Abstract
An apparatus and a method for embossing micro- and/or nanostructures in an embossing material.
Claims38
1-17. (canceled)
An apparatus for embossing micro- and/or nanostructures in an embossing material, said apparatus comprising:
- a structured stamp having a stamp face with micro- and/or nanostructures,
- an embossing element for transferring an embossing force to the embossing material,
- a control device for controlling contact of the structured stamp with the embossing material and removal of the structured stamp from the embossing material, said removal controlled in a targeted manner, and
- at least one clamping bar for holding the structured stamp, said at least one clamping bar movable along a removal curve.
1 more element
A method for embossing micro- and/or nanostructures in an embossing material, said method comprising:
- embossing the micro- and/or nanostructures in the embossing material by contacting a structured stamp with the embossing material, wherein a mobile embossing element transfers an embossing force to the structured stamp held by at least one clamping bar, said structured stamp having a stamp face with micro- and/or nanostructures,
- removing the structured stamp from the embossing material in a targeted manner, and
- moving the at least one clamping bar along a removal curve.
A stamp system comprising:
- a structured stamp having a stamp face with micro- and/or nanostructures for embossing micro- and/or nanostructures in an embossing material,
- a carrier connected to the structured stamp,
- an embossing element for transferring an embossing force to an embossing material,
- wherein the structured stamp and the carrier are configured elastically such that the structured stamp and the carrier are deformable by the embossing element, and
- at least one clamping bar for holding the structured stamp, said at least one clamping bar moveable along a removal curve.
