 Re: Embroidering caps
Some caps just don't have the right shape and consequently sew like hell. Only trial and error will reveal what caps run well.
These problems can occur across the same brand of cap too. (ie. some Otto cap models run well on my Tajimas, some just don't work). Although, I have never had an issue running Richardson brand caps. They are a superior cap in every way.
We recently purchased a Tajima "stretch 8" and had the tech in 3 times in 2 weeks. We were breaking a lot of needles on cap jobs. Like 1 or 2 per run.
Turns out the factory set the gap between the needle and the hook too tight. A slight, ie. normal, amount of deflection was breaking the needle on the hook. That gap had to be re-adjusted (should be at least the width of thread). And we had to polish any burrs on the hook.
So check the gap between the needle, at the bottom of the cycle, and the hook. Not the timing but the gap. If it's close then bump the hook assembly back a skosh.
In addition Hirsch reccomends facing the eye of your needles "straight out" as opposed to a few degrees to the right. This is a simple way to increase the gap between needle and hook. |
