Threading the bobbin on industrial sewing machine

[marilynjenner]

Hi, I have a wimsew industruial sewing machine and am having trouble winding the bobbin. I am threading it correctly but the bobbin just spins around without loading. I have done it in the past but it is now hit or miss. What am i doing wrong.
Thanks

Is this a wind-up?

I don't mean it- I'm just making a post so your thread appears on the Latest Posts list and hopefully you'll get some answers.

I have a 40 year old Singer machine (portable not treadle) and hadn't used it for about 8 years - when I tried threading it the top thread would not take up the thread from the bobbin underneath. We tried everything , in the end I contacted a retired sewing machine repairer who told me exactly what it was. Apparently there is a little rubber belt inside which perishes if not used for some time. It was easily fixed, replaced this belt and gave machine a good overhaul and it works perfectly again - £38, can't be bad for these days! maybe you have a fault similar to this, worth looking in yellow pages. Hope this helps.
