Description

Technical Field

[0001] This utility model belongs to the technical field of printing and packaging equipment, and specifically relates to a nailing device for pre-fixing. Background Technology

[0002] When binding notebooks, exercise books, etc., punching or gluing is required. In the existing technology, before punching or gluing, the loose pages and cover are simply stacked and then punched or glued. However, when punching or gluing, the loose pages and cover are easily misaligned when subjected to external force, which leads to insufficient binding accuracy and an increased scrap rate. Therefore, it is necessary to pre-bind the loose pages and cover before punching or gluing to prevent misalignment between the loose pages during binding. However, there is currently no equipment on the market suitable for pre-binding. Utility Model Content
