A clamping apparatus provides a releasable connection of a harness cord to a lifting heddle of a leno weave apparatus, wherein the releasable connection is configured as a clamping connection. The clamping apparatus has a clamping wedge and a wedge receiver device arranged at the end of the lifting heddle. The wedge receiver device displaceably receives the clamping wedge in the longitudinal direction of the lifting heddle. The harness cord is clampingly grippable between the wedge receiver device and the clamping wedge structure is provided for fixing the clamping wedge in the clamping receiver device.

A pulley for installation in a pulley mechanism of a Jacquard machine has a shaft, a housing having two flank bodies, which are provided to fasten the shaft, so that this shaft extends substantially between the flank bodies, and a pulley wheel, which is provided to be arranged between the two flank bodies so as to be directly rotatable around the shaft. The shaft, prior to assembly of the pulley, is provided with cavities and/or projecting portions for the post-assembly axial securement of the flank bodies in both axial directions.
