Spreader roll

What is a spreader roll?

The spreader roll is a roll that is most often assembled on a fixed, arched axle, the surface of which consists of steel bushings. Finbow rolls have a rubber and metal coupler between the bushings that transmits power from one bushing to another, keeping the impurities and moisture safely outside the roll.

The efficiency of the spreader roll is based on the curvature of the roll, as well as the roll’s correct angle and speed relative to the path of the paper.

By adjusting the surface properties, the steel-coated rolls are suitable for all positions in a paper machine. A correct grooving on the surface gives characteristics to the rolls of a fast machine that cannot be achieved on a smooth surface.

Fly roll

What is a fly roll?

A fly roll is a roll designed to control the transverse tension of a super calender line. The purpose of the fly roll is to keep the paper path in a straight transverse direction, which keeps the paper’s quality constant. 

The secret of the Finbow fly roll’s longevity lies in matching the roll’s properties (speed, temperature, moisture) to the operating conditions. Another important factor is the mechanical structure of the roll, which must be strong enough in relation to the diameter and length of the roll.

Finbow's innovative rubber coupling transmits power from one bushing to another and keeps out impurities.
