The invention provides a circular knitting machine for prompting a knitting machine status instantaneously based on a cloth surface status of a fabric, comprising a needle cylinder, a camera module capable of photographing the fabric during doffing, an information processing unit, and an encoder. A camera lens of the camera module does not rotate with the needle cylinder, and a shooting timing of the camera lens is controlled by photographing signals. The information processing unit receives image data generated by the camera module, and compares the images, when there is a difference between the two consecutive image data on a same vertical line, a knitting machine status is prompted. The encoder generates pulse signals when the needle cylinder rotates, the encoder outputs the pulse signals to the camera module or the information processing unit, and the receiver counts the pulse signals to generate the photographing signals.

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.

The present disclosure relates to a knitting method and device based on a knitting pattern in which front, left-sleeve, right-sleeve and rear-shoulder pieces are integrally connected. The method includes: collecting a knitting pattern graphic or instruction; receiving pattern information sent by a data collection module to determine the knitting type, and defining the knitting start position, the knitting direction, the knitting point position and the stitching path of different knitting types; wherein, a control module controls a driving module such that a knitting needle knits in a V-shaped path, a horizontal path or a vertical path; and when the knitting needle moves to a panel border position or a reversing position, a state monitoring module sends information to the control module, and the driving module adjusts the knitting action until the knitting operation on a target knitting panel is completed.
