Abstract
A method of making a spiral wound fuse body comprising a core of insulating material formed by a limp, dead yarn made of twisted together initially sizing-coated strands of fine ceramic filaments having no sizing to leave a conductive residue under fuse blowing conditions is mass produced by spiral winding fuse wire upon a continuous length of the yarn unwinding from a spool upon which the yarn was wound when the sizing was removed. The resulting self-supporting body can be wound into rolls and subsequently unwound so that individual fuse bodies can be severed from the end of the unwinding roll of fuse body-forming material.
