the gripping fists 14 if the machine lengths are greater it may then become necessary in order to maintain a secure composite to provide a suitable number of reinforced yarn guides 5 39 in order to thereby increase the number of connecting points the total weight of the yarn guide rod according to the invention is approximately equivalent to the weight of the known tubular yarn guide rod even through the void present in the known construction is filled by the bar body 9 9 39 in the invention the tube wall is reduced to half moreover the carbon fiber reinforced plastic has only approximately one fifth the volume weight as compared with steel with basically the same weight the composite according to the invention also has the same inertia but as compared with the known steel tube it has a markedly improved load bearing capacity in the direction of strain this is because even though the modulus of elasticity of the carbon fiber reinforced plastic is only approximately half as high as that of steel the effective cross sectional area of the composite rod according to the invention is increased quite considerably in proportion to the known steel tube yet this effective cross sectional area is definitive for the possible load bearing capacity of the composite rod concretely this means that in normal operation the additional vibration superimposed on the normal vibration drops to approximately half because of the greater load bearing capacity in the longitudinal direction of the yarn guide rod at the same time the natural frequency of the system increases by a factor of 1 4 and consequently has a markedly greater.
