1. The molding unit with pre - piercing unit consists of:
   • Filling chambers FS - 2;
   • Feeding machine BST;
   • Canvas - forming machine V - 21;
   • Carding machine R - 12;
   • Needle punch machine NL 9/S;
   • Edge trimmers KS;
   • Winder SH;
2. The double piercing unit consists of:
   • Winder AW;
   • Needle punch machine NL 36;
   • Needle punch machine NL 42;
   • Winder SH;
3. The reject machine consists of;
   • Winder AR;
   • BST rejection device;
   • Edge opener RO;

In addition to these units, there are also all the necessary units for the operation of lines: pneumatic transport, loading chambers, dispensers - mixers, lubricants, scutching sections, etc.

The V21/R12 unit combines mechanical carding with aerodynamic web formation, which makes it possible to obtain web uniformity without thickening, approximately the same strength in the longitudinal and transverse directions, limited shrinkage in width and, accordingly, significantly reduce raw material consumption. The high quality of the canvas is achieved by careful sevenfold loosening of the fibers with a self - cleaning effect and random three - dimensional orientation of the individual fibers in the canvas.

With a working mixture consisting of 50% polypropylene fibers 1.3 dtex, L = 35 - 40 mm. And 50% polyester fibers 3.3 dtex, L = 35 - 40 mm, the plant capacity will be 140 - 180 kg/h. With a web weight of 400 - 600 g/m2 and a width of 2.2 meters, the efficiency of the installation is 90% .

• The needle punching process is carried out in 2 stages:
• pre - piercing by machine NL 9/S;
• final piercing on machines NL 36 and NL 42;

The needle punchers are synchronized with the V21/R12.

Needle - punching machines are mounted on rubber - metal supports, that is, they do not require laying foundations. Fully balanced eccentric mechanisms and a rigid box - shaped frame provide high stability and vibration - free operation at high lifting frequencies of 1000 or more lifts per minute.

Detectors are mounted in the line to detect metal objects and to remove broken needles.

The equipment can produce needle - punched materials weighing from 100 to 600 grams/m2 using fibers from different materials in different proportions.

The equipment is in excellent condition and can be tested and run at any time. If necessary, photos of the equipment can be sent to you.
