A method of producing a plurality of analytical test strips by using a reel-to-reel process, each analytical test strip comprising at least one first layer having at least one first electrode , at least one spacer layer and at least one second layer having at least one second electrode , the method comprising: i. providing at least one continuous first layer web , having disposed on a first side at least one first electrode layer , the first layer web having a first layer edge ; ii. continuously disposing, in at least one first lamination station , at least one continuous spacer layer web onto the first side of the first layer web , wherein the spacer layer web has a spacer layer edge , wherein the disposing is position-controlled in a master-slave fashion by using a position of the first layer edge as a master position and a position of the spacer layer edge as a slave position, wherein the disposing takes place such that the spacer layer edge is offset from the first layer edge and that, thereby, a portion of the first side of the first layer and a portion of the first electrode layer remain uncovered by the spacer layer web ; and iii. continuously disposing, in at least one second lamination station , at least one continuous second layer web onto the spacer layer web , the second layer web having disposed on a first side at least one second electrode layer , wherein the disposing is performed such that the second electrode layer faces the first layer web , wherein the second layer web has a second layer edge , wherein the disposing takes place such that the second layer edge is aligned with the first layer edge , and wherein the disposing is position-controlled in a master-slave fashion by using a position of the second layer edge as a slave position; wherein in the master-slave fashion the slave position is adapted according to the master position. i. providing at least one continuous first layer web , having disposed on a first side at least one first electrode layer , the first layer web having a first layer edge ; ii. continuously disposing, in at least one first lamination station , at least one continuous spacer layer web onto the first side of the first layer web , wherein the spacer layer web has a spacer layer edge , wherein the disposing is position-controlled in a master-slave fashion by using a position of the first layer edge as a master position and a position of the spacer layer edge as a slave position, wherein the disposing takes place such that the spacer layer edge is offset from the first layer edge and that, thereby, a portion of the first side of the first layer and a portion of the first electrode layer remain uncovered by the spacer layer web ; and iii. continuously disposing, in at least one second lamination station , at least one continuous second layer web onto the spacer layer web , the second layer web having disposed on a first side at least one second electrode layer , wherein the disposing is performed such that the second electrode layer faces the first layer web , wherein the second layer web has a second layer edge , wherein the disposing takes place such that the second layer edge is aligned with the first layer edge , and wherein the disposing is position-controlled in a master-slave fashion by using a position of the second layer edge as a slave position; <EOS>
