  • the side edge 33 of the item 6 can come into contact with the side mark 38, whereby the good 6 is aligned.
  • the movement of the friction rollers 20 is stopped in the lateral direction, so that the good is transported only in the direction of arrow 31 on. This is done until the leading edge 35 of the stock 6 comes into contact with the leading edge stops 40.
  • the front edge of the Guts 6 is exactly aligned and compensated for any skew.
  • FIG. 4 the front edge of the Guts 6 is exactly aligned and compensated for any skew.
  • the front lays 39 are now lowered, for example, so that the good can be transported on.
  • the side edge 33 and then the front edge 35 of the product 6 are aligned.
  • the above-described moving the friction rollers 20 can be continued in the direction of its axis of rotation 21 until an alignment of the leading edge 35 of the Guts 6 has been made to the leading edge bumps 40. In this way Under certain circumstances, the quality of the alignment can be further improved.
