Abstract
A cable winding system has a powered spool for receiving the cable in continuous evenly distributed coils. A levelwind mechanism is attached to the spool and guides the cable onto the spool by a pawl traversing a powered diamond screw groove. The levelwind is attached to a load compensated hydraulic system which prevents stresses from being transmitted to the pawl. The levelwind has a sheave to accept cable angularly disposed to the axis of the spool.
Claims2
In a spooling system for evenly distributing continuous coils about a rotating spool having a levelwind mechanism including a diamond screw having an axis of rotation parallel to the axis of rotation of said spool, said diamond screw having a continuous groove formed thereon and a carriage slidably mounted on said diamond screw, said carriage comprising a pawl mounted on said carriage and adapted to follow said groove, a piston rod connected at one end to said carriage and connected at the other end to a hydraulic system, said hydraulic system including a means for detecting the load on said carriage and automatically applying hydraulic pressure through said piston rod to compensate for said load.
