    • The present invention relates to an apparatus for rolling workpieces, such as sheets or rods, particularly metal foils, comprising: at least one roll stand (1); at least two driven working rolls (2, 3) rotatably embedded in said roll stand (1), co-operating with each other in rolling said workpiece to a required shape and/or size, located orthogonally to a rolling direction (4); at least one of said working rolls (2, 3) is displaceable within said roll stand (1), orthogonally to the direction of rolling (4), and is associated with a pressure unit (13, 14) which is capable to exert rolling pressure (N) to the working roll; at least one of said working rolls (3, 4) is without any back-up rolls, and is embedded in a rotary manner into a bearing bracket (11, 12) located opposite to the rolling area, supporting at least a part of an external surface (9, 10) of said working roll (2, 3) as a trough; means for providing a continuous lubricant film between the external surface (9, 10) of said working rolls (2, 3) and the bearing bracket (11, 12), preferably at least one groove-like fluid chamber (29, 30; 32 to 35) being provided in the part of said bearing bracket (11, 12) embedding said working roll (2, 3); said means is connected to a fluid source; said working roll (2, 3) is connected via said bearing bracket (11, 12) to said pressure unit (13, 14) for transferring rolling pressure; the pressure unit (13, 14) is provided as a means for transferring rolling pressure evenly along the whole length of said bearing bracket (11, 12), preferably as one or more hydraulic power cylinders (H). The main advantage of the invention is that it provides a considerably simpler and more economical solution by eliminating the supporting rolls and by a new embedding system of the working rolls, thus eliminating abrasion and energy loss which are inevitable in the traditional apparatus.

    • In order to produce twisted baking articles comprising at least one outer dough material (58) and at least one inner dough material (56) or dough filling, a nozzle assembly comprises an inner fixed nozzle (4) and an outer nozzle (18) which surrounds the former in a revolving manner. An opening (20) of the outer nozzle (18) is situated in the flow direction behind an opening (16) of the inner nozzle (14) so that the two dough materials flow together at the opening (16) of the inner nozzle (14) and so that, along its path to the opening (20) of the outer nozzle (18), the inner dough material (56) is driven in rotation by the outer dough material (58) and thus compressed.
    • 为了生产包括至少一种外面团材料(58)和至少一种内面团材料(56)或面团填充物的扭曲烘焙制品,喷嘴组件包括内固定喷嘴(4)和外喷嘴(18),其中 以旋转的方式围绕前者。 外喷嘴(18)的开口(20)位于内喷嘴(14)的开口(16)后面的流动方向上,使得两种面团材料在内喷嘴(16)的开口 并且使得内部面团材料(56)沿其到外部喷嘴(18)的开口(20)的路径被外部面团材料(58)驱动旋转并因此被压缩。
