Apparatus and method for associating cut sheet sections with a moving carrier web

摘要

Apparatus and a method for providing cut pieces from a first moving web and associating the cut pieces with a second, faster-moving carrier web. A vacuum roll is provided and cooperates with an adjacent cutter roll to enable transverse cuts to be made in the first web material. A vacuum manifold is provided and contacts the end wall surface of the vacuum roll to provide vacuum to apertures provided in the outer periphery of the vacuum roll. The vacuum roll and the vacuum manifold have spiral-like ports and slots to provide communication between a source of vacuum and the periphery of the vacuum roll at predetermined points in the path of rotation of the vacuum roll. The point of application of the vacuum to the leading edge of the first web is shifted rearwardly over the peripheral surface of the vacuum roll to correspond substantially with the slower rectilinear speed of the first web material, and thereby avoid the imposition of excessive tension to the first web material so that it is not permanently elongated before it is applied to the carrier web.
