ABSTRACT:
A grooved traverse drum for use in a drum winder incorporates a cylindrical abrasion-resistant piece which is slantwise inserted therein in a shallow yarn guide groove portion. The cylindrical abrasion-resistant piece elongates substantially in the direction in which the shallow yarn guide groove portion extends. Such abrasion-resistant piece has a notch or indentation formed in its one end peripheral surface and is positioned with respect to the shallow groove portion such that the notch takes place substantially the whole of the shallow groove portion at the crossover point such that yarn guided by this shallow groove portion only contacts the notch in the abrasion-resistant piece.
