when stored in the shuttle elastically between the brake parts 25 and 21 the t shaped end portion 25 then entering the opening 27 reliably prevents random release of the end of the pick or weft thread 31 from the brake 19 fluff lint and other contaminants cannot be blown by the air jet from the second chamber 12 into the surrounding atmosphere by placing as shown in fig4 an external shield filter 33 this filter is not strictly necessary since the bristles or hairs 17 also retain fluff or lint a suitable filter 33 is for example a gauze fabric or similar air pervious lint filter material it may occur that the weaving loom in which the method and the shuttle construction is to be used is subject to sudden stopping for example upon response of a 34 stop motion 34 device or other safety apparatus it has been found by experience that under such conditions the weft thread is not always properly introduced into the shuttle it may then occur that the weft thead element actually introduced into the shuttle has excess length due to the u shaped formation of the storage chamber for the weft thread possibly occurring excess lengths will not have undesirable consequences since such excess lengths may merely be stored in the second chamber portion 12 and thus will not leave the shuttle and thus be introduced into the shed and form an weaving error or defect placing the bristly region 17 into the second chamber has the advantage that such possible excess lengths of the weft thread will be reliably retained within the shuttle rather than hanging out the hairs or bristles in the.
