Mac 321 is designed to punch two completely different hole patterns.The 3:1 pitch hole pattern has three square holes per inch and can beused for binding documents with 3:1 pitch double loop wire, GBCProclick and 3:1 pitch spiral coil. The 2:1 pitch hole pattern has 2rectangular holes per inch and can be used with 2:1 pitch twin loopwire and with 2.5:1 pitch spiral coil. This means that it is actuallypossible to bind documents with five different styles of binding usingthis one machine.
Both the 2:1 pitch and 3:1 pitch punchingthroats are fourteen inches wide and offer fully disengageable dies.They also have open throats and continuous punching guides. This meansthat it is possible to punch any document that is fourteen inches orless using a one step punching process. Sheets that are longer thanfourteen inches can be punched using a two step process. All you needto do is punch one side of the document using the punch and then flipit over and punch the rest of the holes. The continuous punching guidewill help you line up the holes.
On the right hand side ofthe DuoMac 321 there are two small gray knobs. These knobs are designedto help you adjust the depth of the holes from the edge of your paper.For smaller sized books it is a good idea to set the holes so that theyare close to the edge of the paper. This will help to ensure that yourpages will turn freely. For larger diameter books the holes should befurther from the binding edge in order to provide added strength toyour bound documents.
The DuoMac 321 includes a high qualityheavy duty wire closer on the front of the machine. This wire closer ismade of heavy duty steel components and should have no problemmaintaining its accuracy over time. There is also a wire holder on thefront of the machine that will help you hang your documents on thedouble loop wire in preparation for closing.
Weaknesses / Limitations:
Althoughit is possible to use this machine with 3:1 pitch and 2.5:1 pitchspiral coil, the DuoMac 321 does not include a spiral coil inserter. Itis also important to note that these two pitches of coil can besomewhat difficult to find and are usually produced on demand. If youplan on using this machine with coil it is a good idea to order yoursupplies with lots of time to spare in order to allow for productionlead times.
Each of the different binding styles offered by the DuoMac 321 have their own limitations.
3:1 pitch wire is only available in sizes between 3/16" and 9/16".
Although2:1 wire can be used to bind larger documents up to 1-1/2" in diameter,this machine can only be used with wires up to 1-1/4" in size.
GBCProclick binding spines are only available in three sizes (5/16", 1/2"and 5/8") and in four colors. They are only available in eleven inchlengths.
Three to one spiral coil is available in sizesfrom 6mm up to 50mm. However large diameter coils can be difficultinsert, especially with the smaller square holes that are produced bythis machine.
2.5:1 pitch coil is only designed for bindinglarge diameter books and is available in sizes ranging from 20mm up to56mm. However, this coil will need to be inserted by hand because ofthe slight pitch difference between the holes and the coil.
Withall of the features that this machine has, it can be a little bitintimidating to inexperienced users. There are a lot of handles, knobsand buttons on this machine that can be somewhat confusing if youaren’t sure what you are doing. This machine isn’t really that hard touse. It may just take a little bit of experimenting and reading theusers manual.
