Abstract
A rod-type three-dimensional weaving method and apparatus sends weft rods from within a rod magazine between groups of warp rods consisting of a large number of warp rods disposed parallel to one another by means of rod pushers substantially continuously by automatically changing a used-up magazine with another one filled with a new set of weft rod groups. To achieve such continuous weaving, a sensor senses a point where one of the rods in the magazine reaches the preset limit for a magazine change, and a control unit acting on the signal from the sensor removes the used-up magazine and brings another magazine filled with a new set of rod groups into the rod filling position. Or the same control unit stops the rod pushers on one side and starts feeding weft rods from the opposite side by employing the magazine and rod pushers on the opposite side of the group of warp rods, with a significant reduction in the weaving time.
