Abstract
An apparatus for assembling an optical cable comprises a spacer paying-out portion , a stationary ribbon supply unit , a gathering portion and a taking-up portion . The spacer paying-out portion supplies a spacer having a spiral groove in the surface of a long spacer body from a supply reel while revolving around a line axis X-X. The stationary ribbon supply unit supplies a plurality of optical fiber ribbons . The gathering portion forms the optical fiber ribbons sent out of the stationary ribbon supply unit into a cable core by holding the optical fiber ribbons within the spiral groove of the spacer sent out of the spacer paying-out portion and running forward while rotating on its center axis. The taking-up portion winds the cable core on a taking-up reel while revolving around the line axis. A winding roller ( ) having an rotational direction identical to an rotational direction of the supply reel of the spacer and used for winding the spacer or the cable core is installed adjacently before and after the gathering portion whereby to revolve the winding roller around the line axis in synchronization with the revolution of the spacer paying-out portion . Accordingly, it is possible to prevent a twisting of the spacer in the gathering portion resulting from a winding habit of the spacer during a step of assembling cables.
