Title:
WEB SPEED METERING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2003062108
Kind Code:
A3
Abstract:
A web speed metering device to which a moving web (12) is fed at a constant web infeed speed and from which the web (12) periodically exits at a different speed that is correlated with the timing of a downstream operation performed on the moving web (12). The metering device is a rotatable member (24) that is non-axisymmetric and that has a cross-sectional shape having a centroid that is offset from the axis of rotation (26) of the rotatable member (24) to change the web output speed as the web exits from the metering device. The metering device allows a web (12) to be fed to a downstream cutting device (10) and enables the web output speed to be regulated so that the web (12) 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.
