Abstract
The weft-preparation device for superposed shed type weaving machines comprises a weft measuring drums, a weft-severing device with a plurality of shears and a weft insertion device. Each shear comprises a blowing tube which conveys a weft yarn. The insertion or picking device has a guide duct for the weft which is open on one side and which is closable by a closure member. The severing device places before the guide duct entry whichever shear is guiding a weft for severance. The duct is then closed. When a weft has been fully picked in a picking comb, it is severed. The weft then remaining is conveyed by the blowing tube by way of the picking device into the next picking comb which has meanwhile entered. The severing device is then lowered one step at a time and the subsequent wefts are severed and picked.
