Patent ID: 6915831

Claim:
A cord-wrapping device, comprising: a cradle; a first drum mounted on said cradle for rotation about a first axis relative to said cradle, said drum having an upstream end and a downstream end and defining a steeply inclined inlet surface portion; a first slightly inclined surface portion adjacent said steeply inclined portion; a second surface portion adjacent said first slightly inclined surface portion, wherein said first slightly inclined surface portion has an acute upstream angle relative to said axis of rotation, and said second surface portion has a smaller acute upstream angle of taper relative to said axis of rotation than does said first slightly inclined portion; a first cord mounted on said first drum, said cord having a diameter; and a feed guide fixed relative to said cradle, said feed guide directing said cord onto said steeply inclined portion as the cord wraps onto the drum, wherein the slope of said steeply inclined portion is sufficient that a load sufficient to keep the cord taut as it winds up onto the drum is also sufficient to cause the cord to slide down said steeply inclined portion toward said first slightly tapered portion and to push preceding wraps of said cord along said first slightly tapered portion as the drum rotates.
