Abstract: A filament winding apparatus that prevents excessive unraveling of a fiber bundle due to variations in the speed at which the fiber bundle is wound includes a hoop winding device having a wrapping table, a bobbin support unit, a braking unit, a slack removal unit, a detector, and a controller. The slack removal unit absorbs slack caused by the difference between winding and unraveling speeds of the fiber bundle. The detector detects whether the amount of slack absorbed is equal to or greater than or is less than, a predetermined amount. When the amount of slack is equal to or greater than the predetermined amount, the controller increases the braking force of the braking unit for braking rotation of a bobbin. When the amount of slack is less than the predetermined amount, the controller reduces the braking force of the braking unit for braking rotation of the bobbin.

Abstract: This invention relates to rolling and in particular to the process of rod coil forming, for instance, of steel and nonferrous metals, and to a set of equipment for its realization. The method of rod coil forming includes continuous rod feeding through a wire-rod guide, forming of waps with a variable diameter by means of speed variation of wire-rod guide rotation and stacking of waps by horizontal layers throughout the height of a coil. The difference of the applied method is in the fact that the rod is fed at a speed of 35-300 m/s. Forming of waps with a variable diameter is realized under the influence of dynamic forces by means of rod declination at the wire-rod guide outlet at an angle of 15-80° with the axis of rotation and its following feeding in a curved concave path with rotation at an angle of 80-90° with the axis of wire-rod guide rotation, in this case speed of wire-rod guide rotation is varied with respect to the following ratio: ? ? ? ? ? 0.

Abstract: There is provided a rotor for a turbo/drag vacuum pump, the rotor comprising an upstream rotor segment of the turbine type made of metal or alloy, and a downstream rotor segment of Holweck type made of composite material. The downstream segment of the rotor has a reinforcing structure made of long fibers that are distributed in a manner that varies as a function of the section under consideration: in the annular connection region connected to the upstream segment of the rotor, the fibers are inclined and/or spaced apart in order to conserve sufficient flexibility for the composite material to enable it to deform so as to track deformation of the metal of the upstream rotor segment while it is in operation; in contrast, the fibers are close together and form turns that touch in the downstream region of the skirt, thereby guaranteeing greater stiffness in order to withstand the mechanical stresses that occur during high-speed rotation of the rotor in operation.

Abstract: A machine for applying one or more protective layers of material onto a tubular member, for example a pipe, in a substantially wrinkle free and continuous manner. The machine includes a brake tension unit for applying a constant tension to the protective material in order to neck down the material as it is applied onto the pipe, and a base unit for supporting and rotating the pipe. The constant brake tension unit preferably includes a conventional disc brake and a mounting arm for holding a core of material in engagement with the brake tension unit. Pressure applied to the rotor slows rotation of the rotor and the attached core which restricts the unwinding of the protective material from the core. Thus, as the material attempts to unwind from the core a preselected force is applied to resist the unwinding. The material is therefore placed under tension and, due to the nature of the protective material, the material elongates and necks down under the applied pressure.
