    • A method of applying a coating of hot melt polymeric material from a die to a substrate. Hot melt polymeric material is extruded through the die onto the peripheral surface of a rotating application roller to provide a coating layer along that peripheral surface. A substrate is conveyed past the peripheral surface of the application roller at an application interface to cause transfer of the first coating layer to the substrate and shearing and thinning of the coating layer because the substrate is conveyed faster than the peripheral speed of the application roller. The velocity of the peripheral surface and spacing between the die and the application interface along are selected to provide a time interval of at least 0.12 second for movement of portions of the coating layer from the die to the application interface, thereby affording relaxation and molecular reorientation of the hot melt polymeric material after the extruding step to facilitate shearing of the first coating layer at the application interface without causing ribbing or breaking of the coating layer.
    • 将热熔聚合物材料的涂层从模具施加到基底上的方法。 将热熔聚合物材料通过模具挤出到旋转施加辊的外围表面上,以沿着该外围表面提供涂层。 衬底在应用界面处被传送通过施加辊的外周表面,从而使第一涂层转移到衬底上,并且由于衬底的输送速度比施加辊的圆周速度更快,所以涂层的剪切和变薄。 选择周边表面的速度和模具与应用界面之间的间距,以提供至少0.12秒的时间间隔,用于将涂层的一部分从模具移动到施加界面,由此提供松弛和分子重新取向 的挤出步骤之后的热熔聚合物材料,以便于施加界面处的第一涂层的剪切,而不会引起涂层的破裂或破裂。
