  • the stretchable thermoplastic web which is supplied to the belt has a width that is narrower than the belt and wider than the openings therein so as to completely cover the work areas while leaving the apertures along the edge of the belt exposed. These apertures cooperate with registration maintaining devices at the subsequent web processing stations in the apparatus so that the work areas, and thus the designs printed on the belt at the work areas, are maintained in registration at each of the processing stations.
  • the belt transports the web to the first of a series of processing stations at which one side of the web is treated, such as for example, by a silk screening process or by an embossing process. Subsequently, the belt I sequentially transports the web to the remaining processing stations at which other printing or embossing operations are performed in registration with the printing or embossing performed at the prior stations. Registration between operations at each of the processing stations is maintained by a Series of sprocket rollers operatively connected with the various web treatment means, which sprocket rollers include sprockets received in the apertures on the belt so as to accurately position the belt at the processing stations.
