Abstract
A thread delivery device for a textile machine in which a member associated with a thread delivery arrangement is driven by a driving belt which in turn is driven by a driving wheel whose effective diameter can be varied to vary the speed of the driving belt. The driving belt is engaged with a running surface associated with the driving wheel. The driving belt is provided with holes therein, and the running surface of the driving wheel is formed by a second driving belt with pins on its outer face which engage in the holes of the first-mentioned driving belt to provide a slip-free connection therebetween. The second driving belt is engaged with and extends between the driving wheel and a further guide or idler wheel.
