    • A method allows for rapid manufacture of relatively thick adhesive coatings using a continuous process, where a single thin coating is continuously converted into a single thicker adhesive laminate. An exemplary process includes the steps of: (1) producing a web having a first surface with an adhesive layer and a second surface with a release liner; (2) slitting the web longitudinally into a first section and a second section, each section having a first surface with an adhesive layer and a second surface with a release liner; (3) laminating a backing film to the adhesive layer of the first section; (4) removing the release liner of the laminate of step (3) exposing the adhesive layer of the first section; (5) positioning the laminate of step (4) and the second section so the exposed adhesive layer of the laminate of step (4) faces the adhesive layer of the second section; and (6) laminating the second section to the laminate of step (4), wherein the adhesive layer of the laminate of step (4) is combined with the adhesive layer of the second section. The resultant laminate of this exemplary process has one surface having a backing film, one surface having a release liner, and an inner area having an adhesive layer.
    • 一种方法允许使用连续方法快速制造相对厚的粘合剂涂层,其中单个薄涂层被连续地转换成单个较厚的粘合剂层压体。 示例性方法包括以下步骤:(1)制备具有带有粘合剂层的第一表面和具有剥离衬垫的第二表面的网; (2)将幅材纵向切割成第一部分和第二部分,每个部分具有带有粘合剂层的第一表面和具有剥离衬垫的第二表面; (3)将背衬膜层压到第一部分的粘合剂层上; (4)去除暴露第一部分的粘合剂层的步骤(3)的层压体的剥离衬垫; (5)将步骤(4)和第二部分的层叠体定位,使步骤(4)的层压体的暴露的粘合剂层面向第二部分的粘合剂层; 和(6)将第二部分层合到步骤(4)的层压体中,其中步骤(4)的层压体的粘合剂层与第二部分的粘合剂层组合。 该示例性方法的所得层压体具有一个具有背衬膜的表面,一个具有剥离衬垫的表面和具有粘合剂层的内部区域。
