  • Warper delivery system having constant delivery angle
    Patent number: 5430918
    Abstract: A method and apparatus for delivering a warp sheet onto a beam which includes a pickup beam on which the warp sheet is wound, a delivery device which is spaced apart from the beam for delivering the warp sheet at an angle, a detecting device for detecting any incremental change of angle of the warp sheet as it is delivered onto the beam and a control device which is connected to the detecting device to relatively move the delivery means or the beam in response to any change of angle to maintain a substantially constant angle between the beam and the warp sheet being wound thereon.
