Profile of the Company

The NERA s.r.o.has got more than forty-years-experience in development and structural designing of special textile machines, which have found application also in other industries as cutting into pieces, cutting of margins and drawing-in of glass vlies, mats and fabrics. Special machines have proven well also in paper-making industry.

Cutting and winding machines, based on drawing documentation and know-how of the NERA s.r.o. have been used successfully by the manufacturers of vlies combined with the Spudbond materials. Similarly the single-purpose cutting machines for felt longitudinal cutting, designed for the manufacturers of felt, painting rollers and squeegees. Because of their high reliability they became popular not only in the Czech Republic, but also in Germany and Turkey. Considerable achievements have been reached on the field of laminating of textile and other technological material to be used in car-making, furniture, shoe and synthetic material industry as well as in manufacture of non-woven textile materials. Laminating textile for car seat upholstery are produced in the LL-100 continually laminating line for the AUTO ŠKODA in the Czech Republic and they comply with the ISO standards.

On the field of AGRAR vlies a continuous binding line was developed successfully for the purposes of agriculture, which binds the materials of 15 g/m2 and more within a width and length required. The special cutting machines for cutting into pieces, cutting off and automatic drawing-in of glass vlies and fabrics have proven very well, as they are equipped with the tools, which almost do not need any edge-sharpening.

SSVI winding and cutting machine

SSVI winding and cutting machine




Winding and cutting machines of the series SS VI are designed for longitudinal cutting and winding of text materials and paper. Machine structure includes a bridge crane with loading capacity of 500 kg, which facilitates insertion of input and paper materials (rolls) and removal of processed products from the machine.

A structure is very heavy and rigid, and it provides very smooth operation (winding and cutting) at high speed up to 250 m/min. The materials can be processed up to the width of 3.200 mm (optionally even 4.200 mm). All functions needed for winding and cutting can be pre-programmed.

VLIES CUTTING MACHINE

VLIES CUTTING MACHINE




The SSVII cutting machine is used for longitudinal cutting of vlies into strips. Optionally the machine can be equipped with automatic vlies feeding unit, or it can be supplied withaut it. An advantage of work with the SSVII is that the cutting disks cut onlythe vlies weave and do not cut further libres in vlies.

Working width - 1500 m in standard design, or adjusted to customer's requirements
The minimum width of strip is 35 mm. The cut stripes are divided by 5 mm
The maximum number of cutting knives on a single shaft (at working width of 1500 mm) is 40
Cutting speed is continually adjusted the range from 0 up to 12m/min.
Carriage drawing-in is adjustable up to 240 mm
The machine is driven by 3 electric motor, having an output of 2.85 kW
The maximum input is about 3 kW. Weight of about 500 kg.

SSIX winding and cutting machine
WINDING AND CUTTING MACHINES SSX

WINDING AND CUTTING MACHINES SSX




Winding and cutting machines SSX series serve for cutting and winding of textile materials (fabrics) and paper. The textile and paper input material move to and from the machine by means of a bridge crane which moves along the machine on a crane railing. The crane rails are part of the machine.

A robust design of the machine secures a smooth winding and cutting at high speed (up to 250 m/min.) with the windth of imput material up to 4200 mm (165 inch). All functions necessary for high-quality winding and cutting are programmable in advance.

Technical characteristics:

  • Working width (input material): max. 4.200 mm
  • Material polypropylene bat (polyester, polyamid):
    • Spundbond 15 - 150 g/m3
    • Paper 40 - 150 g/m3
  • Input material:
    • roll unwound max. 800 mm (31,5 inch)
    • roll cut max. 800 mm (31,5 inch)
  • Tubes clamped pneumatically min. inner diameter 76 mm (3 inch).
  • On customer's request it is possible to supplz winding rod for tubes with inner diameter of 40 mm and lager (classical clamping).
  • Machine speed: max. 250 m/min.
  • Min. width of cut strips is 50 mm (2 inch)
