The packaging materials applied to cigarette packets at present are basically provided with laser pictures and texts (laser holographic pictures and texts), and the laser pictures and texts are formed by mould pressing of a laser holographic picture and text mould pressing device. The laser holographic image-text molding device generally comprises a plate roller and a compression roller, wherein the plate roller comprises a molding working plate and a plate roller body, and the molding working plate is arranged on the plate roller body. When the laser holographic pictures and texts are molded, the molding material passes through the space between the molding working plate and the compression roller, the plate roller and the molding working plate heat the molding material, so that the molding surface of the molding material reaches the molding working temperature (the molding working temperature means that the molding working plate can press the laser holographic pictures and texts on the molding material at the temperature), meanwhile, the plate roller and the compression roller apply pressure on the molding material, and the molding working plate presses the laser holographic pictures and texts on the molding material. The plate roller continuously rotates, so that the die pressing working plate continuously presses the laser holographic pictures and texts on the die pressing material. Because the die-pressing working plate (usually a nickel plate) made by electroforming is a flat plate, when the die-pressing working plate is installed on the plate roller, two ends of the die-pressing working plate can leave a seam on the plate roller, therefore, when the laser holographic images and texts are pressed, plate seams corresponding to the seam (the plate seams refer to the gaps between two adjacent laser holographic images and texts on the die-pressing material, and the laser holographic images and texts are not pressed on the gaps) are inevitably generated on the die-pressing material, one plate seam is generated every time the plate roller rotates for one circle, which has great adverse effect on the subsequent procedures, for example, the plate seams are partially cut off, which wastes time and materials; for another example, when the embossing material is subsequently printed, a large amount of waste products are generated without dealing with the plate seam problem.
