Guillotine Booklet Trimming Help!

Hi all,

so i'm looking for tips.

We have a Xerox Versant with the Square edge trimmer. All great so far, but we're struggling when it comes to then finishing (trimming) the top and bottoms of the booklet. if the cover has full or moderate coverage the booklets become too slippy. When the guillotine clamp comes down it pushes out the stacked booklets and they cant be trimmed, we have to repeat the process several times until we can get lucky and the booklets still flush. This is passable if we're doing tiny print runs, but anything over 100 and it's not doable, plus it's shocking on the alignment like this.

We've tried putting an elastic band around the small stacks we're trimming, with limited success. We've tried guillotining on both sides of the machine, we've tried larger bundles, smaller bundles, nothing seems to be that FIX.

does anyone have any tips on the matter?

Much appreciated.

Not familiar with the equipment. Can you increase the pressure on the clamp to hold the book tighter? Look at the direction of the knife when you cut. Does it move left to right or right to left. If it moves right to left, put the books on the left hand side of the cutter. If you are trimming from 11-1/2" to 11", use the reciprocal dimension, and set the cutter for 1/2". Then you can hold the books in place while you are cutting.

try putting a sheet of uncoated paper between each book.
it might help, then the covers aren't slipping on each other, and might provide just enough "grip".
Otherwise, unfortunately, I think you'll have to trim 1/2 at a time.

If you are trimming the exact same amount off the tops AND the bottoms, you may be able to "counter-stack" the booklets in the cutter (10 where the bound edge is on the right side, 10 where the bound edge is on the left side, etc.). Don't know if this will work. Mostly, our booklets don't have bleeds. When they do, we don't use the inline booklet-maker. We trim the sheets after printing, and then put through an off-line booklet maker/trimmer.

Yeah we've tried that however the margins top and bottom are different, the Versant seems to favour printing low when it comes to booklets, which gives us uneven finishes, but cheers though.

Is the square edge trimmer from Xerox and covered under your service contract? If so I would simply call them up and tell them it is not working properly and let them worry about fixing it.

This may be the same answer Mail Guru gave you . . but the top and bottom trims don't have to be the same . . . counterstack them 10 with the spine on the left and 10 with the spine on the right . . . but keep the orientation the same tops to tops - bottoms to bottoms then you are only trimming the tops or the bottoms at one time . . the little "clips" hold down the back of the stack . . . you attach them to your back clamp so they hold the book still while you clamp it - when you put them on be sure you are compressing the stack similar to the clamps pressure and depending on whether you cut on the left side or see which way you orient the spines against the side of the cutter . ..

We do this all the time, with high quality booklets. We generally do five one direction, and five the other direction to counter the uneveness. You also have to make sure, and hold the books firmly against the back gauge as you bring down the clamp.

makes perfect sense, will give it a shot on the next run, i dont think with the IDEAL 6605 you can change the clamp pressure?


Thanks all
