Document Type and Number:
WIPO Patent Application WO2003061635
Kind Code:
A3
Abstract:
The present invention pertains to a method for producing products in web form in which a coating mass comprising one or more active-ingredients first is applied onto the surface of a transfer support web, subsequently the composite of transfer support web and coating is treated thermally, then an intermediate support material is applied onto the coating and finally the product in web form comprising the intermediate support material and the coating are separated from the transfer support web, wound up and stored. The transfer support web used thereby is performed as an endless loop. The transfer support web performed as an endless loop is recirculated to be applied again with the coating after its regeneration. The invention pertains also to a device suitable for performing the method.
