In our coater, it is controlled by the metering gap between two coater rollers with the same rotation direction and the metering roller, forming the coating on the coating roller with the required thickness.

That is, the speed at which one of the measuring rolls does not rotate is zero, and the part of the measuring roll becomes a comma shape, also known as a comma scraper. Our coating thickness can be adjusted by changing the distance between the comma scraper and the coating roller.

In our special roll coating form, when the operation is not correct, the position of the knife edge deviates from the working position, the coating parameters and the slurry parameters are not within a certain range, and there may be vertical strip defects.

Due to the process, there is no need for drying equipment, low energy consumption: no solvent (hot melt adhesive is 100% solid composition) pollution-free, the operator will not contact a large amount of formaldehyde because of cleaning residual glue.

The design principle and operation precautions of the coating machine are introduced here, and we must have a certain understanding of the equipment design and operation principle of the coating machine through the introduction of this article. We sincerely welcome you to choose our products here.
