Oscillators
In the demanding conditions of the paper and board industry, every tool and machine component matters.
30 years at the forefront of oscillation expertise
Oscillation refers to a back-and-forth motion that can be utilized in various functions — for example, to ensure the smooth movement of a doctor blade beam in paper and board machines. This helps the blade wear evenly and keeps the roll clean from pulp. In collaboration with leading paper and board machine manufacturers, we have developed a superior range of oscillators that perform reliably in demanding conditions.
The oscillators feature a compact structure that integrates both the cylinder and the valve controlling its movement. Each unit is designed, engineered, and manufactured by the skilled hands of Pimatic’s dedicated professionals.
