Patent number: 5593101Abstract: Spooling apparatus and method utilizing reels having generally radial slots in the end flanges. A filament is guided to a selected reel by a reciprocating traverse sheave. The traverse sheave is moved to one axial end of the full reel to arrange the filament in a winding reference plane adjacent to the inside surface of the flange at that end. A transfer sheave, which moves between the two reels in the winding reference plane engages the advancing filament and deflects it proximate to the empty reel to position a portion of the filament in a direction substantially tangent with the periphery of the empty reel while winding of the filament continues to the other reel. A throw pin momentarily deflects the filament from the winding reference plane to a cutting reference plane on the other side of the flange which places the filament in a position to be snagged by a snagger that rotates with the empty reel and cut on a stationary cutting element in the cutting reference plane.Type: GrantFiled: February 27, 1995Date of Patent: January 14, 1997Assignee: Ceeco Machinery Manufacturing, Ltd.Inventor: Joseph Varga

Patent number: 5487261Abstract: Flat filaments or ribbons are deflected by a system of sheaves to converge the filaments to closing stations proximate to points at which the filaments are tangentially applied to helical surfaces of a central cylindrical core member. Successive sets of filament deflection sheaves stack the filaments into bundles or stacks which can be separated by spacer elements which are applied to a smooth core or the filaments can be inserted into helical grooves or slots in the core. Preferably, adjacent filaments forming each stack are guided to prevent contact or totally eliminate sliding friction until just prior to application in the core. The apparatus and method can be used to produce optical fiber cables, high pressure flexible composite pipes and the like in which the flat ribbons can be wound either within helical grooves formed within the core or about the cylindrical surface of a smooth core.Type: GrantFiled: January 28, 1994Date of Patent: January 30, 1996Assignee: Ceeco Machinery Manufacturing Ltd.Inventor: Andre Varga

Patent number: 5331796Abstract: Fiber optic filaments or ribbons are deflected by a system of sheaves to converge at final filament deflection sheaves which direct the filaments along the longitudinal direction of an assembly table. Successive sets of filament deflection sheaves stack the filaments into bundles which are separated by spacer elements which are likewise guided to the assembly table. Sensors at the final sheaves monitor the tensions in both the filaments and separators and a controller is used to adjust the tensions to compensate for frictional variations upstream of the final sheaves. The table is positioned at an angle to the machine axis so that the stacked filament bundles and separators can be wound about a rotating core by being drawn along the table by the rotating core for staggered and tangential application of the filaments about the core at the downstream end of the table.Type: GrantFiled: September 16, 1992Date of Patent: July 26, 1994Assignee: Ceeco Machinery Manufacturing LimitedInventor: Andre Varga
