2. Paper consumption: It must be determined according to the paper consumption specified in various models and specifications, and it cannot be excessive. Otherwise, the following disadvantages may be caused:
(1) the handle can't be pressed down, and the paper can't go in.
(2) The margin is not balanced, and paper edge curling is easy to occur.
(3) The square shaft is twisted, and the service life of the binding machine is shortened.
3. The principle of adjusting the paper margin is to determine the margin size according to the diameter of the tab.
The method is to adjust the scale with the adjusting screw (installed behind the binding machine) to achieve the purpose of margin.
The rules are: the diameter of the pull ring is large, the paper edge is large, the diameter of the pull ring is small, and the paper edge is small.
4, drilling operation method:
(1) Arrange the paper neatly, close to the positioning block, and feed the paper into the machine in parallel until it is in place.
② Hold the paper with your left hand, hold the handle with your right hand, press down until the blade penetrates the paper, and then lift the handle.
③ Take out the printing paper smoothly with both hands. If there is paper hanging, press the handle repeatedly, and then lift and take out the paper.
5, ring binding method:
According to the quantity of paper, choose different sizes of pull rings, slowly push the handle up until the pull ring opens, then insert the paper hole into the pull ring, slowly pull the handle back, and after all the pull ring teeth are inserted into the paper hole, pull the handle in place, tighten the pull ring opening, and the bound book will be installed.
Many customers do not know how to judge the quality of a binding machine when purchasing binding machines, nor can they start with binding machines of different categories and brands. Here, I would like to introduce some parameters that must be considered when purchasing a binding machine:
