A process for winding a filament around a winding support. The winding support has a cylindrical shape with dome-shaped longitudinal ends and a roll axis, and is held by a holding device fixed to a base. The process includes the following, occurring in synchronization, feeding a filament, by means of at least one feeding device, towards the winding support, rotating the winding support with respect to the base around a pitch axis of the winding support, rotating unlimitedly the at least one feeding device around a yaw axis of the winding support with respect to the base, and/or rotating unlimitedly the winding support around the yaw axis of the winding support with respect to the base, and rotating unlimitedly the winding support with respect to the base around the roll axis of the winding support.

A sports article comprising an elongate tubular shaft comprised of a fiber-reinforced resin matrix composite material, wherein the elongate tubular shaft has a longitudinal direction and the shaft is multilaminar and includes at least two fibrous layers, each of which is helically wrapped about a wrapping direction extending along the longitudinal direction to form the elongate tubular shaft, wherein each fibrous layer comprises a plurality of oriented structural fibers which are substantially aligned along the longitudinal direction so as to be oriented within +/10 of the longitudinal direction, the oriented structural fibers having a length, along the longitudinal direction, of less than the length of the elongate tubular shaft to form discontinuous structural fibers serially oriented along the elongate tubular shaft. Also disclosed is a method to produce such a multilaminar elongate tubular shaft.

An expiratory limb for a breathing circuit includes an enclosing wall defining a flexible singular expiratory flow passage between an inlet and an outlet and bounding the flexible singular expiratory flow passage and ambient air. The expiratory limb includes one or more regions of the enclosing wall that made from a material that allows passage of water vapor without allowing passage of liquid water, thereby forming a water vapor flow path from the flexible singular expiratory flow passage to the ambient air through the material. The expiratory limb is configured to allow diffusion of water vapor along the flexible singular expiratory flow passage and dry the flow of expiratory gases between the inlet and the outlet.

In a method for manufacturing a spoke unit, the continuous fiber reinforced plastic is led from a middle supporting portion to a first supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the first supporting portion to the middle supporting portion along the back surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the middle supporting portion to a second supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the second supporting portion to the middle supporting portion along the back surface of the mandrel.
