A method of processing profiles in a profile processing assembly, wherein each profile extends along a longitudinal profile axis and has a first end and an opposite second end, the profile processing assembly comprising: - a working machine; and - a profile infeed assembly for transporting the profiles towards the working machine, wherein the profile infeed assembly includes: • an infeed cross transport assembly for feeding the profiles in a cross direction perpendicular to the longitudinal profile axes of the profiles; and • an infeed conveyor assembly for feeding the profiles in a longitudinal direction parallel to the longitudinal profile axes of the profiles, wherein the infeed conveyor assembly comprises an infeed conveyor and a measuring truck, wherein the infeed conveyor comprises a roller conveyor for supporting the profile which has been received from the infeed cross transport assembly, wherein the infeed conveyor has a first end remote from the working machine and a second end adjacent to the working machine, wherein the infeed cross transport assembly is arranged to supply individual profiles to the infeed conveyor assembly and wherein the infeed conveyor assembly is arranged to supply individual profiles to the working machine, wherein the measuring truck engages a profile at the first end of the profile that is facing away from the working machine and is configured to guide the profile along its longitudinal profile axis over the infeed conveyor to the working machine, characterized in that the measuring truck has a number of rest positions along the length of the infeed conveyor; wherein the method comprises: - determining the longitudinal position of the first end of a profile that is facing away from the working machine for each profile that is to be fed to the infeed conveyor assembly by the infeed cross transport assembly; - moving the measuring truck to an optimal rest position of the number of rest positions, which optimal rest position is the rest position between the first end of the infeed conveyor and the first end of the profile and which is the rest position which is closest to the first end of the profile; - transporting the profile from the infeed cross transport assembly to the infeed conveyor assembly; and - engaging the first end of the profile with the measuring truck for transporting the profile along its longitudinal profile axis to the working machine. - a working machine; and - a profile infeed assembly for transporting the profiles towards the working machine, wherein the profile infeed assembly includes: • an infeed cross transport assembly for feeding the profiles in a cross direction perpendicular to the longitudinal profile axes of the profiles; and • an infeed conveyor assembly for feeding the profiles in a longitudinal direction parallel to the longitudinal profile axes of the profiles, wherein the infeed conveyor assembly comprises an infeed conveyor and a measuring truck, wherein the infeed conveyor comprises a roller conveyor for supporting the profile which has been received from the infeed cross transport assembly, wherein the infeed conveyor has a first end remote from the working machine and a second end adjacent to the working machine, wherein the infeed cross transport assembly is arranged to supply individual profiles to the infeed conveyor assembly and wherein the infeed conveyor assembly is arranged to supply individual profiles to the working machine, wherein the measuring truck engages a profile at the first end of the profile that is facing away from the working machine and is configured to guide the profile along its longitudinal profile axis over the infeed conveyor to the working machine, • an infeed cross transport assembly for feeding the profiles in a cross direction perpendicular to the longitudinal profile axes of the profiles;
