An Introduction To Twin Loop Wire Binding

Twin Loop wire binding is one of the most popular methods of binding available today. Twin Loop wire binding is also known as double loop wire binding, wire-o binding, double wire binding, or just wire binding and involves taking a preformed C shaped wire binding, placing the spine through the holes on the edge of your document and using a wire closer to close the C shape into a round binding element. Twin Loop wire binding is considered to be one of the most elegant binding styles available on the market and is popular with real estate offices, architects, engineers and marketing departments. However, if you are considering using Twin Loop wire binding in your office there are a few things you might like to know ...

1. Twin loop wire comes in two different pitches (the number of holes per inch). Generally speaking, smaller sized documents use 3:1 pitch (3 holes per inch) and larger sized documents use 2:1 pitch (2 holes per inch). To be more specific, 3:1 pitch wire is available in sizes from 3/16" up to 9/16" and 2:1 pitch wire is available in sizes from 5/8" up to 1-1/4". It is possible to order 2:1 pitch wire in smaller sizes. However, 3:1 pitch wire is not available in sizes larger than 9/16" (the diameter of the wire becomes too thick to fit in the holes).

2. Depending on the size of the documents that you are looking to bind you will need to choose the right wire binding machine. Most wire binding machines either punch the 3:1 or the 2:1 hole pattern. However, the Akiles WireMac Duo Combo binding machine is capable of punching both the 2:1 and the 3:1 patterns. If you are looking for an electric binding machine capable of punching both 2:1 and 3:1 patterns you will need to consider a modular binding punch such as the GBC MP2500ix, or the GBC Magnapunch.

3. Most desktop twin loop wire binding machines include a wire closer that is designed to squeeze the C shaped wires together until they are round. It is important that this wire closer is accurate and closes equally across the entire length of the closer otherwise your documents will not operate correctly. Both Akiles and Renz wire binding machines include high quality wire closers.

4. When binding documents with twin loop wire a good trick to remember is to bind the back cover of the report on the front of your document. After the document is bound you can flip the back cover onto the back of the document and it will hide the place where the twin loop wire meets giving you a more elegant bind.

Twin loop wire is incredibly popular because it allows documents to not only lay flat but to wrap 360 degrees. Twin loop wire is available in a number of colors including: Black, White, Silver, Bronze, Red, Blue, Green, Navy and Gray. This style is ideal for higher end presentations and proposals but should not be mailed without protection for the spine since the metal spines can become deformed.

A rectangular loop of wire that is 10 cm wide and 26 cm long lies in the x—y plane. The loop is in a region where the magnetic field is B = 1.1 T and makes and angle of 50° with the z axis. What is the magnitude of the magnetic flux through the loop?

use the formula :

flux= B*A*COS(Theta)
Area= 0.1m*0.26m= 0.026 m^2
so: flux= 1.1T*0.026m^2*(cos50) = 0.0183 The unit is (Tesla aquar meter)

notice: we used cos Theta becasue it is perpendicular to the plane.
Good luck.
