| 摘要 |
The invention relates to a device for bending a flat, round disc element (12; 14), especially for forming a widened gap (54) between two adjacent, facing disc elements (12, 14), which are to be glued together. The device (16; 18) comprises a first means (20) for contact with a first portion of the disc element (12; 14), a second means (28) for contact with a second portion of the disc element (12; 14). The second, radially outer means (28) is axially movable relative to the first means (20). A vacuum source is disposed to bend the radially outer portion of the disc element as the second means (28) is retracted. |
