The invention relates to a method for extruding curved extruded profiles. The extruded profile is formed in a matrix mounted upstream in a counter beam of an extruder system and is subsequently curved or bent due to the effect of external forces and separated, supported and arranged into partial lengths in the extrusion flow by means of a separating robot connected to a higher control mechanism and is discharged to a storage area with the aid of a handling robot. The handling robot is coupled to the separating robot by means of the control mechanism and, like the separating robot, is moved into a starting position in front of the extrusion press.

The invention claimed is: 1. A method of making arcuate profile workpieces, the method comprising the steps of: a) continuously extruding a strand from an output side of a cross beam in a first movement direction; b) bending the strand by applying a force to it transverse to the direction such that the bent strand moves along an arcuate path diverging from the first movement direction; c) simultaneously c1) supporting the bent and moving strand at and to between upstream and downstream ends of the arcuate path with a handling robot moving synchronously with the strand along the arcuate path, and c2) engaging a cutter with the supported, bent, and moving strand and cutting through the strand while synchronously moving the cutter along the arcuate path with the supported, bent, and moving strand from the upstream end of the arcuate path to the downstream end of the arcuate path to cut an arcuate profile piece from the strand; d) after cutting through the strand, returning the cutter to the upstream end of the arcuate path; e) transferring the arcuate profile piece with the handling robot from the arcuate path to a deposition area and then returning the handling robot to the upstream end of the arcuate path; f) while the robot is transferring the piece to the deposition area and returning therefrom to the upstream end, raising a vertically shiftable support up into engagement underneath the strand at the upstream end to support the strand and, on return of the robot to the upstream end, lowering the support down away from the strand; and g) repeating the above steps until the strand is exhausted. 2. The method defined in claim 1 wherein the deposition area is an upstream end of a conveyor, the method further comprising the steps between steps e) and f) of: e1) transporting the arcuate profile piece with the conveyor to a storage area while simultaneously cooling the arcuate profile piece; and e2) taking the arcuate profile piece off the conveyor and stacking the arcuate profile piece in the storage area. 3. The method defined in claim 2 wherein the arcuate profile pieces are transported to the storage area lying on a conveyor in a generally horizontal plane, the method further comprising the step of: e3) tipping the pieces adjacent the storage area into positions lying in generally vertical planes and stacking them in this position. 4. The method defined in claim 1 wherein the strand or the piece thereof is always supported by the robot from below, the cutter attacking the strand from above. 5. A method of operating an extrusion-pressing apparatus for making arcuate profile workpieces, the apparatus having an extrusion press having a cross beam with an output side, a handling robot, a cutter, and a transfer device, the method comprising the steps of continuously extruding a strand from the output side in a first movement direction; bending the strand by applying a force to it transverse to the direction such that the bent strand moves along an arcuate path diverging from the first movement direction, supporting the bent and moving strand with the robot at and between upstream and downstream ends of the arcuate path while moving the robot synchronously with the strand along the arcuate path, and engaging the cutter with the supported, bent, and moving strand and cutting through the strand while synchronously moving the cutter with the robot along the arcuate path with the supported, bent, and moving strand and with the robot from the upstream end of the arcuate path to the downstream end of the arcuate path to cut an arcuate profile piece from the strand, and thereafter supporting the strand at the upstream end by engaging a vertically shiftable support up against the strand; returning the cutter to the upstream end of the arcuate path, releasing the arcuate profile piece from the robot, and transferring the arcuate profile piece with the transfer device from the downstream end of the arcuate path to a deposition area, and returning the robot to the upstream end of the arcuate path to reassume supporting the strand while shifting the support downward out of engagement with the strand. 6. The method defined in claim 5 wherein the transfer device is a fork engageable under the arcuate piece. 7. The method defined in claim 6 wherein the fork has heat-resistant tines. 8. The method defined in claim 5 wherein the deposition area includes a conveyor having a plurality of endless conveyor elements, the method further comprising the step of using the conveyor to move the arcuate profile piece from the deposition area to a storage area. 9. The method defined in claim 8, further comprising the step of cooling the piece while moving it from the deposition area to the storage area. 10. The method defined in claim 9 wherein the conveyor engages the piece from below and has cooling means for projecting a cooling agent on the piece from above. 11. The method defined in claim 9, further comprising the step of: tipping the piece from a position lying in a generally horizontal plane on the conveyor to a position with the piece lying in an upright plane, and stacking the piece upright in the storage area. 12. The method defined in claim 11 wherein the piece is tipped by means including means for optically scanning the pieces. 13. The method defined in claim 5 wherein the cutter and handling robot are suspended from above the arcuate path.
