Disclosed is a method for the production of a tube having, in sections, a non-circular profile by deforming, comprising: a) providing a tube, which has a circular initial profile; b) conveying the tube in a hot, malleable state through a nip, which is formed by squeezing rollers and has a first nip width, which is larger than or equal to an outer dimension of the initial profile; c) adjusting the squeezing rollers for setting a second nip width, which is smaller than the outer dimension of the initial profile, and deforming the initial profile in said hot, malleable state for obtaining said non-circular cross section; and d) adjusting the squeezing rollers for setting a third nip width, which is larger than or equal to the outer dimension of the initial profile, and severing said tube in a region having a circular cross section; so that respective end portions of said tube have a circular cross section According to the invention, the tubes can be connected reliably with connecting-members or other tubes via the end portions having the circular profile using proven tube connection technologies. At the same time there is at least one central section having a non-circular cross section which is of advantage, for example for applications in photobioreactors.

A protective tube attaching method, the protective tube protecting an electric wire of a wire harness, includes inserting the electric wire through a small diameter protective tube and a large diameter protective tube which covers and is shorter than the small diameter protective tube so as to be movable relatively thereto; positioning one end portion of the large diameter protective tube at one reference portion of the wire harness; moving the small diameter protective tube relatively to the large diameter protective tube positioned at the one reference portion, to thereby position the other end portion of the small diameter protective tube at the other reference portion of the wire harness; and fixing the other end portion of the large diameter protective tube in a state that the other end portion of the large diameter protective tube overlaps with an outer circumferential surface of the small diameter protective tube.

A transportable system and method for the in situ eccentric manufacturing of reinforced thermoplastic pipelines in continuous lengths up to 10 miles and from 8 to 60 inches in diameter having a rotating frame assembly with a eccentric spools for application of reinforcing tapes and other components to a polyolefin core pipe, and further having a forming machine for cross sectional shape reduction of the reinforced thermoplastic pipelines to facilitate pulling the reinforced thermoplastic pipelines inside a host pipeline. Also provided are continuous monitoring and marking with application of tape in the hoop stress direction and the axial stress direction as well as saturated tape feeding stations for impregnation of the reinforcing tape for in situ curing.

A balloon wrapping apparatus is disclosed by which a balloon can be accurately positioned and inserted in relation to a pleating section. The balloon wrapping apparatus for wrapping a balloon provided at a distal portion of an elongated shaft includes: a pleating section that forms the balloon with wing shapes; a folding section that folds the wing shapes formed in the balloon along a circumferential direction; a support base that supports a portion other than the distal portion of the shaft, and that makes the distal portion of the shaft insertable into the pleating section and the folding section; and a core metal member to be inserted in the shaft. The core metal member is inserted in the shaft from a distal end position of the balloon to at least the proximal side of a proximal end position of the balloon.

Electrically powered crimp tools are described. Also described are methods of operating the tools and methods of crimping. The tools include a housing, an electric motor, a roller screw assembly, and a jaw assembly. In particular versions of the tools the jaw assembly includes a cam linkage member that is manually displaced by a user to more easily open the jaws after performing a crimp.

A tapered implantable device includes an ePTFE tubular member having a tapered length portion. The tapered length portion provides rapid recovery properties. The tapered length portion can feature a microstructure that includes a multiplicity of bent fibrils.

A method for producing an insulated pipe in corrugated casing (100) comprising the steps of: covering an inner pipe assembly (105) comprising at least one inner pipe (101) with a film (106); dispensing an expandable insulation material (102) in a liquid state between the inner pipe assembly (105) and the film (106) thereby preparing an initial pipe assembly (107) comprising a layer of expanding insulation material (102a) positioned between the film (106) and the inner pipe assembly (105); extruding a layer of outer casing (104) onto the initial pipe assembly (105) before the insulation material has expanded completely, thereby creating a still expanding insulated pipe assembly (118); and leading the still expanding insulated pipe assembly (118) through a corrugator (205) having an inner corrugated surface giving the casing (104) a corrugated shape as the at least one layer of expanding insulation material (118) continues to expand.

A folding method of an inflatable balloon disposed on an outer peripheral surface of an inner tube of a balloon catheter is disclosed. The method includes: disposing the balloon to an inner side of a plurality of first blade portions arranged so as to surround a reference position while maintaining a state where pressure is applied to an inside of the balloon; correcting a bend of the balloon by moving the plurality of first blade portions toward the reference position in the state where the pressure is applied to the inside of the balloon; pleating a plurality of wing portions protruding radially outward on the balloon by further moving the plurality of first blade portions toward the reference position to partially press the balloon while gradually discharging the fluid inside the balloon; and folding the balloon along the inner tube.

Methods and devices of shaping a part during a manufacturing process. The devices include a contouring unit that applies a force to one or more contact points of an index section of the part, and a measuring unit that measures a shape of a virtual index section of the part. The methods include applying a force to the index section of the part and shaping the separate the virtual index section of the part. The shaping can shape the virtual index section to a target shape.
