One can purchase adapters for that, thus eliminating the need to re-spool.

In a 'previous life' I used to re-spool 620 films onto 120 spools for use in my camera. The 620 film was not as popular as 120 here in the UK, and shops had much short / outdated 620 film to sell off cheap. So, I bought. Doing my own processing, I had plenty of 120 spools in the darkroom.
