Apparatus for producing a coiled thread package

An apparatus for producing a coiled thread package constructed of a substantially continuous length of thread disposed in substantially annular layers forming a coil, each layer being constructed of a series of loops which progress along the annular layer of the coil, said apparatus comprising:

• a. a receiving plate having a substantially vertical axis;
• b. a frame structure, a thread depositing disc rotatably mounted on said frame structure, said disc being arranged so as to face said receiving plate and having a substantially vertical axis, said axis of said depositing disc being arranged eccentrically with respect to the axis of the receiving plate, said receiving plate and said depositing disc being capable of relative movement toward and away from each other in vertical direction;
• c. means for yieldingly urging the said receiving plate and the said depositing disc into relative movement towards each other;
• d. means for rotating the said depositing disc around its axis;
• e. further means for causing a relative movement between the axis of the depositing disc and the receiving plate;
• f. a through bore on the said depositing disc providing a passage for the thread to be deposited on the receiving plate;
• g. a feeding device for the thread to be deposited on the receiving plate, said feeding device comprising:
• 1. inlet thread guiding means arranged co-axially with respect to the vertical axis of the said depositing disc;
• 2. draw-off thread guiding means integral in rotation with the depositing disc;
• 3. a thread take-up member fixedly secured to the frame structure which supports the depositing disc and arranged on the side of the said depositing disc which is opposite to the side which faces the receiving plate, said take-up member being stationary with respect to the rotational movement of the depositing disc and presenting an annular outer friction surface which is coaxial to the vertical axis of the depositing plate,
• whereby the thread coming from a suitable supply is guided by the said inlet thread guiding means to the said draw-off thread guiding means so as to be laid, on at least an arc of a circumference, onto said annular friction surface in a direction which is contrary to the direction of rotation of the depositing disc, passing from the said friction surface, to the said bore in the depositing disc, so as to be deposited on the said receiving plate upon rotation of the depositing disc, and relative movement between the axis of the depositing disc and the receiving plate.
