Rotary scissors NR-18 for cutting of veneer sheets

• The knife does not require periodic sharpening of the cutting edge, the edge itself has to be changed once every 1 - 1,5 years or after cutting of 35000 - 50000 m3 of veneer;
• The scissors are driven by conventional asynchronous electric motors;
• Availability of an automatic mode of operation without participation of an operator;
• Rate of the veneer sheet placement in the mode of cutting and stacking in the range of 0,5 -2,3 m/sec is adjusted from a control panel by the line operator;
• The scissors can be mounted into any line for wood peeling, cuttings and stacking of veneer.

The rotary scissors NR 18-3 are characterized by simplicity of design, operation and service, by rapid response, absence of frictional brakes and high accuracy of cutting.
Productivity of the scissors during nonstop feeding of veneer 1600 mm long and 1,5 mm thick is 2 m/sec - 17 m3 / hour.
Operating conditions of the rotary scissors meet requirements of the clause 3.1 (Storage conditions), stipulated in GOST 15150-69 – operation in the enclosed heated or cooled and ventilated industrial premises.
