Description

Technical Field

[0001] This utility model relates to the field of book production equipment technology, and in particular to a device for seamless gold-edged book blocks. Background Technology

[0002] In the book production process, adding gold trim to the three sides of the book block (forehead, foot, and back) is a common technique to enhance the book's aesthetics and artistic value.

[0003] Traditional gold-leafing techniques typically involve five steps: First, the book's edge is polished to make it smooth and flat, followed by gold-leafing to create a gold decoration at the book's edge. Second, the book's head is polished to make it smooth and flat, and then gold-leafing is performed again to create a gold decoration at the book's head. Next, the book's foot is polished to make it smooth and flat, and then gold-leafing is performed again to create a gold decoration at the book's foot. After that, the two corners of the book are cut to form rounded corners. Finally, the two rounded corners are polished to make them smooth and flat, and then gold-leafing is performed again to create a gold decoration at the two rounded corners.

[0004] However, while this traditional hot-pressing technique can achieve basic decorative effects, it has many shortcomings. Because the hot-pressing of the rounded corners is done separately from the hot-pressing of the forefoot, head, and foot, it not only leads to low efficiency but also easily results in noticeable seams at the junctions, severely affecting the overall aesthetics of the book. Furthermore, this technique often results in rounded corners that are not smooth and rounded enough, exhibiting obvious flaws and detracting from the book's appearance.
