    • A cutting blade is mounted on an articulated arm for movement into location adjacent a new core and a free running span of the web on a winding machine. An adhesive strip is applied to the new core and then the core is rotated. A pressure roller on an opposite side of the web from the new core then urges the web into engagement with the surface of the new rotating core. As the adhesive strip rotates into contact with the moving web, it causes the web to be deflected into the knife which results in severing of the web. The leading edge of the severed web is maintained adhered to the adhesive strip so that no fold back of the leading edge occurs as the web continues to wind on the new core.
    • 切割刀片安装在铰接臂上,用于移动到邻近新芯的位置和卷绕机上幅材的自由运行跨度。 将粘合带施加到新的芯上,然后使芯旋转。 在幅材与新芯的相对侧上的压辊然后促使纸幅与新旋转芯的表面接合。 当粘合带旋转与移动的纤维网接触时,其导致纤维网被偏转到刀中,导致幅材的断裂。 切断的纤维网的前缘保持粘附到粘合剂条上,使得当纸幅继续卷绕在新的芯上时,不会发生前缘的折回。
