This invention in one embodiment comprises a cylindrical rod with a rotating, removable loop head inserted into the center of the top end of the rod. The loop head is inserted into a vertical hole drilled into the top end of the rod, wherein the loop head is able to rotate in the hole. The loop head has a plurality of outwardly radially extending circumferential loops that receive wire for bending and weaving into the Viking Knit. Preferably, the rod also has an anchor hole, drilled diagonally through the rod near its top end, for receiving and securing a wire. Preferably, the rod also has a conical wire wrap attachment at the bottom of the rod for making wired end caps to cover or enclose the finished Viking Knit Weave. In another embodiment, this invention comprises a hollow cone with a rotating, removable loop head inserted in either or both ends of the cone.

Material Blend With Patterned Fabric
20180119321 · 2018-05-03 ·

A blended fabric having a patterned color includes a first portion comprised of cotton and a second portion comprised of polyester. A dye that has a strong affinity for cotton and a slight affinity for polyester is applied to the fabric. The dye gives the cotton portion a deep black color and applies a light gray color to the polyester portion. A combination of deep black cotton and light gray polyester combines to provide the patterned color of the blended fabric. The blended fabric may be comprised of a larger percentage of cotton than polyester that is spun into a single filament yarn that is then knitted into a Jersey Knit styled fabric, a looped knit terry fabric, or a fleece fabric. Further, the present invention comprises a blended fabric whereby dye absorption by the cotton and not by the polyester create darker and lighter patterns within the blended fabric.

Methods for fabrication of articles from three-dimensional models

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.
