<p>Weaving technique where weft yarn is inserted into the warp shed without using a shuttle, described as 'insertion by inertia', throws the weft into the shed in the form of a loop ('thrown' pick), and the weft continues to move by kinetic energy, being held by a gripper outside the shed ('held' pick). The weft is inserted in pre-determined lengths from a store, and the collected yarn is held at a point at a length equal to the width of the pick. The weft yarn is then thrown in the form of a loop. The kinetic energy of the 'thrown' pick develops a force which brings the weft yarn to its unwinding point again, and the yarn is displaced once more to provide a reserve length. The weft insertion mechanism reduces wear and tension on the weft yarn, and provides a simpler loop-forming system than known methods.</p> |
