1. A device for manufacturing a pleated curtain, comprising:
elongate pleating means configured to form a first fold with a predetermined pleat height in the curtain by folding the curtain round a long side of the pleating means along a fold line;
clamping means configured to clamp a pleat portion of the curtain on either side of the first fold over the predetermined pleat height at least along a clamping line parallel to the fold line and at a predetermined pleat depth distance from the fold line, such that the pleat portion, as seen in a cross-sectional plane perpendicular to the fold line, forms a U-shaped loop; and
control means for controlling the pleating means and the clamping means;
wherein the control means are configured to move the pleating means and/or the clamping means relative to each other such that, as seen in said cross-sectional plane, the pleating means are arranged from a position inside the loop to a position adjacently of the loop, while the clamping means clamp the pleat portion, such that a remaining portion of the curtain differing from the pleat portion is folded round an outer end of the clamping means and at least a second fold round the pleating means arranged adjacently of the loop is formed adjacently of and parallel to the first fold.
