that individual threads 24 do not touch each other in particular the thread guide arrangement 32 may be formed by a eyelet plate 32 with equally spaced eyelets 33 it is advantageous if these eyelets 33 are set around a circle with the eyelet plate 32 shaped in the form of a ring since tangling is then very unlikely even though the emerging threads may leave at time varying angles such an arrangement provides an easy way of preventing mutual interference between the strings 24 the frame 1 comprises a turning axle 34 which by cooperating with guiding wheels 5 through a central trunion nipple or other means may be definitely determined the central axis 34 runs through the guiding arrangement 32 the lapping arrangement 25 is similarly driven from main shaft 9 over a toothed belt 35 in such a manner that the threads 24 move in the direction shown by arrow 36 if lapping arrangement 25 is taken as a frame of reference in fig3 where the lapping arrangement 25 is viewed from below the circulation direction 36 of the lapping arrangement 25 and the turning direction 16 of the frame 1 are similarly indicated in fig2 an intermediate drive 37 for example a stepping drive is provided which is controlled by a program arrangement 13 by the means of which the lapping pattern may be provided with changes in the circulation movement for example stopping higher speed reverse direction may be imposed on lapping arrangement 25 the circulatory movement of the lapping arrangement 25 and the adjustments to the average speed of frame 1 which are controlled by program arrangement 13 are thereby advantageously adjusted to each other there remains the possibility that while the lapping arrangement 25.
