Abstract
Method for extending a warp fed to a tufting machine, which includes securing trailing thread ends of the warp to be extended with a holding device, pulling the leading thread ends of a new warp from a thread accumulator, securing the leading thread ends of the new warp with a further holding device, subsequently joining each individual thread of the warp to be extended to a thread of the new warp with a spliced joint, and cutting off and sucking away the two overhanging thread ends of the spliced joint, and an apparatus for carrying out the method.
