Kettle machine is a piece of equipment used to join the outermost open loops on parts of knitwear (socks, stockings, etc.). The process of connecting loops is called kettle. This method of stitching parts is more practical and aesthetic than a hand-made seam.

Working principle

To fasten the edges of the product, the kettle machine is equipped with a needle conveyor (the so-called fontura). The edges of the parts to be joined are put on the needles of the conveyor (tokol) (one loop per one tokol). The needle carries out reciprocating movements along the grooves of the fontura tocols. Getting into the loops, the needle passes the thread through them, which connects the edges of the knitted parts.

Kettle equipment classification

In accordance with the number of threads that are involved in the formation of loops, knitting machines are:

• Single thread. Used for finishing the edges of knitwear uppers (processing collars, sides, pockets) and for knitting parts of hosiery.
• Two-thread. Used for knitting stockings, socks, tights and so on.
• Three-thread. Finishing the edges of parts to prevent fraying.

Seams produced by knitting machines,should be invisible and elastic. This is achieved by the correct selection of knitting equipment, which must correspond to the class of the knitting machine. The easiest way to choose is to select according to the density of knitwear. For this, the number of loop rows per unit of length is counted. Their number will correspond to the class of the kettle machine.

More often, knitting (that is, working on a knitting machine) is carried out on equipment whose class is higher than the class of the knitting machine used. This is due to the fact that the fiber removed from the knitting equipment is subject to some shrinkage, and for easy putting on of loops on the tokol of the knitting machine, the distance between the latter should be equal to the interval of the loop step. If this condition is not met, it is necessary to stretch the canvas or increase the gap between tokols.

Kettelnaya machine is classified depending on the method of formation of stitches, the nature of the movement of the conveyor and the design of the main mechanism. In addition, the needles of these machines (straight, curved) and the movements of the fontura (continuous, periodic) are different. Putting on loops on tokols is done manually, and the machine automatically combines, trims, cleans and processes the seam.

Kettle machine manufacturers

The main manufacturers on the sewing equipment market are HAGUE (England), CONTI COMLETT (Italy), RMS (Turkey), KMS (Turkey).

Thisequipment differs in purpose, that is, it is used in industry or in everyday life, as well as in class, drive (manual, electric) and, accordingly, price.

Overview of HAGUE models

• Hague 280 H is a manual chain-stitch machine used for joining knitted fabrics. When knitting necks and inlays, the class of knitting equipment is necessarily taken into account, since each loop of the part is put on the needle of the connecting machine. When sewing shoulder and side seams, products from knitting machines of any class can be used.
• Hague 280 E is a 5th grade electric kettle stitcher, like the previous model, sews chain single stitches.
• Hague 290 CE is a class 3 electric kettle equipment. It is used to connect the details of clothing, which is connected on machines of the third class. The operations performed are similar to those of the models described above.
• Hague 280 FE is a class 7 electronic knitting machine, pictured below, that performs single-thread chain stitches and is used to assemble parts made on class 7 knitters.

Overview of CONTI COMPLETT models

99-K/DD. This model of a knitting machine connects knitted parts with double-thread chain stitches. Such a connection is beneficial both from an aesthetic and practical point of view. In addition, all Conti Complett models use a special stitch formation system, which allows you to increase productivity to the maximum (up to1,400 stitches per minute) even when working with such "heavy" raw materials as nylon, wool, lurex and others

Fronture movements are carried out clockwise, the needle is located outside the frontura, and the looper is inside. The diameter of the ring is eighteen inches (i.e. 460 mm). The possible class of the car is from the third to the twenty-second

Review of RMS Models

Kettelnaya machine RMS PROKET is used for stitching knitted parts with single or double thread chain stitches. The possible class of the car is from the third to the eighteenth. The front moves counterclockwise. The needle is on the inside of the front and the looper is on the outside.

KMS models

KMS 1420 is a knitting machine that provides elastic stitching with a capacity of one thousand two hundred stitches per minute. The parts are connected with a single-thread chain seam. Can be used to stitch any type of knitwear.
