Abstract
An improved conveying device for conveying a thin web through a station in both directions with the desired registry characterized by a supply device for storing a reel of the thin web, a guiding device for guiding the thin web through the station and a take up or receiving device for rewinding the web with the take up or receiving device and the driving means being controlled so that the take up device does not apply any tension to the web at the station. In order to determine the exact amount of the web passing through the station a meter or measuring device is utilized and to ensure proper alignment of the web, the guiding means includes rollers continually holding the edge of the web against a lateral guide member. Due to the control and the use of the meter device, the web may be moved back and forth through the station to allow processing laterally offset portions of the web and maintain the registry between the various laterally offset portions.
