Method for winding a fiber element onto a support. The fiber element having at least two longitudinal portions (Pi) with different characteristics. The method including the steps of supplying the fiber element to the support and associating with each longitudinal portion a respective value of the winding pitch (pi) which is different from the values associated with the portions adjacent thereto. The winding pitch associated with each portion being modulated in accordance with a periodic function.

A package of material for unwinding from a flush end. The package of material includes an elongated winding member to receive a continuous strand of material substantially normal to an axis of the elongated winding member. The continuous strand of material wound about the elongated winding member substantially covers at least one of two ends of the winding member to define a flush end of the package of material. The covered end of the winding member does not protrude beyond the continuous strand of material wound on the winding member. The continuous strand of material is to be unwound over the flush end in a substantially parallel misaligned manner relative to the axis of the elongated winding member. The continuous strand of material being unwound from the elongated winding member is free of obstruction from the covered end of the winding member.

A method for producing a cheese, wherein the cheese rotates around its longitudinal axis and the yarn is subjected to a cross-winding movement while being fed to the cheese and wound thereon, and having a crossing angle, a winding angle and a placement distance associated therewith. The method including the steps of controlling the crossing angle and the winding ratio as a function of the cheese diameter during the winding process while controlling the placement distance so that it increases in conjunction with an increasing cheese diameter thereby preventing deformations and improving the production of cheeses. A cheese produced in accordance with the method of the present invention offers advantages for stacking and during transport.

By using carbon fibers having a fineness of 25,000 deniers or more, the present invention provides a carbon fiber package including a cheese winding package or a coreless package in which an outside diameter of the package, a diameter of a bobbin or an inside diameter of the package, and a winding width are regulated in the specific ranges, a square-end type package in which a yarn width per fineness, wind angles at the start of winding and at the end of winding, and shifting of the yarn are regulated in the specific ranges, and a carbon fiber packed member in which an average bulk density is regulated in a specific range. Those carbon fiber packages and the carbon fiber packed member solve troubles and inconveniences during use, and also packages which have a high winding density and which do not break easily can be obtained.
