Abstract

A device for measuring a weft, particularly a drum type weft length measuring device for shuttleless looms is disclosed. The device is provided with a length measuring drum for coilingly winding a weft supplied from a weft supply bobbin and a pair of weft engaging pins for controlling a winding amount of the weft on the drum and a shift of the wound weft towards the weft drawing-out direction. The weft engaging pins are linearly movable in their own axial directions for protruding from and retracting into the drum, alternately. These protruding and retracting positions are shiftable in the axial direction of the drum.
