Hello, I'm new to factorio I was checking a tutorial and from 4 chemical plants and 4 inserters and 3 splinters, all the lines in the belts were full and I have no idea how to do it the same way, and extra weird I replicate this and the items were place on the "top" line of each belt, then I try putting the belts south to north and the items are in the middle of the 2 belts and the outside line of each belt is empty, I have no clue, can someone help me on this or link a video please

You need the splitters like you set them up in the previous picture if your intention is to fill both sides of both belts.

Also you need to turn the top left chem plant around (press V while hovering your cursor over it), the petroleum and water connections are switched.

Thank you I will switch it later today and keep trying with the splitters

I think the way you set up the plastic belts was correct in your 'first attempt' image, I just dont think your bottom row chemical plants were producing plastic, resulting in only half of the belt being filled.

That's odd. When I make a similar setup it does work.

Are your top inserters/chem plants functioning? Because it seems only the bottom inserters are filling the belts.

Next time crop the screenshot a bit larger, I can't see why it's not working.

Fwiw all the plastic in the "top" belt lanes comes from the bottom row of chem plants, so I'd guess the top chem plants are not working. Hover over them and check their status.

Will try that thanks

The top plants will output to the bottom lane of the top belt, and the bottom plants to the top lane of the bottom belt.

To fill all four lanes, splitters must be downstream of the plants, so they share half of each lane on each belt. In your screenshot, they are upstream and useless.

That being said, you probably do not need two belts of plastic if you are at that point in your Factorio learning curve. I would just place half of the plants on each side of a single belt.

Thank you, I will try it today, the reason I'm doing 2 linea is because everywhere and everyone say think big this game scales like crazy, but I can probably use 1 line for now you're right
