A creel threader for use with a creel system that holds a plurality of spools where each spool carries a filamentary material includes a guide supported by the creel, an endless loop carried by the guide, a drive assembly coupled to the endless loop and at least one gripper carried by the endless loop. The gripper receives the filamentary material from at least one of the spools, and the drive assembly moves the gripper and the received filamentary material from the spool to an output end of the creel system for further processing. Related methods of operation are also disclosed.
A self-compensating tension control device for regulating the withdrawal of filamentary material from a spool includes a fixed support that maintains an inverted cam surface and a spindle assembly rotatably carrying the spool. A tension force applied to the filamentary material, in opposition to a biasing force, moves the spindle assembly linearly in relation to the fixed support. A braking mechanism includes a brake drum rotatable with the spindle assembly, a friction band adapted to engage the brake drum and a rocker arm that engages the cam surface. When the tension force applied to the filamentary material is reduced and unable to overcome the biasing force, the cam roller engages the cam surface and causes the friction band to generate a braking force on the brake drum. Withdrawal of the filamentary material at a regular rate occurs when the biasing force is balanced with the tension force.

Linear movement of the spindle assembly and the associated conductive member can be obtained by either a straight line mechanism or a linear ball bushing mechanism. A supplemental brake may also be used.
