摘要： The method of the present invention provides a way to make rolls of high shear strength pressure sensitive adhesive tapes with a transparent to the core appearance in a relatively short time and without the need to subject the rolls to additional method steps. Moreover, the present invention achieves such transparent to the core appearance by sufficiently wetting-out the adhesive on the tape backing to remove microscopic air bubbles entrapped within the harder and less deformable high shear strength adhesive layers. The method comprises a rewinding method and is characterized by the use of a pack roll during rewinding to provide a sufficiently high contact pressure to the non-adhesive side of the tape substantially at the application point of the tape to the tape roll. In one aspect, a sufficient contact pressure is provided by the pack roll so that the pressure sensitive adhesive tape rolls are made with a transparent to the core appearance at the time of the rewinding step. In another aspect, the method further includes the step of aging the tape roll after the rewinding step is complete for allowing the tape roll to become transparent to the core after the rewinding step.
摘要翻译：本发明的方法提供了一种在相当短的时间内制造具有对芯外观透明的高剪切强度压敏粘合带的辊的方法，并且不需要使辊进行附加的方法步骤。此外，本发明通过充分润湿胶带背衬上的粘合剂来实现对芯外观的透明度，以去除夹在较硬且较不易变形的高剪切强度粘合剂层内的微小气泡。该方法包括重绕方法，其特征在于在重绕期间使用包装卷，以在带的非粘合侧基本上在带的施加点处向带卷提供足够高的接触压力。在一个方面，由包装辊提供足够的接触压力，使得压敏胶带卷在再卷步骤时对芯的外观进行透明化。另一方面，该方法还包括在倒带步骤完成之后使卷带老化的步骤，以便在卷绕步骤之后使带卷变得透明。
