The invention relates to a device for loops of pretzels, in which case the ends of a U-ft. crazy strand of dough by moving one up and one down to get a common one. * ne, axis arranged perpendicular to the plane of the dough strand around A at least 180 ° swiveling gripper grasped, before the simultaneous swiveling of the grippers is looped into a knot and placed on the middle piece of the dough strand at the end of the swiveling weave. Vorrichtunnen of this type are advantageous over other known Brezolschlzugvorrichtungen because the looping of the knot as well as. Deposition of the knot loops on the middle piece of the dough strand in one operation and thus high production rates can be achieved.

In a known device of the type mentioned at the beginning, the grippers are attached to the ends of a straight double lever movable about the pivot axis. According to diener / nordnuna, the grippers swing during the rchlinnvorganai; in the same direction of rotation around their axis. At the same time the pivot axis must relative to the U-shaped Teinstrnnn supporting sub-layer to perform a movement on the central piece of the Teiastranaes (German Patent 576 78R).

In the case of machine production soq. "Swabian pretzels" need the er-i sections of the te iq st rank for the purpose of Reduction of its cross-section stretched during chlinqing v / eil those desired for this special qeback thin strands close to the one preceding the loop Do not allow the pretzel strand to be formed to the required extent by long rolling. With the well-known one described above Device, in particular, pretzels of the type mentioned above cannot be made sufficiently uniform

™ Generate shape, because the swivel movement of the Grab the end sections of the dough strand during slicing stretched unevenly. Another disadvantage of the known The device is located in the fact that the when looping and translating on the middle piece t'os Ttiiqstranges twisted into ground. This twisting, which in each end section of the Teiπstrannes in the same Prehsinn, but takes place to different degrees, causes the finished knot to straighten up on one side.

k seeks, whereby also the uniformity of the Erc-zelforr is affected. In addition, the known device requires a considerable construction effort, which is mainly due to the additional to the pivoting mobility the gripper provided reciprocating motion of the gripper pivot axis is conditional.

The invention is based on the object of providing a device

Gams-mentioned type so that, while maintaining the advantage of high production output, pretzels, preferably of the so-called "Swabian pretzels" type, can be produced in a sufficiently uniform torrn.

According to the invention the object is achieved in that the f.he are independent of each other on the common axis up and down and in · entoeqen "o set directions are arranged pivotably on different levels.

Due to the correct arrangement and severity of the gripper an even tension or stretching of the end - .S elinitte the strand of dough during the process of forming the knot and thus an evenly thin pulling out of the rope ends achieved.

In a further embodiment of the invention is the fchwenkachse the grapple with reference to the finished Brczelforir. Located on the outer edge of the knot, which allows it to move back and forth the gripper swivel axis is unnecessary. Together not panning in opposite directions'

The gripper has the effect of ensuring that the end sections of the partial strand do not become twisted while the knot is being tied, but rather are only bent in the shape of a honeycomb in the plane of the pretzel shape.

A simple structural design with the possibility of Using conventional drive and control means is inventive
