In one embodiment, the present invention is a method for producing microfibers comprising the steps of: (a) providing a base material; (b) forming the base material in a ring; (c) gripping opposing ends of the ring; (d) flipping one of the opposing ends relative to the other of the opposing ends, forming an upper portion and a lower portion; (e) folding the upper portion onto the lower portion; (f) stretching the folded upper and lower portions; and (g) repeating steps (d)-(f) as desired.

A pipe deployment system that includes a vehicle or trailer. A coil of pipe couples to the vehicle or trailer. A rerounder system is supported by and couples to the vehicle or trailer. The rerounder system changes a cross-sectional shape of the pipe. The rerounder system rotates relative to the vehicle or trailer to facilitate loading of the coil, and un-loading of the product on the coil.

An apparatus for establishing an offset bend in a plastic conduit section having ends and a radius includes a tabletop surface having a front edge, a rear edge, and two side edges; a base surface adjacent the front edge, wherein the base surface is perpendicular to the tabletop surface; an offset block secured on the tabletop surface parallel with and spaced apart from the base surface; a hot box disposed adjacent the tabletop surface and configured to heat plastic conduit; and a water drainage system disposed adjacent the tabletop surface and configured to remove water from the tabletop surface.

A balloon wrapping apparatus for folding a balloon at a distal portion of an elongated shaft includes: a pleating section that forms the balloon with pleats; a folding section that folds the pleats formed in the balloon, along a circumferential direction; and a support base that supports the shaft and can be moved toward and away from the pleating section. The pleating section includes an insertion hole through which the balloon can be inserted, and a back surface hole provided in a back surface on the side opposite to the side on which the insertion hole is provided. The pleating section includes an assisting shaft which can be inserted into the back surface hole from the rear surface side, and an interlock portion interlocking the assisting shaft with the support base. The assisting shaft is formed with a cavity portion.

Provided are a resin filler tube capable of facilitating manufacture and ensuring rigidity in a bent tube portion, and a manufacturing method thereof. A resin filler tube connects an oil filling port and a fuel tank and includes straight tube portions and bent tube portions. The bent tube portions include a bellows-shaped bent inner portion in which hill portions and valley portions are continuous, and a bent outer portion which is formed by a non-bellows-shaped smooth surface. The valley portion of the bent inner portion has a linear outer peripheral surface parallel to a center line of the bent tube portions in a state in which the bent tube portions are in a straight tubular shape, and the linear outer peripheral surface of the valley portions is formed in an entire circumferential range in which the hill portions are formed.

A balloon wrapping apparatus and a balloon wrapping method are disclosed by which a balloon can be wrapped appropriately. The balloon wrapping apparatus for wrapping a balloon of a balloon catheter provided with the balloon at a distal portion of an elongated shaft includes: a pleating section that forms the balloon with wing shapes projecting in radial directions; a folding section that includes a plurality of blades aligned in a circumferential direction, and that folds the wing shapes formed in the balloon along the circumferential direction by moving rotationally the blades; and a rotational support portion that supports a portion of the shaft which portion is on a proximal side of the balloon, and that rotates the shaft in a direction opposite to a rotary movement direction of the blades in a state in which the balloon is positioned in relation to the folding section.

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.

The present invention discloses a system and a method for manufacturing fittings and connections for biaxially-oriented plastic tubes in an integral way from straight preformed tubes, with the possibility of adjusting and distributing the thicknesses as well as adjusting the specific stretching in the different areas of the fittings, allowing them to be reinforced or optimized during the method itself and without causing an increase in the production time or an increase in the raw material used, such that it allows for the manufacture of fittings of different geometric shapes (curves, tapers, couplers, branches, etc.)
