Description

Technical Field

[0001] The present application relates to the technical field of folding machines, and in particular to a folding knife installation device for folding machines. Background Art

[0002] Folding machines are modern printing equipment that came into being with the modern printing industry. Modern printing plants usually include three processing procedures: pre-press, printing, and post-press. The main carrier medium is paper. Due to the rise of packaging printing, other materials such as plastic, fabric, leather, metal surface, etc. are also on the rise, but paper still dominates the main carrier. Printing industry processing is usually divided into book, periodical, and newspaper processing and packaging processing. Folding machines can be mainly used to fold various sizes and thicknesses of paper within the design range. They are suitable for large-scale folding such as fast printing centers, production enterprises, official documents, and business letters.
