Abstract: Disclosed is a net knitting method. The knitting method comprises: leading multiple first thread materials (3a) and second thread materials (3b) through first rotating members (13a?, 13b?, 13c?) and second rotating members (13a?, 13b?, 13c?) respectively, and cyclically and repeatedly performing the foregoing process through a step of rotating the first rotating members and the second rotating members simultaneously for an odd number of half circles and a step of staggering a first base (11?) and a second base (11?), so as to form an obliquely knitted net. The knitting method can improve the structural strength of the net.

Abstract: A stranding of long winding material using a substantially cylindrical rotary body. The rotary body includes a first passage for guiding a first winding material through the cylindrical rotary body and a second passage for guiding a second winding material through the cylindrical rotary body. The first passage connects a first offset inlet on a first end side of the rotary body to a first offset outlet on a second end side of the rotary body, which opposes the first end side. The second passage connects a second input, arranged on a surface of the rotary body extending between the two end sides, to a second offset output on the second or first end side of the rotary body.

Abstract: The present invention is a multi-layer guidewire which has a first core metal and a secondary metal formed on the outer periphery of the core. During manufacture the composite structure is twisted providing superior mechanical properties to the finished guidewire.
