The present invention relates to a yarn storage device for a yarn processing machine, a method for supplementing a yarn store in said yarn storage device and a yarn processing machine provided with said yarn storage device, wherein the yarn storage device comprises storage units (2, 7) and loading means (3) in order to add yarn in a selected storage unit, wherein at least one storage unit comprises a winding holder (7) that is provided to keep a yarn store in a state wound round a holder body (7c), and wherein preferably yarn is added in windings with a winding diameter (D.sub.1) that is greater than the radial dimensions (D.sub.3) of the holder body (7c).

A method of winding fibre to create a tubular winding by using at least three different motions to create interlocking segments. The interlocking segments may have at least one fibre parameter that is different, such as colour. The tubular winding may be bent into a curved shape so that a portion of each of the segments is visible.

The present invention generally relates to manufacturing of a composite armature, more particularly, to apparatuses for helically winding of a winding roving about a rod when manufacturing a composite armature. There is provided is a helically winding apparatus allowing use of internally unwound roving bobbins instead of sheaves. The helically winding apparatus for a composite armature production line, the apparatus comprising: a disk-shaped creel (1) rotatable about its axis, wherein at least two drums (2) designed to have internally unwound direct roving bobbins mounted therein are mounted on a base of the disk-shaped creel, and each drum is configured to rotate about its axis and to unwind direct roving threads from a bobbin inner side, wherein each drum for placing bobbins of the direct roving is provided with a thread tensioner (3) placed thereon to provide twisting of the direct roving thread relative to its axis when the drum is rotated about its axis to form a twisted roving, wherein the helically winding apparatus further comprises: a cylindrical sleeve (4) positioned in a center of the disk-shaped creel and configured to pass a reinforcement rod through a center of the cylindrical sleeve, wherein the cylindrical sleeve has holes (5) for passing the twisted roving therethrough and helically winding of the twisted roving about the reinforcement rod when the disk-shaped creel is rotated about its axis. A technical effect provided by the claimed invention is an increased produceability of the helically winding apparatus, increased productivity, and a reduced rejection rate.
