A web transport apparatus having an active support structure defining an active web transport path and a storage support structure defining a web storage path parallel to the active path. In use, the apparatus is juxtaposed with a treatment device so that the active path extends through the active zone of the treatment device. A sequence of semi-continuous webs may be treated by feeding each web along the active path while the next web is being threaded along the storage path, and shifting the next web laterally from the storage path to the active path upon exhaustion of the web being fed along the active path. The treatment device can remain operative while the storage path is being threaded. |
