The single pass filling station comprises a pressure chamber in which the unfilled small pair count unit cables are filled with filling compound and the plurality of unit cables are converged into a single cable as the converged cable enters into a pressure tube where additional filling compound at at least slightly higher pressure is applied thereto. The assembled and filled large cable is then wiped of excess filling compound, wrapped, bound and collected on a take up reel.

Abstract: A wire winding system has a plurality of stations, each with a single take-up turntable driven by a variable speed motor. A mobile transfer cart is moveable to a selected station and is operable to effect transfer of the winding of wire from the full spool on the turntable to a take-up spool on the mobile transfer cart and then after the full spool at the turntable is removed and replaced by an empty spool, the mobile transfer cart will effect transfer of the winding of wire to the empty spool on the turntable. The take-up spool on the mobile transfer cart is constructed and arranged to have its effective outer diameter reduced in order to readily effect removal of the wire wound thereon after the wire is transferred to the empty spool on the turntable.

Abstract: A protective device for use in a continuous casting and rolling process for protecting an eddy current detectoor. A rod arresting means is actuated when a break in the continuous rod or bar is detected. This prevents rod having fins or projections from passing into and damaging an eddy current detector.

Abstract: A wire winding system includes a capstan assembly for drawing wire at a substantially constant speed and a wind-up unit turntable adapted to receive a spool upon which wire is adapted to be wound.
