Bookbinding machinery is specialized equipment used in post-processing operations for printed materials. In manufacturing, it is used for binding technical documents, manuals, catalogs, and quality record documents. This includes saddle stitching machines, perfect binding machines, case binding machines, folding machines, cutting machines, hole punching machines, and ring binding machines. Unlike printing machinery, these are post-processing dedicated devices that automate folding, binding, cutting, and finishing of printed sheets. Excluding simple office bookbinding machines, this targets industrial bookbinding equipment capable of continuous operation. This machinery group contributes to improving efficiency in binding quality control documents and technical specifications.
