The invention relates to a machine for the continuous production of bricks, slabs or the like. In the along a support device, a closed pallet line in the direction of a material feed hopper and an IreUwerk / eug mu.els that forms the surface of the Maienai placed on the pallets A jerk device is advanced before em end-Ιο it drive organ with a down below one of ηnni part of the support device formed Amriebsverbindenden Arbeilsirum and a number of SiinmcbSgan pivoted Amriebsele pensions showing each of which is mil one cmc according to indicative investment pool of the range, hm. Miinehmernase and with a lunrungs.e.l provided .st. which *.,!,. nd the movement of the sticking element en.

Be, such machines for creating tiles Slabs, bricks. Blocks made from material such as cement Plastics, bitumen. Asphalt, etc., a material band is laid on the closed pallet string and shaped. that then to the junction of the Pallets being cut up.

The object on which the invention is based exists now, in a machine of the type mentioned at the outset, to train the rearward device in such a way that the closed pallet string with constant Speed moved through the working area of the machine.

This is achieved according to the invention in that the rear-facing contact surfaces for the driver lugs are arranged on the undersides of the pallets and that the guardrail is one of a close the beginning end of the Arbcitstrums in the direction of movement of this strand extending, under a pointed Angle in the direction of the drive track inclined first area and a near the output end of this Trums arranged, relative to the first area at a smaller angle than the angle of inclination of this first region having inclined second region, wherein the first region has a length that is at least is equal to the distance between two successive drive elements.

The claimed nature of the different inclination of the two guardrail areas has the effect of that the first in operation in engagement with the underside of a pallet driving nose on the inclined first area with one of the desired constant feed speed wedge of the strand enlspre-

Each drive element is preferably pretensioned in its pivot axis in the sense of a backward movement of the movement with respect to the endless drive and the guide rail on the abrasion part is designed in such a way that the drivers can be removed from the pallet as a result of their pretensioning jerks and. Further refinements of the invention are contained in claims i and 4.

In the following, the invention is applied to an in the drawing dargeste'lten exemplary embodiment explained. In the drawing, FIG. 1 shows a side view of the entire machine,

The pallets J are the machine by means of a ! iiiderers 25 fed, which is slightly faster than the Reverse device is driven so dall the pallets be placed on the rails 2 of the support device.
