摘要： An apparatus and methodology for uniformly applying a compressive force against a filament to pneumatically drive the filament or fiber optic cable against a capstan without any concentrated amount of stress at any point on the filament is effectuated by pneumatically forcing the filament into an equatorial V-groove defined in the capstan. Pneumatic pressure is applied to a predefined segment of the capstan by a pneumatic shoe having an internal shoe pressure chamber. The pressurized gas or air is applied to the segment from the chamber within the shoe into the proximity of the equatorial V-groove on the equator of a disc shaped capstan. The V-groove is vented to atmosphere so that the cable is forced or blown into the V-groove. Side and end clearances between the rotating capstan and the shoe are sized to allow the viscosity of the pressurized gas to operate to retard the escape of the pressurized gas from the predefined segment of the capstan. Annular interleaved baffles may also be provided on the equatorial surface of the capstan and the opposing surface of the shoe to provide additional frictional engagement between the pressurized gas and the elements in the proximity of the predetermined segment of the capstan. Utilizing such an arrangement, approximately 10 kilometers or more of filament can be paid out in approximately 32 seconds or less.
