Abstract
A method is provided for manufacturing flooring planks including a plastic base and an image plastic layer. The method includes a feeding step of feeding a plastic layer into oppositely rolling rollers; and a rolling step of hot rolling an embossing on the plastic layer. A feeding tension of the plastic layer is adjusted according to a longitudinal deviation between the embossing and the pattern in the rolling step. A device includes a first feeding device, an oppositely rolling rollers control device, a detecting device, and a tension controller disposed on the first feeding device. The method, the device and the long plastic layer with the embossing in register with the pattern processed use the method, implement the embossing rolled on the plastic layer in register with the pattern on the plastic layer and have high production efficiency, low cost and less energy consumption.
