1. A device for feeding a first and a second weft thread in a weft direction to a gripper head of a loom, the device comprising:
a coupling unit configured to move back and forth in a warp direction when the device is installed laterally on the loom;
a first and a second feed unit adjacently arranged in the warp direction on the coupling unit, the first and the second feed units configured to feed the first and the second weft threads, respectively, to the gripper head;
a positioning unit configured to move the coupling unit in only a linear axis path in the warp direction in a first position of the coupling unit and in only the linear axis path counter to the warp direction in a second position of the coupling unit; and
wherein the first feed unit feeds the first weft thread to the gripper head when the coupling unit is in the first position and the second feed unit feeds the second weft thread to the gripper head when the coupling unit is in the second position.
