Abstract
The invention relates to a shuttle for a weaving machine, of which the shuttle is designed to be alternately transferred from one side of a weave to the other while machine-side guiding elements are constantly intervening, with a left-hand connecting element and a right-hand connecting element for connecting the shuttle to the corresponding transfer element and to a filling (weft) bobbin. The filling bobbin is embodied to be rotationally positively drivable, with a drive that is designed for at least two impingements upon the filling bobbin, namely for either accelerating or for decelerating the dispensing of filling (weft) thread. The invention further relates to a weaving process in which such a shuttle is used.
Claims21
A shuttle weaving machine, comprising:
- a shuttle;
- a shuttle drive configured to alternately transfer the shuttle from one side of a weave to another side of the weave and from a first transfer element on a first machine side to a second transfer element on a second machine side of the shuttle weaving machine, wherein both of the first and second transfer elements are connected to the shuttle during a transfer period;
- a left-hand connecting element for connecting the shuttle to the first transfer element and a right-hand connecting element for connecting the shuttle to the second transfer element;
- at least one bobbin drive mounted to at least one of, the shuttle, the first transfer element, and the second transfer element;
- and
- a filling bobbin supplying a filling thread, wherein the at least one bobbin drive is configured to exert torque on the filling bobbin independent of the shuttle drive such that the bobbin drive causes acceleration of a dispensing of the filling thread from the filling bobbin in anticipation of acceleration of the shuttle.
A weaving machine comprising:
- a shuttle;
- a shuttle drive configured to move the shuttle from one side of a weave to another side of a weave;
- a filling thread bobbin mounted to the shuttle and configured to supply a filling thread, wherein the filling bobbin is arranged one of in alignment with the warp thread direction and perpendicular to the warp thread direction;
- and
- a bobbin drive configured to move translationally with the shuttle and selectively accelerate and decelerate rotation of the filling thread bobbin independent of acceleration of the shuttle.
A weaving process using a shuttle weaving machine to achieve a weave consisting of warp threads and filling threads, comprising:
- moving, by shuttle drive, a shuttle having a filling thread bobbin mounted thereto from one side of the weave to another side of the weave;
- controlling, by a bobbin drive engaging the filling bobbin, a filling thread tension independent of acceleration of the shuttle, the filling thread tension measured through the filling thread bobbin, the shuttle being controlled according to at least one of process data or fabric characteristics.
