Embodiment Construction
[0027] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0028] Such as Figure 1 to Figure 4 Shown, a kind of intermittent positive and negative coating process is characterized in that comprising the following steps:
[0029] A: Loading, put the substrate to be coated on the unwinding unit 1.
[0030] B: feeding traction, the base material on the unwinding unit 1 is pulled out by the feeding traction device 2 .
[0031] C: the front side is intermittently coated, and the base material is connected between the front coating roller 31 and the first guide rubber roller 32 on the front coating unit 3 from the discharge end of the feeding traction device 2, and the front coating roller 31 is coated Apply the coating solution, and then control the front coating roller 31 and the first guide glue roller 32 on the front coating unit 3 to reciprocate and move away to apply the coating solution on the subst...

Description
【Technical field】 [0001] The invention relates to a coating or process and a coating machine. The process and the coating machine can be applied to the field of coating or printing, in particular to an intermittent front and back coating process and a coating machine. 【Background technique】 [0002] Due to actual needs, it is usually coated on the front and back sides of the substrate (such as laser film), and the coating area on each side needs to have a certain interval. The existing front and back coating process is relatively complicated, which leads to complex results of the coating machine, low work efficiency, and low accuracy of intermittent coating, resulting in low yield. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a simple process, high coating precision intermittent front and back coating process, another purpose is to provide a simple structure, high work efficiency, intermit...
