Abstract
A guiding bow (1) for an elongated element (3) in a twisting or winding apparatus. At least part of the length of the guiding bow (1) has a transversal cross-section which is streamlined. The core (5) of the guiding bow may be made of a load carrying material, the sheath (7) of a synthetic material.
Claims1
An apparatus for winding or twisting an elongated element, the apparatus comprising:
- at least one bobbin filled with said elongated element;
- and
- at least one guiding bow which receives said elongated element from said at least one bobbin, said guiding bow guiding said elongated element around said apparatus during winding or twisting;
- wherein said guiding bow includes a core and a sheath completely surrounding the core, said core being made of a load carrying material which resists substantially all forces exerted upon the guiding bow, and said sheath being made of a synthetic material and formed to give said guiding bow a predetermined cross-sectional shape;
- and
- wherein the guiding bow is oriented with respect to a direction of movement of the guiding bow such that during movement of the guiding bow the predetermined cross-sectional shape of the guiding bow ensures that a dimensionless lift coefficient C.sub.L is negative.
