Leather strap folding machine

[Sonydaze]

I bought my Omac Star 2000 for $200 in good used condition, I think there is some confusion on one costing $8000 from Italy.  I would price them from both Campbell-Randall as well as Simards. Either company should be able to give you info on their capabilities.  If the 220 volt power requirement is a problem, you can get a 110/220 step up step down transformer for $60 - $80 on Ebay.

Instead of glue, try using a suitable width of double sided tape (non-foam).  Much faster, no mess and no fumes.

I tape before running though the folder.. pull the tape backing off just before folding.  Then after folding, I run the strap through a double needle, walking foot sewing machine.  I can probably cut, tape, fold and sew about 100' of strap per hour.

In the past, I have tried several biasing attachments for sewing machines, but could never get one to work well with leather.  Has anyone else had any success with these?

Sonydaze,

The machine was only $200!?   That's a hell of a good deal!   I've sent communications to both companies, so hopefully the pricing isn't too bad.

Is there a specific brand of double sided tape that you use that you would suggest?  I saw that Tandy has 2 types of double sided tape, one that is repositionable, the other listed as an adhesive.

I use some import brand tapes but both Tuck tape and 3M of course are good. Just make sure that it doesn't have a foam centre as it will be too thick. Tandy prices/quality are always suspect.... you don't want a re-positional tape.. lower stick.

I'm curious to see what a new folder costs, please let me know.  Also there is a chance that either company may have a used one.

Perfect, I'll be on the look out for the tape.

As soon as I get info from both companies, I will let you know.  The German company, Sieck, has both a hand cranked and motorized model.   But again, I've been trying to close on a sale since June... http://www.sieck.de/en/machines/belt-manufacturing/

Ok I've got you some pics but I would probably buy a manufactured machine if under $2000 but all the same it would want to be doing a lot of work to warrant that amount. The metal folding, roller and guillotine machine is quite cheap being about $350 au and is likely cheaper over there. The back roller would need to come out and that is easily done. The main trick here is making up the right size folder tool for the job wanted. In the case here a piece of round stock drilled through and funnelled at the front with either a lathe or a reshaped drill bit would work.A cut through at the top and a bit of hacksaw blade ground down soldered in to assist in keeping central and its mostly done. Hope that helps a bit. Regards Brian

Thank youtockyAussie.  I'm definitely leaning towards the Omac machine at this point.  The German machine that I referred to, Sieck, will cost me $900 in guides in addition to the price of the machine.  The Omac can simply be adjusted to get the different folds. 

I have the quote from one Omac dealer and waiting on the other.

I have several OMAC machines and  mostly found them good. A couple of glue machines and a couple of straight line folders although I have made some modifications to make more useful.I would recommend the adjustable guide model I think as even on some leathers as much as .1mm in thickness can make a piece difficult to slide through and just opening or closing a tweak would be a real advantage. If you get one please post some pics off.

Brian,

Which glue machines do you have from them and what type of gluing do they do? What modifications did you make on the machines?  I will definitely share pics once I have one.

In the first pic below ,this glue machine has had a motor and gearbox change. I find it best to use an extraction vent close by to keep fumes down and a small fan to aid in motor cooling. This machine can run up to 3 full days per week. This type can adjust up and down for leather thickness and can have a varying spring pressure. The glue thickness can be varied as well.This type would be good for a light application on your folded strap work.

The second+third pic is a straight edge hand folder which I have modified to foot operation in order to use both hands on the held in piece and enable way faster operation. This machine is good for thick and thin work and putting down high pressure. Mostly good for folded edge wallet type work.

The last pic is a folder that I use when doing hundreds of credit card pocket top folds as it is heated and reactivated the glue which can be applied a day or so before. Also it puts in a crease line at top for better appearance.

Here in these links are some similar machines-https://www.campbell-randall.com/machines/leather-goods-machines/glue-cementing-machines/ict-60-series-solvent-cement-machines/

In case its of interest they have a Camogo CN411 splitter 2nd hand at moment and if you are getting serious about setting up I would take a look at that if you don't have already.

Man I wish they were here in Australia.

I finally decided to get the OMAC Star3000.   I should have purchased it last December as the price had gone up since my initial quote.  I held out a bit because the vendor didn't have it in stock and it would arrive well past the time I needed it to mass produce leather straps for my suspenders. Once I get it going, I'll report back on how it's working out for me.
