An automatic weaving shuttle is provided with a recess for receiving a bobbin having cylindrical bobbin heads. To retain the bobbin head an insert is held in force engagement within said recess, said insert being formed in a substantially U-shaped configuration with two legs conjoined by a cross-piece. Within the legs are formed pairs of sliding guides disposed respectively on each side of the longitudinal central plane of the bobbin. Spring loaded dogs are slidable within said guides and engage the cylindrical surface of the bobbin head. The bobbin is centralized by a spigot engaging within a correspondingly shaped recess in the end of the bobbin head.

Bobbin retainer on a shuttle

A device for monitoring the travel of a yarn, particularly weft yarn in the shuttle of a loom, which device is designed as an assembly or unit comprising a piezoelectric transducer element, a yarn feeler member fixedly bonded with the transducer elements and arranged as a unilaterally clamped flexural vibratory member, and an induction coil operatively connected with the piezoelectric transducer element, and wherein a yarn guide means is provided at or near the free end of the vibratory yarn feeler member such that the yarn when traveling acts upon said feeler member in a restricted area thereof.
