    • Apparatus for splicing a replacement web (r2) to a moving web (r1) comprises a guide (G) for guiding the moving web along a predetermined path. A cutter (10') severs a portion of the replacement web (r2) to establish the leading edge thereof; and a splicing station is positioned in the path of movement of the moving web (r1) for splicing the leading edge of the replacement web (r2) to the moving web (r1) while the latter is moving.
      The splicing station, which is constructed and arranged to establish a lap joint between the leading edge of the replacement web (r2) and the moving web (r1), comprises a delivery device (H) that includes a splice strip (n) having adhesive on one surface, a device for positioning the strip (n) in a direction perpendicular to the direction of the moving web (r1), and a device for moving the replacement web (r2) in a direction perpendicular to the direction of the strip (n) and into engagement with the adhesive surface of the strip (n) in such a way that about half the width of the strip (n) is covered by the leading edge of the replacement web (r2) which adheres to the strip (n), and the other half of the strip (n) is uncovered exposing the adhesive. Finally, a device is provided for moving the strip (n) and the replacement web (r2) adhered thereto relative to the moving web (r1) such that the exposed adhesive on the surface of the strip (n) engages the moving web (r1) which is thereby adhered to the strip (n).
    • 用于将替换纸幅(r2)拼接到移动纸幅(r1)的装置包括用于沿着预定路径引导移动纸幅的引导件(G)。 切割器(10')切断替换卷筒纸(r2)的一部分以建立其前缘; 并且拼接台被定位在移动卷筒纸(r1)的运动路径中,用于将替换卷筒纸(r2)的前缘与后者移动时相接合。 构造和布置成在替换纤维网(r2)的前缘和移动纤维网(r1)之间建立搭接接头的拼接台包括输送装置(H),其包括具有粘合剂的接合片(n) 在一个表面上,用于沿垂直于移动幅材(r1)的方向的方向定位条带(n)的装置,以及用于沿垂直于条带方向移动替换纸卷(r2)的装置( n)并且以条带(n)的宽度的大约一半被粘附到条带(n)的替换网(r2)的前边缘覆盖的方式与条带(n)的粘合剂表面接合 ),另外一半的条带(n)被露出,露出粘合剂。 最后,提供一种用于相对于移动的网(r1)移动粘附到其上的条带(n)和替换网(r2)的装置,使得带(n)表面上的暴露的粘合剂与移动的网(r1)接合 ),从而粘附到条带(n)上。
