Abstract
An apparatus for stranding optical fiber cores while slackening the same in which optical fiber cores are pushed into core storing spaces which are to be twisted or twisted core storing spaces. A core delivering system has a passage for passing the optical fiber cores therethrough and a gas which flows from the back position of said passage towards the front position thereof functions to send out the optical fiber cores at the inlet side of said core storing spaces. The tensile forces of the optical fiber cores at the inlet sides of the core delivering system are decreased by a winding drum mechanism.
