If a toilet roll is made up of 2 long lines of paper - how do manufacturers get the perfortions on one sheet to line up with the other sheet when the outer length must be longer than the inner?

The layers are together when they are perforated, so the perforations are exactly in line. If they are out of sync. lift the top layer back one turn to correct it. The layers ARE the same length, as it is so thin that the circumference is the same to both layers.

First they put the two long 'pieces of paper' together, then they 'perforate' them both at the same time, and usually also put some 'patterning' onto the toilet paper to help hold those two pieces together. Then it is 'rolled up' ... and because paper is so 'thin' and it's wrapped fairly 'loosely' around the cardboard tube, it 'stays together' better ...

The paper is flat when it goes through the perforating machine and is rolled up later.

They are not different lengths they go under the perforation head together

you can do it by taking the top sheet back over the roll and that will line up.

They are not lineed up they are millimeters apart as the roll goes round
