Manufacturing of small film strips

摘要

The present invention relates to methods and apparatuses for forming films. In particular, the present invention relates to the formation of films on a substrate via the use of individual pumps to deposit individual wet film products onto a substrate. A method of forming film products includes: providing a reservoir housing a film forming matrix, pumps in association with the reservoir, and orifices; feeding the wet film forming matrix from the reservoir to the pumps; dispensing the film forming matrix from each of the pumps through an orifice; and depositing wet film products onto a substrate. An apparatus for forming film strips includes: (a) a reservoir for housing a film forming matrix; (b) pumps associated with the reservoir; (c) a plurality of orifices, with each orifice being associated with a pump; (d) a substrate; and (e) a means for moving the substrate through the apparatus.

1. A method of forming a plurality of individual film products, comprising the steps of:
(a) providing a reservoir housing a film forming matrix; (b) providing a plurality of individual volumetric pumps connected to said reservoir; (c) providing a manifold comprising a plurality of orifices, wherein said manifold comprises a first side and a second side, wherein each orifice extends from said first side of said manifold to said second side of said manifold, wherein each orifice is in fluid communication on said first side of said manifold with one of said individual volumetric pumps which is its own individual volumetric pump; (d) feeding said film forming matrix from said reservoir to said individual volumetric pumps; and thereafter (e) dispensing a predetermined amount of said film forming matrix from each of said individual volumetric pumps through said orifice in fluid communication therewith from said first side of said manifold to said second side of said manifold; and thereafter (f) depositing a plurality of individual wet film products directly onto a substrate from each of said orifices.
