Paper making automatic pneumatic felt stretcher correcter guider tensioner
Felt corrector It is used to correct the deviation when the felt and wire of paper machine deviates from the normal running track.
Pneumatic felt and wire automatic corrector is composed of pulse sensor and pneumatic actuator.
Working principle
When the net or blanket deviates, the baffle deviates from the middle position, and the pulse sensor converts the offset signal into a pressure signal to pressurize or depressurize the air in the left pneumatic tire of the actuator, and the corrector moves to the left or right, so as to achieve the purpose of automatic correction.
The structural pulse sensor is composed of baffle, detector head, support, connecting pipe, etc.
The detector head is essentially a high sensitivity three position four-way rotary valve. When the net or blanket deviates, the baffle swings, and the inlet and outlet direction of the air path is changed by the detection head. The compressed air is sent to the corrugated pneumatic tire of the actuator to push the corrector.
The forms of pneumatic actuators manufactured by different foreign manufacturers are different, but their basic structures are similar.
The displacement of automatic correction is 60 ~ 70mm, which can meet the needs of paper machines with width less than 3200mm.

FAQ
1. Why is it important for press felts to be centered on the machine?
To completely cover the sheet width to ensure uniform water removal in the press nips. Also, to keep the felts from running off the front or back of the machine.
2. What is the basic principle of fabric guiding?
The basic principle of fabric guiding is that the felt moves or "steers" toward the roll end that it contacts first.
3. By what mechanism does the movement of the guide palm cause the autoguide to move?
The guide palm movement closes or opens a bleed air valve, which increases or decreases the air supply pressure to an air bag which moves the autoguide end of the guide roll.
