The invention relates to a weaving device comprising means for forming a shed of warp yarns, wherein a launching device is disposed on one side of the shed for inserting a carrier which envelopes a weft yarn in the form of a packed clew of yarn, which clew of yarn unwinds from the carrier into an elongated weft yarn upon insertion of the carrier into the shed, and wherein guide means are provided, which guide the carrier during its passage through the shed. Weaving devices of the kind referred to in the introduction are generally known and described in Dutch patent application No. 73/09850, for example. With weaving devices of this type, a weft yarn from a supply bobbin is connected to a projectile, also called shuttle, which projectile is launched by the launching means disposed on either side of the shed, using a medium under pressure, for example compressed air, and carried through the shed via guides disposed in the shed. The object of the invention is to provide a weaving device of the above-described kind, which enables weaving with a carrier which is made of a lightweight material and which has dimensions barely larger than those of the clew of yarn to be inserted into the shed, and which does not have the complex construction of the prior art but which enables higher weaving speeds with fewer weaving flaws. According to the invention, the guide means comprise guide elements which are provided with a recess having an opening larger than the carrier, such that the carrier is movable with respect to the guide during operation in a direction transversely to the insertion direction, and wherein the guide means further comprise blowers, which blowers are at least partially arranged for blowing air jets in the direction of the recess of the guide elements for the purpose of keeping the carrier in the recess during its passage through the shed.
