How is the background cloth of the photography shop fixed on the roller?

Personal experience is that it is best not to connect the new background directly to the axis. But to find an old background first. Same width. The length is about 50 cm. Pick up the old background first. Then pick up a new background. So that even if you put the background at the end, you won't be caught. Otherwise, connect the new background directly to the axis. You will feel that the length is not enough when shooting. Of course, if you buy the background of 1 1 meter, that's another calculation.

If it is fixed. Usually tape will do. If the landlord really wants to do it once and for all. Find some thicker cold-mounted film to fix it. It must be much better than using tape or sol or something.
