Abstract: A projectile or gripper shuttle loom includes a weft-yarn delivery device with an overend-unwinding delivery unit that has a stationary, brakeless drum, a withdrawal eye arranged coaxially downstream of the drum and a yarn brake controlled in accordance with the loom cycle. The thread path is enclosed by at least one hollow body extending from the circumferential face of the drum to the withdrawal eye at least in one axially limited segment. The hollow body has on its inner side coaxial to the drum axis a plurality of ballooning, disturbing and braking elements which protrude inwards without touching the drum while forming projections and deposit surfaces for the weft yarn.
