"the feeder shutter lever is strikly beloved" I don't understand......

Another this to check is the feeder itself and packaging. The feeders have a little shutter covering the part when the feeder advances. We have noticed a static charge build up in that, or the parts, causing the part to pull out of the pocket when

Good point [engguy], and another thing; if you are using 1.3mm nozzle on a feeder that has a shutter opening of 1.0mm = problem. You could even damage the nozzle. So the main questions remain....

I like to find out more about your feeder manufacturer. Known problems: If the cover tape peel back is located in the pick up window, the tape may lift the component out of the pocket and when the component falls back it could be inverted. The co

Good advises thanks. I'll go thru all nozzles and vacuum check today and tell the programer about PD's and nozzle vs shutter. Should I check at the same time all the vacuum filter ? For the placement test, we use the same feeder at the same position.

I'm not sure it would explain your feed issue, but the main thing that we have found to cause problems is the two nylon gears that pull the tape. The teeth get bent, and they don't mesh together as well, causing the tape to not pull correctly. Or t

Ian was quite right, mentioning the Nitto patent. It is Pat# 4,820,369 from April 1989. The idea is great, but there are quite some hick-ups in practise. P.S. The reasons for the difficulties with the �cover tape curl� are easily explained. Try to

hello, my colleague ProcEng1 is right. The main problems are the gears, which easily are stuck with foil, the shutter, which has to be lubricated and not bend. Air cylinders on the machine have to be changed if you have misfeeds still. They look pret
