1. A crimping station comprising a crimping tool designed to crimp a sleeve around a first end portion of a thread and around a second end portion of the thread in order to join and fix together said first and second end portions, wherein said crimping station comprises a sleeve preparation subassembly which has a feed device that supplies a metal strip and conveys said strip as far as a shaping device designed to plastically deform said strip in order to give said strip a concave curved cross section, so as to obtain a preformed strip, and then as far as a cutting device which is designed to sever a portion of length of said preformed strip in order to obtain a sleeve preform that a loading tool places within the crimping tool, such that said crimping tool can press on and close up said sleeve preform, by plastic deformation, to form a sleeve around the first and second thread end portions.
