RETAINING DEVICE AND METHOD FOR RETAINING A FLAT WORKPIECE

摘要

The invention relates to a retaining device and method for retaining a flat workpiece (1), comprising at least two clamping devices (2) for clamping a respective outer edge or a surface of the flat workpiece (1), and a movement device (3, 4, 5) for moving at least one of the clamping devices (2). At least one of the clamping devices (2) has at least one elastic element (6), which is configured to be stretched with a stretching of the flat workpiece (1) by moving the movement device (3, 4), such that, during the stretching, the elastic element (6) has a contact region between the flat workpiece (1) and the elastic element (6), wherein the elastic element (6) contacts the flat workpiece (1) at the start of the stretching and clamps at each position that is in contact at the start of the stretching.
