Abstract
A device for supplying weft threads in a weaving machine includes a bobbin support over which it is possible to slip a bobbin, a thread guide duct extending axially through the bobbin support and which includes an opening at the top for permitting entry of a yarn end into the thread guide duct, a blower for providing an airstram in the thread guide duct, the airstream flowing towards the top of the bobbin support, a prewinder, and a suction and blower device mounted at an entry of the prewinder. The blower and the suction and blower device are simultaneously switched on to create an airstream between the thread guide duct and the prewinder to carry the yarn end situated in the thread guide duct to the prewinder.
