Influence of Paper Machine Doctor Blades on Paper Quality

The performance of paper machine doctor blades directly affects paper quality and operational stability. A properly matched blade can stably remove attachments on the cylinder surface, ensuring even stress on the paper web, which helps improve paper flatness and gloss. If the blade material is too hard, fitting is uneven, or pressure is abnormal, it may cause surface scratches, uneven gloss, and even web breaks due to excessive local stress, increasing the break rate. High-quality blades clean thoroughly with gentle contact, ensuring smooth and flat paper, reducing break risks, and improving efficiency. Proper selection and standard use greatly enhance paper quality and reduce production loss.
