A yarn lifting element, which is provided on a positive thread regulating wheel, comprises straight yarn-bearing surfaces whose position cannot be displaced by the yarn, enabling the yarn to slip in relation to the thread feeding wheel when required. The device comprises a plurality of parallel unit cells, each of which is a mixer cell type converter having a differential data switch section connected in series to a differential LO-switch pair. The laminate includes a first constraining layer, a second constraining layer and a viscoelastic damping layer disposed between the first and second constraining layer.
