these tension inconsistencies are automatically smoothed out on the aforementioned stretching arrangement for example it may be desirable to hold a constant extension of about 80 between payout rollers 3 and tension rollers 7 8 and 9 afterwards this extension can for example be reduced to a value of about 40 on the warp beam 10 and held at that value the motors 11 and 18 are electric motors and are suitably dc motors it is possible to set the speed of rotation of motor 11 to yield a basic payout speed in operation in a warping arrangement for the warping of elastic threads with predetermined stretching threads 4 are taken from a spool in the creel 1 by a payout roller 3 having a circumferential speed ui and are stretched by a further set of tension rollers 7 8 and 9 having a higher circumferential speed of u2 finally threads 4 are warped onto the warp beam wind 20 of a warp knitting machine s at a circumferential speed of u3 since motor 11 and 18 operate at a constant speed driving rollers 7 8 and 9 and warp beam 20 the relationship between the two sequentially following circumferential speeds u2 and u3 is constant however the relationship between the other two sequential circumferential speeds u1 and u2 is alterable depending upon thread tension the measuring device 6 between the payout roller 3 and the tension rollers 7 8 and 9 determines the tension of all threads 4 the relationship between.
