Need help trouble shooting and identifying my roller furler

[SV My Luv Too]

Does any one know what style of brand roller furler this is ? I have looked all around it and it has not name or numbers to help me identify it. Also it does not seem to function properly, the top piece will not travel up the tracks, it gets stuck and the tracks have gaps in between them, when I lift the roller furler the gaps go away but as soon as I let go the gaps opens up again.

Any help would appreciated

I don't know the brand but there should be an adjustment, under the drum perhaps? It will allow you to adjust out the slack you are describing and once it is snugged up, the shuttle should go all the way up.
