摘要： A razor head, especially a razor blade unit of a wet razor, disposed at the front end of a handle. A single or double razor blade is yieldingly mounted in a plastic housing. To improve the spring or yielding mounting of the single or double razor blades, the latter are secured to a blade member that is displaceably mounted in the plastic housing and can be displaced in a direction toward the rear wall of the plastic housing against a spring force.

摘要： A method and apparatus for continuously feeding rolling stock through a cold pilger rolling mill. A rolling stock--either a continuous or so-called "endless" piece, or a plurality of serially fed, spaced-apart pieces--is initially fed into a roll stand by a feed side drive or transporting arrangement, and thereafter, drawn through the rolling mill by a delivery side drive or transporting arrangement that is located in a rolling direction, i.e. downstream, from the feed side drive arrangement. Once the leading free end of the rolling stock is grasped by the delivery side transporting arrangement, the feed side transporting arrangement ceases to feed the rolling stock through the rolling mill, i.e. forward feeding of the rolling stock is exclusively controlled by the delivery side transporting arrangement. Thus, the critical compressive stresses and/or buckling stresses typically experienced by the rolling stock as a result of pushing the stock through the rolling mill are prevented and the disruptions in the rolling process caused by these stresses are accordingly also prevented. The transporting arrangements are operable independent of each other and at transporting or rolling speeds dependent upon each other.

摘要翻译： 一种用于通过冷轧机轧机连续供给车辆的方法和装置。 一个连续或所谓的“环形”件或多个串联进给的间隔件的轧制坯料首先通过进料侧驱动或输送装置进料到辊架中，然后通过 轧机通过位于沿进给侧驱动装置的轧制方向（即下游）的输送侧驱动或输送装置。 一旦通过输送侧输送装置抓住车辆的前端自由端，则进料侧输送装置停止通过轧机供给车辆，即，机车车辆的前进进给仅由输送侧输送装置控制 。 因此，防止了由于通过轧机推动坯料而导致机车车辆通常经历的临界压应力和/或屈曲应力，并且因此也防止了由这些应力引起的轧制过程中的破坏。 输送装置可彼此独立地操作，并且彼此依赖于输送或滚动速度。

摘要： A device for feeding oblong workpieces, particularly for a cold pilger machine comprises first and second endless conveyors having opposed reaches extending substantially parallel and between which a workpiece is adapted to be fed by engagement with the conveyor. The conveyors are supported in a housing which is rotatably mounted in order to impart a rotation to the workpiece in addition to its transverse feeding movement. The apparatus includes an input or drive shaft connected through a first cam controlled gearing for controlling the rotation of the housing and connected through a second cam controlled gearing for controlling the advancement movement of the conveyors. The second cam controlled gearing includes a belt drive which provides for a variation of operation and a drive through planetary gearing and rotary gear members for effecting the drive of the conveyor elements.

摘要： THE RECOIL DEVICE OF A ROTARY FORGING MILL IS ENABLED TO OBTAIN UNI-DIRECTIONAL ROTATION OF THE HOLLOW, OR WORKPIECE, BETWEEN WORKING STROKES IN SUCH A MANNER THAT THE ANGLE OF ROTATION IS INDEPENDENT OF THE LENGTH OF STROKE OF THE RECOIL PISTON. THERE IS A SHAFT OPERATIVELY CONNECTED TO THE MANDREL HOLDER IN SUCH A WAL THAT ROTATION OF THE SHAFT IS TRANSMITTED TO THE MANDREL HOLDER. THE SHAFT IS ROTATED BY TWO PRESSURE-FLUID OPERATED PISTONS WHICH CAN BE COUPLED IN TURN TO THE SHAFT. THE PISTONS ARE ALSO COUPLED TO EACH OTHER SO THAT AS ONE PISTON MAKES A WORKING STROKE THE OTHER PISTON MAKES A RETURN STROKE.

摘要： Cold pilger rolling mill for cold forming a hollow into a strain hardened tube with a roll stand with rollers mounted pivotably thereon. Efficient milling of long hollows is enabled without reducing the quality of the manufactured tubes. The cold pilger rolling mill has an unwinding device, wherein the unwinding device is arranged and in the feed direction of the hollow is located in front of the front mandrel thrust block such that at the unwinding device a spindle being rotatable around an axis being perpendicular to the feed direction of the hollow with the hollow wound thereon is receivable and in an operation of the cold pilger rolling mill the hollow is unwindable and feedable between the chuck of the front mandrel thrust block and the mandrel bar into the feed clamping sledge and the roll stand.
