and 15 are in contrast produced from soft yieldable or pliant material the jacket surfaces of the drive rollers 14 and 15 assume the respective profiling 2 of the infeed element 1 in the configuration according to fig2 the corresponding contours of the drive roller 14 and the drive roller 15 on the one hand with the infeed element 1 on the other hand do not result in any widening of the infeed element 1 in the engagement region of the drive rollers 14 and 15 the width 19 of the drive rollers 14 and 15 corresponds to the width 18 of the infeed element 1 shown in fig2 is the depth of curvature 33 measured between the associated arrows by which the lowest point of the profiling 2 is spaced away from the lateral edges of the infeed element 1 it is possible for the two drive rollers 14 and 15 respectively of the drive station 13 either to have a drive or to be connected to one another via a gearwheel connection or the like 0043 fig3 shows a deflecting roller 21 about which an infeed element 1 according to the invention is deflected in an open 90 u00b0 deflection 20 the.
