ABSTRACT:
A guide for prevention of fouling of rope or cable wound on a capstan is a short helical ramp at the driven end of the capstan, which ramp guides the rope onto the cylindrical capstan body. The capstan rotates conventionally; the ramp is fixed concentrically. The ramp winds through an arc which is less than 360.degree.. In another embodiment, an arm connects to the ramp. The ramp with connected arm, is free to rotate near the driven base of the capstan. The rotatable ramp/arm assembly allows the rope to approach the capstan from any radial angle and be properly wound onto the capstan.
