Abstract: Methods for fabrication of articles, in particular knitted articles, using computer-controlled machines. A 3D model of the article is characterized by a 3D polygonal mesh defining a surface of the 3D model. A streamline is drawn on the 3D model, and used to define a set of isolines over the surface described by the 3D polygonal mesh. The isolines are quantized into equidistant points along their respective lengths and a cut line traversing each of the isolines is defined. Courses are defined by connecting quantization points of the isolines based on knitting rules to produce a 2D knitting map containing apexes. Apex attraction may be performed on a first portion of the 2D knitting map by decreasing a spatial distance between respective ones of the apexes. The 2D knitting map is subsequently converted to knitting instructions for a computer-controlled knitting machine.

Abstract: A method for reducing the occurrence of float threads on the surface of a machine-knitted fabric. Beginning with an initial programmed pattern describing yarn used at each stitch in a knitting pattern, the present method identifies stitches that will create float threads, sorts the identified float threads, giving priority to those float threads that would most limit stretch in a knitted garment, taking into account factors such as float thread length, location in a garment and yarn stretch. Then, in order of the sorted float thread list, the present method assigns additional yarns of the same characteristics as the original yarns to available yarn feeds to minimize the eventual creation of float threads in the knitted fabric. Multiple passes are made through the programmed pattern until no additional floats can be mitigated, or until a predetermined number of passes has been completed.
