Patent ID: 7533843

Claim:
A reel assembly, comprising: a rotatable element configured to rotate about a spooling axis and to receive a linear material being wrapped around a spool surface of the rotatable element as the rotatable element rotates about the spooling axis; a housing substantially enclosing the rotatable element, a portion of the housing defining an aperture configured to receive the linear material therethrough; and a reciprocating mechanism provided with a slot member having an elongated slot, a guide member having an encircling slot, and an elongate member pivotally connected to said housing and interacting with said elongated slot and said encircling slot to produce relative reciprocating rotation between the rotatable element and the housing about an axis generally orthogonal to the spooling axis and at a generally constant angular velocity between endpoints of the reciprocation for a given rotatable element rotating speed about the spooling axis.
