Although there are a large number of 4:1 pitch coilbinding machines available on the market there are very few machinescapable of binding documents with 5:1 pitch coil. With this machine,you can choose the pitch of coil that you want to use depending on thesize of your document or the look that you prefer.Bothpunching throats on the 541 Duomac include five disengageable punchingpins. Using these punching pins it is possible to use this machine withall of the most common sizes of paper. Each punch is capable ofhandling documents up to thirteen inches in length. However, thethroats on both punching heads are open so that you can punch longerpaper using a two step process.
On the right hand side of themachine you will notice two small knobs. These knobs are used to adjustthe punching margin on this machine. You can set the machine to punchthe holes closer to the edge of your paper for smaller sized documentsor further away for larger sized documents. Using this feature you canmaximize the strength of your bound documents while ensuring that thepages turn freely on your coils.The DuoMac 541 also includesa high quality pair of spiral coil crimping pliers to help you finishyour documents. These pliers are used to cut and crimp the ends of yourbound document so that the spiral coil does not spin back off the edgeof your book. Weaknesses / Limitations: TheDuoMac 541 is built on the same platform as all of the other machinesin the Akiles Duo Mac line of color steel sheets binding machines. This means that itincludes a wire closer. However, the wire closer is essentially uselesson this machine. Wire is not available in either 4:1 or 5:1 spacing.This simply means that you will need to ignore the closer or use itwith documents that are punched on another machine.Oddlyenough, the DuoMac 541 includes a wire closer that you don’t need andis missing a spiral coil inserter that would be really handy. Akilessuggests that you purchase this machine with a Roll Coil modular coilinserter.
This is an excellent idea. Without a coil inserter you willend up having to spin all of the spines onto the edge of your documentby hand.This machine can bind documents with both 4:1 pitchand 5:1 pitch spiral coil. However, you are still limited to thesupplies that are available for each pitch. Four to one pitch coils areavailable in a huge variety of sizes and colors. However, five to onepitch coils are only available in sizes up to 25mm. Five to one pitchcoils also tend to be slightly more expensive and a little bit harderto find than their four to one pitch counterparts.Althoughthis machine is extremely well built, it is still a manual bindingmachine. Organizations who need to bind large numbers of documents orextremely large documents will most likely find the manual nature ofthis machine is fairly tedious. As a general rule, the DuoMac 541 is agood fit for companies that need to bind up to fifty documents perweek.
