Equipment to help the press in South Side clubs (5,5)

I believe the answer is:

steam irons

I'm a little stuck... Click here to teach me more about this clue!

'equipment to help the press' is the definition.
I can't judge whether this defines the answer.

'south side clubs' is the wordplay.
'south' becomes 's' (abbreviation).
'side' becomes 'team' (a side is a sporting team).
'clubs' becomes 'irons' (iron is a kind of club).
's'+'team'+'irons'='STEAM IRONS'

'in' acts as a link.

Can you help me to learn more?
