Abstract (en)
[origin: ES8203243A1] Metal billets trapped in the billet container of an indirect extrusion press are removed by indirect extrusion in the reverse direction until the billet size is reduced sufficiently for the residue to be expelled bodily from the container. The stem used to support the container-closing plug constitutes, or is replaced by a stem for effecting the reverse indirect extrusion.
