Abstract: The invention relates to a method for manufacturing tubes and profiles with variable wall thickness over the length. The method comprises the steps of flexible rolling of continuous material strip with variable thickness in the longitudinal direction of the strip material to a final wall thickness which is continuously reduced with respect to the original wall thickness, reshaping the material strip to form a continuous tube or profile and cutting to length individual tube or profile pieces from the continuous tube or profile.

Abstract: A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.

The belt tensioning device, in normal operation, on the slack side between a generator and a main pulley can also be used when the slack side becomes the load side by a blocking mechanism which enables swinging motion of the pulley carrier relative to the receiving and mounting housing in a first direction, and limits or prevents such motion in a second, opposite direction.

Abstract: A belt tensioning device for a continuous belt drive. The device includes a torsion spring assembly (20) with a longitudinal axis (A2) and with at least one torsion bar or torsion tube (32). The torsion spring assembly (20) can be clamped axially and in a rotationally fast way into a rack. A tensioning arm (19), at one end, is arranged at the torsion spring assembly (20) so as to be aligned approximately radially relative to the longitudinal axis (A2). A tensioning roller (15) is rotatably fixed at the other end of the tensioning arm (19). The axis of rotation (A1) of the tensioning roller (15) extends substantially parallel relative to the longitudinal axis (A2) of the torsion spring assembly (20), and the tensioning arm (19) can be resiliently supported relative to the rack so as to oscillate around the longitudinal axis (A2).

Abstract: A method and a device for flexibly rolling a metal band by guiding the metal band through a roll gap formed between a first working roll and a second working roll, and by varying the size of the roll gap in such a way that band sections with a greater band thickness and band sections with a lesser band thickness are obtained over the length of the metal band. In the device and method, the time of contact between each point on the circumference of the first working roll and the metal band is shorter in duration than the time of contact between each point on the circumference of the second working roll and the metal band such that an asymmetric band thickness profile is obtained in a region of the band sections with a lesser band thickness.

Abstract: A device for forming components from billets having a thickness profile which is essentially symmetric to the central plane of the billet, i.e., the billet contains a thickness transition on both sides, and wherein the thickness transitions on both sided of the billet are transferred to one side of the formed such that the side of the formed component is planar. The forming surface of the forming device which faces the side of the billet that has a thickness transition in the formed state of the billet has a shape is adapted to the thickness transition to be realized, and the forming surface of the forming device which faces the side of the billet that becomes planar in the formed state is planar. Due to these measures, it is possible to transfer the thickness transition that originally existed on both sides of the billet to one side of the billet in only one step.

Abstract: A spring band clamp block formed of a plurality of spring band clamps (1), each of which has a spring band (2) and two projecting tensioning ends (3, 4), and which are detachably joined to one another by means of a fastener. The spring band clamp block can be built especially easily for all types of spring band clamps (1) by the spring band clamps (1) being joined to one another, preferably, by means of at least two adhesive strips (5, 6). The adhesive strips (5, 6) are arranged on the spring bands (2), parallel to the lengthwise axis (7) of the spring band clamps (1), and preferably in the vicinity of the projecting tensioning ends (3, 4).

Abstract: A wheel suspension with a wheel-guiding strut in provided which includes a helical compression spring, a shock absorber, and a suspension arm, and which is connected to a body and to a wheel. The helical compression spring is preferably made such that it at least partially compensates for transverse forces on the shock absorber or on the piston rod of the shock absorber. Provisions are made for reducing or minimizing or eliminating the force which is delivered to the steering mechanism and which results from the difference between the components of the helical compression spring forces FF acting in the direction of travel, and thus the reaction forces RF, on the left and right sides of the vehicle.

Abstract: A raised spring band ring which includes a spring band which annularly surrounds one end of a hose, and two clamp ends which overlap one another and which run essentially in the peripheral direction of the spring band ring. The spring band ring when, in the clamping state, has a certain first diameter, and can be spread against its own spring force using a clamping tool to a second larger diameter. Additionally, the spring band ring has a smaller demand for installation space because the clamp ends, when in the clamped state, do not project radially outward from the round spring band.

Abstract: A method for the flexible rolling of a metallic strip in which, during the rolling procedure, the metallic strip is lead through a roll gap which is formed between two working rolls, and during the rolling operation, the roll gap is deliberately changed in order to obtain different strip thicknesses over the length of the metallic strip. A good planeness of the metallic strip can be obtained, and particularly, also for relatively wide strips, in that, during each setting of the roll gap or directly afterward, the deflection curve bending line of the working roll is controlled depending on the setting of the roll gap for the achievement of planeness of the metallic strip.

Abstract: A method for the flexible rolling of a metallic band wherein, during the rolling procedure, the metallic strip is lead through a roll gap which is formed between two working rolls and which is set so that, over the length of the metallic strip, strip sections are obtained with different strip thickness. In order to prevent temperature-related deviations in the thickness and length profiles of the metallic strip, a compensation of the temperature influence effecting the metallic strip is carried out during rolling in order to prevent deviations from the theoretical thickness and/or the theoretical length of the individual strip sections at a default temperature of the metallic strip.
