Abstract Method and device for winding at least one thin elongated fiber optical element onto a rotating drum so as to form a closely wound coil of the fiber optical element in making a fiber optical system from the coil. The fiber optical element is fed to the drum from a direction in retard of the displacement of the point on the drum at which the fiber optical element successively contacts the drum so as to be wound thereon as the drum rotates, thus permitting the fiber optical element windings to be wound on the drum in close contact with each other. An elastic roller is provided in elastically pressing contact with the drum along the entire portion on the drum where the fiber optical element contacts the drum as the same is rotated, thus positively preventing adjacent windings of the fiber optical element to overlap while permitting the adjacent windings on the drum to be kept in close contact with each other.
Method for winding a coil of closely adjacent windings of an elongated element on a rotating drum by supplying the element to the drum from a direction in retard of the points at which the element successively contacts the rotating drum comprising the step of elastically pressing the first and all successive windings of the element onto the drum along substantially the entire length thereof.

Claim 4
Dependent Claim
87 words
Apparatus for winding a coil of closely adjacent windings of an elongated element, which comprises a rotating drum whereon the coil is wound, a guide means for supplying the Elongated element to the drum, the guide means being positioned in retard of the points at which the element successively contacts the rotating drum, and a freely rotatable elastic roller arranged in elastically pressing contact with the drum along substantially the entire length thereof for pressing the first and all successive windings of the element onto the drum.

Apparatus for winding a coil of closely adjacent windings of an elongated element, which comprises a rotating drum whereon the coil is wound, a guide means for supplying the Elongated element to the drum, the guide means being positioned in retard of the points at which the element successively contacts the rotating drum, and a freely rotatable elastic roller arranged in elastically pressing contact with the drum along substantially the entire length thereof for pressing the first and all successive windings of the element onto the drum.
Claim 6
Dependent Claim
63 words
Device according to claim 3, wherein the axis of said elastic roller is slightly inclined with respect to that of said drum so as to give the tendency of positively urging said element which is being contacted with said drum toward the adjacent previously formed winding of said coil by virtue of the rotation of said elastic roller about said inclined axis thereof.
