They put the toothpaste into the tube in one go. There are three injectors which fill the toothpaste tube at the same time......I know this for sure as i have kids and we were watching Come Outside with aunt mable who went to a toothpaste factory to see how it was done.....

You must be talking about some of those toothpastes with stripes, like Aquafresh. The toothpaste is put into the tube while the bottom is still open, it's not going in through the narrow opening at the front of the tube. I'm sure they have a production line where the various colors/types of paste are injected through little tubes at the same time, and after they are all in the wide end of the tube, it's crimped closed. It isn't ever squeezed until you buy it an use it, so the colors aren't mixed together.

Striped toothpaste can be produced by including two different colored toothpastes in an unusual type of packaging. The collapsible tube has two tanks, one filled with each color paste.
Squeezing the tube pushes the two pastes out the opening. The tube nozzle layers the pastes to produce a striped pattern.

The tube is filled with one basic colour, usually white. The other two are dispensed by a special device inside the nozzle.

The paste is extruded like taffy into the large end of the tube then the large end of the tube is heat sealed.

Mechanically injected from the bottom before the tube is sealed.

I think its squeezing the cream out on a cake. Where you have 4 compartments containing different coloured cream, and when you squeeze them out altogether, they do not mix, but appear as seperate colours stuck together,

theres an episode of come outside, its a kids BBC programme, anyway they showed how they pack aqua fresh, they pump it into the tube via 3 separate pumps and that's how it doesn't mix! Do a google on come outside if you want to see if for yourself xxx
