The Problem of Graphic Mounting "Butterfly Mounting"

Let me tell you something! Butterfly binding is a kind of binding, and it is also a kind of exquisite binding. If you make a single copy, you usually use double-sided tape (there is a large roll of double-sided tape). Double-sided tape will leak after a long time, but this time period is very long, and there is white latex! Apply a thin layer with a special glue machine, and then check the watch. There are actually many kinds! I think my typing is too slow! Please forgive me. Simply put, there are two ways: one is solid mode, the other is liquid mode, and the liquid mode is better.
