摘要： The invention relates to a carrier (20) for inserting a weft yarn (22) into the shed of a weaving device by means of insertion means disposed on one side or on both sides of the shed, which carrier (20) at least partially surrounds the weft yarn (22), which weft yarn (22) extends into an elongated weft yarn (22) from an pull-out opening in the carrier upon insertion into the shed, the circumferential surface of said carrier being provided with means that advance the transmission of air by the carrier. The object of the invention to provide a carrier for inserting a weft yarn into the shed of a weaving device, which can be characterized by an improved aerodynamic behavior and consequently a more stable movement through the shed during the 'shot', with a strongly reduced risk of weaving faults. According to the invention, the air transmitting area of the pull-out opening is smaller than or equal to the air transmitting area of the means in the circumferential surface of the carrier that advances the transmission of air.

摘要： The invention relates to a weaving device comprising means for forming a shed (3) of warp yarns (2, 4), with insertion means (30) being disposed on one side or both sides of the shed for inserting a weft yarn (20) formed into a closely packed ball of yarn, which packed ball of yarn unwinds into an elongated weft yarn upon insertion into the shed, said weft yarn having a front yarn end (23) and a rear yarn end (21), seen in the direction of insertion. According to the invention, the weaving device comprises means (10) that orient the rear yarn end (21) substantially in line with one side of the shed. In this way the length of the weft yarns to be inserted can be fully geared to the width of the shed, so that unnecessary yarn waste is prevented.
