    摘要: Where can bodies of sheet metal are welded between the welding rollers of a welding machine, the welding current is not applied to the welding rollers until the body is between the welding electrode rollers. In this way, the quality of the weld at the initial weld point is improved, and where intermediate wire electrodes are used, wire breaks are reliably prevented.

    摘要: According to the present invention, a method and an apparatus for rounding a sheet or plate blank in a rounding apparatus having rounding rolls is provided. A predetermined second part region of the blank is rounded after a predetermined first part region has been rounded. A feed direction of the blank for the rounding of the second part region is selected such that rounding in the second part region proceeds towards the previously rounded first part region.

    摘要: On a two-roll rounding machine, in addition to a compressively elastic guide roll and a compressively rigid rounding roll, one or more compressively elastic rolls are provided which have both a rounding function and a supporting function for the rounding roll. These additional rolls may also be supported by a back-up roll. The result is a rounding machine that has very good rounding characteristics even at small rounding diameters.
