FRANKFURT, Nov 26 (Reuters) - The supervisory board of struggling printing press maker Heidelberg (HDDG.DE) reshuffled management and approved a reorganisation to lower its dependence on new sales of machines amid a structural crisis in the market.

Heidelberg's head of sales, Juergen Rautert, will leave the management board in January after a five-year tenure and will relinquish his responsibilities to Chief Executive Bernhard Schreier.

In the process, the company will be split into three divisions, with Press and Postpress being merged into "Heidelberg Equipment" as of the start of its next fiscal year in April.
