DEVICE FOR APPLYING A PRODUCT FILM TO A SUPPORT

摘要

Device for applying a film to a support, comprising: a) an impregnation roller intended to collect the product to be applied and which is provided with a plurality of microdimples in its external surface; b) a scrubbing member (4) which is in tangential contact with the impregnation roller (3) and which leaves on said roller only the product contained in the microdimples; c) a transport roller (5) which is in contact with the impregnation roller (3) and to which adheres on its surface the product contained in the microdimples, in the form of droplets (21); and d) a squeezer roller (6) which presses the support (7) against the transport roller (5) causing the transfer of the product droplets (4) from the transport roller (5) to the support and simultaneously the expansion of said droplets, thereby producing a uniform film of product on the support (7).
