The device according to the invention is characterized in that that the housing is divided in cross-section, with the upper part being mounted so that it can be opened or swung up and support rods as well as fadarende guide elements, these are arranged opposite one another both on the upper housing part and on the lower housing part.

The accompanying drawing shows an embodiment of the "object of the invention.

Pig. I a longitudinal section,

Pig. 2 shows a section along II-II of Pig. 1, and

Pig. 3 is another cross section.

The shown guide device for a bar of material on a Swiss type automatic lathe has a tubular housing _t

which is divided in cross section into an upper part 1 and one Lower part 2j the parts 1,2 have from the Pig. 2 and 3 apparent misshapen cross-section.

The LTntorteil 2 is placed on supports 3, whereas the Upper part is attached to swivel arms 4, only one of which is shown, di ^ on axle bolts attached to supports 3 5 are mounted in such a way that the upper part 1 about a geometric axis parallel to the longitudinal direction of the housing can be pivoted or folded up.

In the upper part 1 support pieces 6 are only used and Fastening pieces 7 fastened by means of a screw 8 each, one such screw 8 also for fastening the arms 4 on the upper part of the housing is used. Two support rods 9 extend in the longitudinal direction of the housing through holes in the pieces 6, Resilient material rod guide elements 10 are held with their band parts on the remaining rod sections. These elements, which are expediently made of a glass fiber reinforced polyamide and are injection molded pieces, have one circular arc-shaped central part (Fig. 2).

Similar support rods 9a, support pieces 6a, fastening pieces 7a and resilient "guide elements" 10a are on the lower part of the housing 2 provided, each opposite a corresponding part 6, 7 or 8,
