Abstract (en)
[origin: DE102005057424A1] The coreless process produces a tube (1) from a sheet (5) by placing it in a die made in two halves (3, 4) and closing them up to produce a tube with a slit. The deformation takes place in the half-dies, and the edges (6, 7) of the sheet are prevented from sliding forward as the die is closed up to form the slit tube.
