For cutting layers of fabrics in mass production, used cutting machines, mobile and stationary, as well as parubochaya press. In addition, use a number of mechanisms and tools to facilitate the implementation of other works.
Mobile cutting machine. Mobile machines are distinguished in two types: machine with vertical and circular knives.
Cutting machine with vertical knife ETM-2 (Fig. 156, a) are used for cutting flooring into separate parts (rough cuts) with the subsequent transfer them to the tape machine (precise cutting), or for precision cutting of individual parts (large size).
Machines are used for cutting fabrics in flooring height 130 - 150 mm.

Cutting machine with circular knife , ASGM-1 (Fig. 156, b) is used to clip of parts having simple configuration, and cut flooring, clothes, dress, lining and applied fabrics.
The machine is used for cutting fabrics in flooring height 50 - 70 mm.

Stationary cutting machines. These machines are also of two types: machine with band knives and parubochaya press, the dies, made in the form parts, are cut cut.
Stationary belt machine ZL-SW-1 (Fig. 157) is used to fine (final) cut of medium and small parts.

Tape machines are equipped with a fuse from the cut hands.
Stationary belt machine RL - treskina, based on the same structure as dvoskina and only belt knife covers three of the guide pulley instead of two. This gives you the opportunity to increase the working flight of the machine, therefore, efficiently cut large parts. Table treskino machine is located at the same height cutting tables, which creates favorable conditions for movement of the flooring.
The maximum height of the cut flooring fabrics - 120 cm cutting Speed of the knife is 20 m/s.

Stationary belt machine RLZ - chetyrehstennoy. Extended reach allows the machine to precisely carve out large parts cut. The machine is in the workplace. The machine is equipped with a variator for continuously variable adjustment of the cutting speed, devices for controlling the tension of a belt knife, and instant recovery in case of breakage (Fig. 158).

Parubochaya press used mainly in footwear industry for cutting parts from leather and fabrics. The press (Fig. 159) can be applied in the garment industry for cutting small parts. K, so, for example, include: the parts of mittens, women's accessories, collar shirts, small standardized parts of the butt of the upper clothes etc. This method of cutting ensures the accuracy of configuration details and high productivity. Presses have different drive: electric, pneumatic and hydraulic.
Cutting is a promising method of cutting and is widely used in overseas garment industry.
Vyrubkoi equipment for the purpose has the following groups:
light parubochaya press - cutting of small parts: collars, flaps, cuffs and other (odnoetajnaya);
average parubochaya press - cutting of large parts: shelves, sleeves and other odnoetajnaya (double and triple parts);
heavy parubochaya press - cutting of an entire set of items: shirts, trousers, etc. (flooring) - group cutting.
Currently, work is underway to find new methods of cutting fabrics without the use of existing cutting machines, which occupies a large production area and do not provide a high quality of cut due to the movement of the decks:
the electric-spark method of cutting, which is the use of high voltage currents to tissue destruction of the entire flooring line almalki;
cutting tissue using a laser beam. Experiments showed that the synthetic fiber of the line of cutting melted, and the tissue thickness up to 1 mm are cut at a speed of 10 - 60 m/min.
A device for applying nasechek on the details of the cut. This is a manual device, in which is mounted a knife; used to run nasechek on the details of woolen fabrics. The use of fixtures is as follows. Before you make nadziejko, knife raised to the upper position, then the platform down under the lower edge of the bundle of cloth and push on the handle is applied nadziejko details.
3ажимы. When cutting silk fabrics, with a large slide, used metal pins, made of thin wire, or clips for fastening tissue. The clip consists of two spring jaws connected by a hinge.
Hole punch. A hole punch is used for marking the locations of hair on the side strip, marking Darts on the details of the cut lining, patch pockets, etc. Work on the punch needle is rotating, receiving the motion from the electric motor. Needles are used with different thickness for different fabrics: needle diameter to 3 mm.
The hole punch set on the floor so the needle is over the puncture site. The machine turn on and when pressing the hand on the arm of the rotating needle (with motor) descends and pierces the fabric.
