cutting yarns wherein yarn placement patterns can be utilized to tuft at different gauge densities while maintaining the same pattern sizes and appearance, and gauge parts are adapted for high density stitching.

Variable or multi-gauge cut pile tufting with backing shifting

A shiftable backing feed or shiftable needle assembly is utilized with a tufting machine having reciprocating needles and gauge parts for seizing or cutting yarns wherein yarn placement patterns can be utilized to tuft at different gauge densities while maintaining the same pattern sizes and appearance.

Variable or multi-gauge tufting with color placement and pattern scaling

A method is provided for optimizing the yarn consumption in patterned textiles by applying cell automata algorithms to bitmapped-type pattern designs including operator selected rules to influence the general appearance of the pattern design.
