The present invention relates to a continuous process for producing a profile comprising at least one core made of a polyurethane foam or a mixture comprising a polyurethane foam, at least one jacket made of at least one thermoplastic material, and optionally at least one foil between core and jacket, to a profile produced via said process, to the use of this profile for producing windowframes, doorframes, or in the fitting-out of interiors, or in apparatuses in which, during operation, temperature differences arise between interior space and exterior space, and also to an apparatus for carrying out the process of the invention.

1. A continuous process for producing a profile consisting of: (i) at least one core made of a polyurethane foam or a mixture comprising a polyurethane foam, (ii) at least one jacket made of at least one thermoplastic material, (iii) optionally at least one foil between the at least one core and the
1. A continuous process for producing a profile consisting of: (i) at least one core made of a polyurethane foam or a mixture comprising a polyurethane foam, (ii) at least one jacket made of at least one thermoplastic material, (iii) optionally at least one foil between the at least one core and the at least one jacket, (iv) optionally at least one fillet that has been bonded to the jacket and to which further fillets are optionally bonded, and (iv) at least one reinforcement, the process comprising: (A) optionally introducing the at least one foil into a gripper-belt which has a shape of the profile;(B) introducing at least one liquid, foamable reactive system for making the at least one core comprising at least one polyisocyanate and at least one higher molecular compound with groups reactive towards isocyanate groups, into the gripper-belt in such a way that any foil present at least to some extent encloses the precursor material;(C) shaping the at least one core in the gripper-belt;(D) optionally cooling the shaped at least one core from (C);(E) introducing the at least one core from (C) or (D) into an extruder with an attached extrusion die for producing hollow profiles to sheath the at least one core with the at least one jacket and obtain the profile;(F) optionally cooling the profile from (E);(G) optionally cutting the profile from (E) or (F);(H) optionally bonding the at least one fillet to the at least one jacket and optionally bonding the further fillets thereto; and(I) introducing the at least one reinforcement into at least one of the gripper-belt and the extrusion die of the extruder in at least one of (A) (B), and (E), respectively, so that the at least one reinforcement is present in the profile between the at least one core and the at least one jacket or entirely within the at least one jacket, wherein the at least one reinforcement comprises a strip-shaped reinforcement. 2. The continuous process according to claim 1, wherein the at least one thermoplastic material is selected from the group consisting of a polyolefin, a polycondensate, a polyadduct, a wood-plastic composite, and a mixture thereof. 3. The continuous process according to claim 1, wherein the at least one foil is present between the at least one core and the at least one jacket in the profile. 4. The continuous process according to claim 1, wherein the at least one fillet is bonded to the jacket in the profile. 5. The continuous process according to claim 4, wherein further fillets are bonded to the at least one fillet in the profile. 6. The continuous process according to claim 3, comprising (A) introducing the at least one foil into a gripper-belt which has a shape of the profile. 7. The continuous process according to claim 1, comprising (D) cooling the shaped at least one core from (C). 8. The continuous process according to claim 1, comprising (F) cooling the profile from (E). 9. The continuous process according to claim 8, comprising (G) cutting the profile from (E) or (F). 10. The continuous process according to claim 5, comprising (H) bonding the at least one fillet to the at least one jacket and bonding the further fillets thereto. 11. The continuous process according to claim 1, wherein: the at least one foil is present between the at least one core and the at least one jacket in the profile;the at least one fillet is bonded to the jacket in the profile;further fillets are bonded to the at least one fillet in the profile; andthe process comprises:(A) introducing the at least one foil into a gripper belt which has a shape of the profile;(D) cooling the shaped at least one core from (C);(F) cooling the profile from (E);(G) cutting the profile from (E) or (F); and(H) bonding the at least one fillet to the at least, one jacket and bonding the further fillets thereto. 12. The continuous process according to claim 1, wherein the gripper-belt has a shape of the profile and at least two shaping jaws. 13. The continuous process according to claim 12, wherein the gripper-belt has a shape of the profile and at least three shaping jaws.
