Double Side Circular Knitting Machine
FEATURES
Double side Circular Knitting Machine are single jersey machines with a ‘dial’ that houses an extra set of needles positioned horizontally adjacent to the vertical cylinder needles. This extra set of needles allows the production of fabrics that are twice as thick as single jersey fabrics. Typical examples include interlock-based structures for underwear/base layer garments and 1 × 1 rib fabrics for leggings and outerwear products. Much finer yarns can be used, as single yarns do not present a problem for Double side Circular Knitting Machine knitted fabrics.
YARN&SCOPE
The yarn fed to the needles in order to form the fabric must be conveyed along a predetermined path from the spool to the knitting zone. The various motions along this path guide the yarn (thread guides), adjust the yarn tension (yarn tensing devices), and check for eventual yarn breaks on Double side Circular Knitting Machine
DETAILS
The technical parameter is fundamental to the classification of Double side Circular Knitting Machine. The gauge is the spacing of the needles, and refers to the number of needles per inch. This unit of measure is indicated with a capital E.
Double side Circular Knitting Machine now available from different manufacturers are offered in a vast range of gauge sizes. The vast range of gauges meets all knitting needs. Obviously, the most common models are those with middle gauge sizes.
This parameter describes the size of the working area. On Double side Circular Knitting Machine, the width is the operating length of beds as measured from the first to the last groove, and is normally expressed in centimeters. On circular machines, the width is the bed diameter measured in inches. The diameter is measured on two opposite needles. Large-diameter circular machines can have a width of 60 inches; however, the most common width is 30 inches. Medium-diameter circular machines feature a width of about 15 inches, and the small-diameter models are about 3 inches in width.
In knitting machine technology, the basic system is the set of mechanical components that move the needles and allow the formation of the loop. The output rate of a machine is determined by the number of systems it incorporates, as every system corresponds to a lifting or lowering movement of the needles, and therefore, to the formation of a course.
Double side Circular Knitting Machine rotate in a single direction, and the various systems are distributed along the bed circumference. By increasing the diameter of the machine, it is then possible to increase the number of systems and therefore the number of courses inserted per each revolution.
Today, large-diameter circular machines are available with a number of diameters and systems per inch. For example, simple constructions such as the jersey stitch can have up to 180 systems.
The yarn is taken down from the spool arranged on a special holder, called a creel (if placed beside Double side Circular Knitting Machine), or a rack (if placed above it). The yarn is then guided into the knitting zone through the thread guide, which is typically a small plate with a steel eyelet for holding the yarn. In order to obtain particular designs such as intarsia and effects, the machines are equipped with special thread guides.
