A shuttle for a circular loom comprises trunnions supporting and turning together with a winding core of a tape package. One of the trunnions carries a brake disc co-operating with a brake shoe carried by a pivoted lever which is connected to a rocker shaft by a spring. An arm on the shaft is spring-biassed to rest on the tape unwound from the package. If the tape slackens or breaks, the arm and hence the shaft turn to pivot the lever and thereby apply more pressure between the brake shoe and rotating brake disc.
