    • A process is described for trans-laminating an image-carrying sheet from a first laminated product, comprising the image-carrying sheet, an adhesive layer and a release sheet, to a second laminated product, comprising the image-carrying sheet, the adhesive layer and an ultimate support sheet. The process comprises the steps of:(i) temporarily adhering at least a leading edge portion of the image carrying sheet (12) of the first laminated product (10) to a surface (20) of a support member (22);(ii) temporarily adhering a leading edge portion of the ultimate support sheet (34) to the surface (20) of the support member (22) at a location adjacent the image-carrying sheet (12);(iii) separating the release sheet (14) from the image-carrying sheet (12) while the image-carrying sheet (12) remains adhered to the surface (20) of the support member (22), with the adhesive layer (16) facing upwardly;(iv) simultaneously or subsequently moving the support member (22), with the image-carrying sheet (12) adhered thereto, together with the ultimate support sheet (34), between a pair of rollers (28, 30) thereby to press the ultimate support sheet (34) downwardly against the image carrying sheet (12) to form the second laminated product (38), the leading edges of the image carrying sheet (12) and the ultimate support sheet (34) being substantially parallel to the axes of rotation of said rollers (28,30); and(v) thereafter releasing the second laminated product (38) from the surface of the support member (22).The process achieves the translamination without causing folds or stretches to occur in the product.
    • 描述了用于将包含图像载体片,粘合剂层和剥离片的第一层压产品的图像载体片层压到第二层压产品的方法,第二层压产品包括图像载体片,粘合剂层 和最终的支持表。 该方法包括以下步骤:(i)将第一层压产品(10)的图像承载片(12)的至少前缘部分暂时粘附到支撑构件(22)的表面(20)上; (ii)在与所述图像载体片(12)相邻的位置处临时将所述极限支撑片(34)的前缘部分粘附到所述支撑构件(22)的表面(20)上; (ⅲ)当图像载体片(12)保持粘附到支撑构件(22)的表面(20)上时,将剥离片(14)与图像载体片(12)分离, )面向上 (iv)同时或随后使所述支撑构件(22)与所述极限支撑片(34)一起在所述一对辊(28,30)之间与所述图像承载片(12)一起移动,从而将所述支撑构件 最终支撑片(34)向下抵靠图像承载片(12)以形成第二叠层产品(38),图像承载片(12)和最终支撑片(34)的前缘基本上平行于轴 所述辊(28,30)的旋转; 和(v)之后从支撑构件(22)的表面释放第二叠层产品(38)。 该过程实现了翻译,而不会在产品中产生折叠或拉伸。
