Definitions

• the invention relates to a weaving machine consisting of a reed reversibly adjustable between the shed position and the beat up position and positioned on a stringer of a batten, which is a member of a multimember mechanism.
• the invention further relates to the batten of the weaving machine for positioning the reed and for transmission of a reverse motion of a drive on the reed.
• a reverse motion of a reed is in known weaving machines realized by reversible rotation motion due to positioning of the reed on a swinging batten, which is a member of a multimember mechanism.
• the batten of the weaving machine is composed of a swinging device, on which the reed is positioned, while there is a requirement for a rigid and firm connection of the reed with the batten and sufficient torsional and flexural rigidity of the batten and the reed.
• the batten is composed of a swinging tube pivoted in the frame of the weaving machine and coupled with a driving device, while the batten represents the outer member of the multimember mechanism.
• the increasing efficiency and rotations of weaving machines bring demand on increasing the rigidity of the batten and means the increase of energy and efficiency for its drive.
• the goal of the invention is to increase parameters of the weaving machine and the weaving machine and the batten enabling elimination of relation of the batten inertia moment on swing radius.
• a weaving machine consisting of a reed reversibly adjustable between the shed position and the beat up position, whose principle consists in that a stringer of a batten is a member of a multimember mechanism.
