• The Tamerica Tashin TW3100 is a double loop wire binding machine that includes a 3:1 pitch punch, a wire closer and a wire hanger.
• The stylish and compact design offered by the TW-3100 makes it an ideal choice for organizations that have limited space.
• The TW-3100 is designed for binding documents with 3:1 pitch twin loop wire. It is designed for binding documents that are up to 9/16" thick and as long as 14 inches.

Strengths:

• The TW3100 has 40 fully disengageable pins for punching documents that are up to fourteen inches in length. This makes the TW-3100 the least expensive double loop wire binding machine capable of binding legal sized documents.
• The TW3100 has two handles. One is designed to operate the punching mechanism on the machine. Using this handle you can punch up to twenty sheets of paper at a time. The other handle is designed to operate the wire closer. The two handle design of this machine helps to ensure that the wire closer stays accurate over time and reduces stress on the punching mechanism.
• The TW-3100 has fully disengageable dies which means that it can be used to punch any length of document up to fourteen inches long. It also has a four position depth of punch margin control that is used to adjust the distance of the holes from the edge of the paper. This is a useful feature when binding very small books with the TW-3100.
• The TW-3100 is made of metal not of plastic and its metal components are designed to hold up for organizations that need to bind documents every day.
• Like other machines from Tamerica / Tashin the TW-3100 comes with a 2 year warranty. Most other wire binding machines available on the market only come with a one year warranty. The extra year offered by Tamerica shows their confidence in the design of their machine.

Weaknesses / Limitations:

• The concealed wire closer on the front of this machine is durable enough for most moderate volume applications. However, the fact that you have to flip open the compartment to use the wire closer is less than convenient. This design adds an additional step to the binding process.
• The manual nature of this machine makes it ideal for light and moderate volume binding applications. Users who need to bind a lot of books may want to consider a machine with an electric punch.
• The TW-3100 is designed for binding documents with 3:1 pitch twin loop wire. This limits the sizes of documents that can be bound with this machine. Three to one pitch wire binding spines are available in sizes from 3/16" up to 9/16" in diameter. Organizations that need to bind larger sized books will need to consider a machine that punches holes for 2:1 pitch binding or a machine that punches both 2:1 and 3:1 holes.

Recommendation:

• The TW-3100 is an excellent 3:1 pitch wire binding machine that offers legal sized punching and binding.
• However the design of the machine and the fact that it has a manual punch does not lend itself to high volume punching applications.
• Still this machine's metal construction and convenient compact design make it an ideal solution for organizations looking for a reasonably priced feature rich twin loop wire binding solution.
