Abstract: A web speed metering device to which a moving web is fed at a constant web infeed speed and from which the web periodically exits at a different speed that is correlated with the timing of a downstream operation performed on the moving web. The metering device is a rotatable member that is non-axisymmetric and that has a cross-sectional shape having a centroid that is offset from the axis of rotation of the rotatable member to change the web output speed as the web exits from the metering device. The metering device allows a web to be fed to a downstream cutting device and enables the web output speed to be regulated so that the web as it leaves the metering device can be cut transversely by a non-instantaneous cut that takes place over a predetermined machine-direction distance, such as a chevron-shaped cut.

Abstract: 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.
