Abstract
Abstract The flat hollow section member is provided with one or more apertures in at least one of two oppositely disposed walls as well as with an insert of vibration-damping material. The insert is of a thickness to abut each wall and is of greater dimension than the aperture. Also, the insert may be of solid, annular or hollowed shape and may be shouldered to project through the aperture, for example to form a guide surface for the section member. The section member can be used as part of a weaving shaft or as a rod-like or bar-like element in a drive shaft of a weaving machine.
