  • Method and device for treating substrates
    Patent number: 11823931
    Abstract: A method for detaching a liquid lamella from a substrate edge is provided. A tear-off front is configured at at least one point of the liquid lamella. A width of the liquid lamella is then reduced by guiding the tear-off front along the substrate edge. Thus, the width of the liquid lamella prior to being torn off the substrate edge can be reduced by at least 50%, as compared to an original width of the liquid lamella.

  • METHOD AND DEVICE FOR TREATING SUBSTRATES
    Publication number: 20220148900
    Abstract: A device treats substrates with a liquid, which device has a conveying device by which the substrates can be conveyed in a conveying direction through a container containing a liquid. A weir has an edge over which the substrates can run and which, at least in sections, extends obliquely relative to the conveying direction of the substrates. The weir is used in the device for treating substrates with a liquid. The weir has at least one edge which extends obliquely at least in sections.

  • METHOD AND DEVICE FOR TREATING THE UNDERSIDE OF A SUBSTRATE
    Publication number: 20170330780
    Abstract: A method for treating the underside of a planar substrate with a treatment medium includes hydrophobizing the underside of the substrate, subsequently forming a protective liquid film on a top side of the substrate and then bringing the treatment medium into contact with the underside of the substrate. In the process, the protective liquid film protects the upper side of the substrate from any action or effect of the treatment medium and/or outgassing. A device for carrying out the method is also provided.
