VORRICHTUNG ZUM FOERDERN VON BAHNMATERIAL

摘要

In an apparatus for feeding a web, the web is continuously pulled from a reel by driven pairs of pinch rolls to create a loose storage loop from which the web is fed along a guide channel to a further pair of feed rolls, which when signalled passes material to a work station, under the influence of tensioning rolls acting on the web beyond the work station. Means are also provided for detecting and fullfilling the need for delivery of the web.
