Abstract: A compensating thread brake useful, in particular, with warping creels. The thread brake has a rotatable roller whose circumference is at least partially surrounded by and drivable by thread. The roller is connected to the rotor of a turbine. A mechanical thread tension comparator by way of its setting member, influences a throttle in the path of the turbine inlet or outlet stream. The setting member may, preferably, be a throttle plate which regulates the inlet or outlet ports of turbine T. In this manner, the thread tension may be controlled without frictional load on the threads or the need to provide seals against oil or the like. Additionally, an eddy current brake can be provided for the nominal setting of the basic thread tension.

Abstract: An arrangement for the stretching and warping of synthetic warp threads under the influence of heat. The arrangement has feed rollers for driving warp threads, take off rollers for driving warp threads received from the feed rollers, with the take off rollers having a higher circumferential speed than the feed rollers. Additionally there are at least two rotatable deflection rollers, of which at least one roller is heatable with the rollers being rotatable in directions opposite to each other, and at least two auxiliary rollers which are rotatable in directions opposite to each other. A feed segment of the thread extends from the feed roller arrangement to the deflection roller proximate thereto and a take off segment of the threads extends from the deflection roller proximate thereto, to the take off roller arrangement.
