Method for producing a roll of membrane units

Abstract

The invention is directed to a method for producing a roll (1) or sheet of membrane units (2) for a membrane product (3) such as a lateral flow test from a roll (6) or sheet of membrane material (7), by means of a primary production arrangement (9), wherein the roll (6) or sheet of membrane material (7) is processed into a roll (1) or sheet of membrane units (2) in a primary processing routine, wherein in the primary processing routine, for generating the membrane units (2), a fluidic structure (11), in particular a hydrophobic structure, for defining fluid flow through the membrane material (7) is introduced into the membrane material (7) by means of a processing tool (12), wherein an evaluation routine is performed by means of an evaluation arrangement (15) comprising a sensor arrangement (16) and an evaluation control (17). It is proposed that in the evaluation routine, evaluation images (18) of the fluidic structures (11) of the membrane units (2) are generated by means of the sensor arrangement (16) and evaluation data (19) are generated by means of the evaluation control (17) and that the evaluation data (19) represent the deviation in predefined geometrical properties of the fluidic structure (11) in the respective evaluation image (18) with respect to the fluidic structure (11) in a reference image (21).
