Abstract

The invention discloses a nail-free seamless paper corner protector frame formed in one step. The nail-free seamless paper corner protector frame formed in one step comprises paperboards and is of a multilayer structure formed by winding the paperboards; the paperboards are coated with adhesives, and every two adjacent paperboards are staggered and adhere to each other through the adhesives; the paperboards are provided with indentations. According to the nail-free seamless paper corner protector frame formed in one step, punching, indenting, corner folding and adhesive applying are carried out on bobbin paper in advance, then the bobbin paper winds around a die circle by circle and gets pressed and bonded for forming a whole body, every two adjacent layers of the bobbin paper can be bonded and connected through the adhesives such as glue because the punching positions of every two adjacent layers of the bobbin paper are staggered, and therefore the purposes of turning corners and avoiding nailing connection at joints can be realized, and various shortcomings of existing products can be completely overcome.

Description

【Technical field】 [0001] The invention mainly relates to a nail-free and seamless one-time forming paper corner protection frame and a manufacturing method thereof. 【Background technique】 [0002] Paper corner protectors are widely used in product packaging in various industries because of their low cost, ease of use, resistance to extrusion and impact during use, and recyclable recycling, which is harmless to the environment. For paper corner frames used in the packaging industry, the industry’s practice is to produce a straight paper corner frame first, and then according to the size of the paper corner frame to be formed, punch holes and bend at the corner, and then make holes on the seams and joints. The position is stamped with stud molding. This will produce two subsequent processes of punching and nailing, and cause work-related accidents when workers operate punching machines and nailing machines. The customer also reported that the paper corner frame with nails wi...
