d) exact height adjustment of the rulers corresponding reinforcement bar 6 and are from below accordingly the workpiece thickness; secured by further nuts 8

e) Possibility of quick lifting of the ruler. The parallelism of the guide rod 9 to the flank of the workpiece when the height of the marking table plate 1 is present is due to the design derigen. guaranteed by the equidistant attachment of the angle profile 2 to the table top 1

This object is achieved according to the invention by the parallelism of the guide 9 to the stop side solved that the Fühnmgsstange for the ruler support table edge is by the same height setting head by bolts firmly connected to it in a 15 of the distance between the upper flange of the guide parallel to the scribing table plate arranged Tragpro- profits 3 and the guide 9 by corresponding fil for the purpose of presetting the working area height adjustment of the stud bolts 4 causes is adjustable and that the Lmealträ ^ er head on. With the help of the bolts 4, the middle working of the guide rod is displaceable and rotatable. H. the measure of the height between guide 9 has gertes lower part, which is preset in a corresponding 20 and the support of the main ruler 29 Generating recess a perpendicular to the guide so that positive or negative deviations only in rod-displaceable guide piece accommodates, which are to be corrected in a relatively narrow area, The actual carrier head lO / lS / 16 consists of Leg with a lower part 10, which is designed as an angle piece and which is on the guide rod 9 The upper part of the ruler support head is firmly connected so that it can be moved and rotated in such a way that the distance between the upper part and the armed bore hole is stored with the sliding bearing 12, the lower-lower part being precisely adjustable and fixable. part 10 and the plain bearing 12 has a slot-shaped design

Due to the design according to the invention, the thickness of the workpiece can be made accordingly, It is enough that after the selection of the area a quick By the T-screw 22 the carrier and exact height adjustment of the ruler carrier head, head 10/15/16 both against a longitudinal displacement according to the material thickness of the 50 to be marked as well as against a lifting of the main ruler Workpiece, is possible The need to be secured by turning the head, The machined stop side is omitted because the ruler Dem is angled by 90 ° from the guide 9 The main ruler 29 in the carrier head along an ideal guide edge is the leg of the upper part 16 leads is. This type of guidance also allows the zero point 23, which is the pivot point of the ruler, and tear longer workpieces that are over the length of the 55 its position once exactly through the reference edge of the Reach out the marking table, without further ado, because the workpiece and, on the other hand, by the position of the this is rotated and determined according to the already marked reference carrier head on the guide 9, can be realigned vertically.
