Method of applying a cover layer to a structured base layer
First Claim
1. A method of applying a cover layer to a base layer which has a structured surface, said method comprising moving said base layer at a first feed rate (v);
- moving the cover layer at a second feed rate which matches said first feed rate; and
applying the cover layer to the base layer via a guide;
wherein in order to achieve a desired synchronization said method further comprises prior to the application of the cover layer to the base layer the steps of;
determining the position of a structure on the structured surface of the base layer via a sensor;
utilizing positional information from the position determination of the structure to trigger a laser control signal, and controlling a laser in response to said control signal to create a recess in said cover layer in a position corresponding to the position of said structure on said base layer, whereby said structure is received in said recess when said cover layer is applied to said base layer.

Abstract
A method for applying a cover layer (1) to a base layer (2) which is provided with structuring (3) determined, for example, by printed conductors. The base layer (2) is moved continuously at a feed rate (v) in continuous operation. A guide (4) constructed as a rotatable body, brings the cover layer (1) to the matching feed rate (v) and applies the cover to the base layer (2). To optimize the application of the cover layer (1) to the structure (3) on the base layer (2), and in particular to prevent inaccuracies in the correlation between the cover layer (1) and the base layer (2) while at the same time permitting increased flexibility in manufacturing, the position of the structuring (3) is determined first by a non-contact sensor (5) immediately upstream of the guide (4). Then a signal for a laser (6) is triggered by a control unit (9). Depending on the position of the structuring (3), a recess is then created in the cover layer (1) by the laser (6), and the recess is thereafter made to correspond to the structuring (3).
