Abstract:
1. Method for contacting of a sheet surface of a flexible sheet and a first contact surface of a first element, comprising the steps of: providing an anchor having an anchor surface for contacting the sheet surface, the anchor surface and the first contact surface of the first element having an adjustable first relative lateral position to each other; using a first contacting process to establish a first contacting stage of the method wherein at least a first part of the sheet surface is in contact with at least one of the anchor surface and the first contact surface; while in the first stage, determining a first lateral misalignment of the sheet surface with respect to at least one of the surfaces with which the sheet surface is in contact; confirming the first lateral misalignment by determining whether the first lateral misalignment exceeds a threshold; correcting the misalignment by establishing a second contacting stage of the method wherein a part of the sheet surface is in contact with the anchor surface, while no part of the sheet surface is in contact with the first contact surface, the second stage being established in such a manner that at all times between the first and second stages at least a part of the sheet surface is kept in contact with at least one of the anchor surface and the first contact surface; while in the second stage, adjusting the first relative lateral position to correct for the first lateral misalignment; and using a second contacting process to establish a third contacting stage of the method wherein the sheet surface is in contact with the first contact surface, the second contacting process being more accurate than the first contacting process.
