The object of the invention is a method for building hoses reinforced with spirally laid fibers, where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibers are unwound from drums (14). The drums (14) are rotated about two axes, the first axis being the principal axis of the drums (A) and the second axis (B) being nearly parallel with the direction in which the fibers are unwound, where the direction of rotation of the drums (14) about the second axis (B) is the same as the direction in which the hose under construction (3) is rotated. The apparatus for carrying out the method comprises a laying head (12) and a drum support platform (15), where the hose under construction (3) undergoes both rotation and advancing motion relative to the laying head (12), and where the reinforcing fibers (10) are unwound from drums (14) through a circular fiber guide (1) The further object of the invention is a method for building hoses reinforced with spirally laid fibers, wherein the reinforcing fibers (10) are laid on the hose surface through a rotating self-adjusting circular fiber guide (2) arranged substantially coaxially with the hose. The invention also relates to an apparatus for carrying out the above method. |

A method of manufacturing a shaft having modified surfaces. The method comprises forming thread grooves on surfaces of a cylindrical-shaped base material for a shaft, continuously winding a length of wire in and along the thread grooves, and compressing a peripheral surface of the base material for the shaft with the length of wire wound and received in the thread grooves, in a direction of diameter reduction to perform plastic deformation of crests of thread ridges between the adjacent thread grooves or the crests and the wire to have the length of wire being fixed to and united with the base material for the shaft. The method improves the hardness of surfaces of a base material for a shaft in a relatively simple manner, and transforms properties of surfaces of the base material for a shaft to make the base material for the shaft applicable to other uses. |

An apparatus and method are provided for forming elongated solid shapes from solid flowable materials such as metal powders, metal shot, fragments or segments of metal in a weldable condition by continuously feeding same to die means which includes two or more power rotated rolls or rollers between which the flowable material is fed and compressed to define its shape. In one form the flowable material or particles may be cold pressured welded into the shape defined by the surfaces of the rolls and their spacing. In another form, heat may be generated within or transferred to the material between the rolls by induction or resistence heating means disposed within or adjacent to the rolls, wherein the heat and the high pressure applied to the material by the rolls serves to fuse or weld the material fed therebetween into a solid porous or non-porous mass as it is fed through the rolls. Heat generated within the compressed material by the compressive force of the rolls thereon may also serve to fuse the material into a solid porous or non-porous mass. |

Apparatus for applying tension to a wire rod while wrapping the rod on a pipe for prestressing the pipe. The tension device includes a frame movable lengthwise of the pipe, the frame having a shaft parallel to the pipe on which is rotatably mounted a bull wheel around which a single turn of the wire rod is wrapped. A hydraulic pump is supported on a torque frame which in turn is rotatably supported on the shaft. The pump is driven in response to rotation of the bull wheel. A load-sensing element is mounted on the frame and engages the torque frame at a radial distance from the axis of the shaft that is substantially equal to the radius of the bull wheel. The hydraulic load on the pump controls the torque load on the bull wheel and hence the tension in the rod as it is withdrawn tangentially from the bull wheel. The reaction torque on the torque frame is measured by the load sensing element, the sensing element thus giving a direct measure of rod tension. |

A machine for winding a body, such as a container, tubular member or the like with a tension cable which is tensioned with an adjustable force, comprises a machine carriage movable at a predetermined speed about the body to be wound. The carriage has a drive shaft, a main drive motor for driving the drive shaft, a clamping wheel mounted for rotation on the carriage for tensioning the cable, and a mechanism for maintaining substantially constant the force in the cable. This mechanism incorporates a brake which is driven by the clamping wheel and is mounted to pivot about a fixed pivot axis upon being so driven, and an auxiliary motor for auxiliary drive of the carriage. The brake transmits energy taken-up during braking to the auxiliary motor. A spring resists pivotal movement of the brake about the pivot axis, so that the brake assumes a pivotal position about the shaft dependent upon the rotational moment transmitted to the brake by the clamping wheel. The energy transmitted by the brake to the auxiliary motor is regulated as a function of the pivotal position of the brake about the pivot axis so as to change the relationship of the speed of the machine carriage to the rotational speed of the clamping wheel in such a manner that the force in the tension cable strives to approach a desired value. |

The horizontal guide is arranged parallel to the mandrel axis. The mechanism for moving the carriage along the horizontal guide includes of an endless flexible linkage whose position is space is set by master guide; the shape of these master guides in the rectangular system of coordinates x, y depends on the relation: ##EQU1## The flexible linkage is connected with the mandrel-rotating mechanism and with the traverse on which the thread guide is mounted. The winding machine also comprises a vertical guide on which a vertical-guide carriage is mounted hingedly jointed to the endless flexible linkage and another horizontal guide on which a carriage is mounted capable of moving along it, the latter carriage being connected rigidly with the vertical guide and linked kinematically with the traverse carriage on which the thread guide is mounted. The vertical-guide carriage is installed on the vertical guide with a provision for moving along it and is intended to transmit motion to the vertical guide from the endless flexible linkage. |

A wire preforming assembly is fixedly mounted on a circular turntable having thereon a plurality of bobbins dispersed in an array to provide a plurality of wires to the assembly equally spaced around its periphery. The assembly and the turntable are coaxially aligned with and relatively rotating about a longitudinally advancing, mandrelled hose. The wires are being directed to the hose by the preforming assembly so that the hose pulls the wires with uniform equal tension and causes them to be simultaneously wrapped thereon in side-by-side parallel helical convolutions. The wire is directed in a helical path around the surface of a preforming tube of the assembly and is bent toward the hose as it is being wound thereon. The bending imparts a characteristic to the wire which causes it to naturally retain the desired helical shape around the hose.

In wrapping wire around a concrete tank to prestress the same, a motor-driven carriage travels around the tank with a sprocket wheel engaging a chain that extends around the tank. Simultaneously, the wire is fed from a supply spool onto a wire gripping drum and is then laid on the outer tank wall with a wire tension established by the difference in peripheral lineal speed between the sprocket wheel (carriage speed) and the gripping drum. This difference in speed stretches, i.e., tensions the wire. Means are provided for sensing the difference in such speeds and to provide for changes in such difference such that the wire may be uniformly stressed when and as it is being laid on the tank.

An apparatus for winding a filament on a straight shank of an intrauterine device includes a rotatably driven chuck to which one end of the IUD is clamped. The straight shank of the IUD is snapped into a notch formed on one end of a bar slidably impaled on a guide spar. The other end of the bar has a threaded semicylindrical groove which engages a rotating threaded rod to cause axial translation of the bar relative to the shank. A slot, communicating with the notch in which the shank is held, is cut into the bar to guide the filament onto the shank in a uniform helix as the chuck and the rod are rotated.
