Abstract
A frame stave includes a supporting bar designed as hollow body and adjoined by a supporting member for the heddle carrying rod. The supporting bar reaches its bending strength by a massive longitudinal bar of a substantially square cross-section which forms one of the narrow sides. The other narrow side is formed by the leg of an angeled supporting member for the heddle carrying rod. Two extremely thin walled sheet metal members are mounted preferably by a laser welding to the longitudinal bar and the leg and form the two broad sides. A filler body is located in the hollow inner space of the supporting bar which is for instance of a honey-comb like structure in which a plurality of individual hollow spaces or chambers are formed, which are filled by a sound attenuating material which remains elastic. Strips of material which are impregnated by a bonding agent close the filler body off at both sides and are bonded to the sheet metal parts. By this design the extremely thin sheet metal parts cannot buldge and the frame stave achieves a high stability and at the same time an optimal property regarding the sound altenuation due to the filler body with the sound altenuating material contained therein which remains elastic.
