The invention relates to a method for extruding curved extrusion products (7a, 7b), whereby the extruded profile is formed in a die that is located upstream of a crosshead (4) of an extrusion installation (1) and is subsequently curved or bent by the action of external forces. The extruded strand (7a, 7b) is taken up at the press outlet by a bearing surface (10) that supports the underside of the strand. Once a partial length of strand has been separated, said length is moved (10) from the press flow and is transported away by the bearing surface, whereby the provision of a supporting surface for the subsequent strand is simultaneously maintained during said transportation by the bearing surface (10). To achieve this, a platform (10) that is located in the press outlet (5), that supports the extruded strand and that can be raised and lowered is divided into functional fields (A, B). The rear functional field (B), which adjoins the front functional field (A) closest to the machine, can be temporarily pivoted into an inclined position in relation to the base.
A method of extrusion pressing curved extrusion press profiles, whereby the extrusion press profile is formed in a die of an extrusion press apparatus ahead of a cross beam and then by the effect of external force is curved or bent and in the pressing direction is subdivided into segments, characterized that in the extrusion pressed strand in the press outlet is received by a support surface supporting the strand at its underside and after the separation of a strand segment, the latter is moved out of the press flow by the support surface and transported away and whereby during the transport away the support surface is simultaneously ready to act as the support surface for the subsequent strand.
