Long decorative material with embossing in register with pattern and rolling method and device therefor

A rolling method for a long decorative material with an embossing in register with a pattern, comprising:

• a feeding step of feeding a layered raw material to be rolled into oppositely rolling rollers by a feeding device, the layered raw material comprising a transparent plastic layer and a printed plastic layer printed with repeating unit patterns;
• and
• a rolling step of hot rolling an embossing on the transparent plastic layer;
• wherein in the feeding step, the transparent plastic layer is located at one side of the printed plastic layer where the repeating unit patterns are printed, the transparent plastic layer is adjacent to an embossing roller of the oppositely rolling rollers, and an embossed pattern disposed around an outer cylinder of the embossing roller corresponds to a pattern of one unit pattern on the printed plastic layer, wherein a longitudinal deviation of the embossing is adjusted in the rolling step, an adjusting step comprises:
• detecting the longitudinal deviation between the pattern on the printed plastic layer and the embossed pattern on the embossing roller by sensing a position of a preset part in each unit pattern on the already stretched printed plastic layer prior to coupling the transparent plastic layer and the printed plastic layer and after the feeding device, and detecting a position of a corresponding part directly on the embossing roller corresponding to the preset part prior to embossing, and
• adjusting a feeding tension of the printed plastic layer according to the longitudinal deviation, so as to adjust a stretching length of the printed plastic layer between the feeding roller of the printed plastic layer in the feeding step and the oppositely rolling rollers in the rolling step before rolling and thereby embossing, so that the longitudinal deviation in rolling is reduced until the embossed pattern is in register with the pattern on the printed plastic layer during rolling, and the embossing hot-rolled on the transparent plastic layer is longitudinally in register with the pattern on the printed plastic layer,
• wherein the registering of the embossing on the transparent plastic layer and the pattern on the printed plastic layer is realized during the rolling by the embossing roller;
• wherein the method further comprises the step of controlling the heating temperature of the oppositely rolling rollers by a control device, the control device controlling a hot medium flowing into the oppositely rolling rollers.
