Web transport arrangement

摘要

A web transport arrangement is devised for transporting a web material along a web path. The web material is supplied by a variable feed mechanism to a processing mechanism for processing the web. The web material while being metered by the feed mechanism is maintained by the mechanism under a low tension although the web may be maintained under a high tension during subsequent processing operations. A control circuit automatically compares the feed rate of the web through the low tension feed area to the rate of the processing mechanism operative on the web within the processing area and provides for any necessary modification of the infeed rate in order to synchronize them.
