A group of young people, including Watkiss communications director Jo Watkiss's son Ben, are swimming the Thames from Kemble to Twickenham in support of the charity.
The 236km relay is expected to take the team three and a half days to complete and will run non-stop to raise money for the Help the Heroes charity.
Anyone wanting more details on the charity can pick up an information pack from Watkiss's stand (18/ D821) where it is being assembled on a Watkiss document finishing system, which features the company's latest release, a new two-knife trimmer, which can be retrofitted to any existing Watkiss finishing system.
Also launched at the show was the company's near-line 12,000sph PowerSquare sheetfeeder.
The PowerSquare sheetfeeder is on show as part of a finishing system that includes the company's latest book stacker, which was also launched at Ipex.
