[0002] In the carton manufacturing industry, the clamping partition plays various roles such as external load bearing, mutual separation of articles, and stabilization of products. Generally, after being slotted or die-stamped, qualified parts are arranged, and then inserted by manual or machine, becoming a three-dimensional inner lining structure. When the product itself exceeds a certain size and is arranged in the carton and contacts the inner wall of the carton, the folded ears of the paper clamping partition edge need to be attached, that is, folded and attached to the staggered clamping partition, which ensures the overall structure of the clamping partition while the folded ears do not occupy space. However, the paperboard itself does not have adhesion, and mutual attachment must rely on external force, that is, an edge attaching process is added. Common edge attaching processes include stapler buckling, ultrasonic embedding, glue bonding, and hot melt glue bonding. These processes are mostly complicated, expensive, and low in production efficiency, which does not meet the concept of streamlining. Therefore, how to attach the folded ears without relying on other objects or how to eliminate the edge attaching process is an important problem to be solved.
