When I process certain dark colored fabrics why do I get a loud whistling sound?
It is not always possible to eliminate this high pitched sound. In some cases increasing the temperature of the steam heated cylinder or pre-heating the cloth using the hated can located between the fabric skyer and the rubber belt unit will reduce or eliminate the noise. Increasing rubber belt heated cylinder temperature will also reduce rubber belt useful life.
Some success has been reported in eliminating the noise by hanging a heavy cotton cloth over the emergency cooling water spray pipe and allowing the cloth to just drape onto the top of the steam heated cylinder. Water from the emergency cooling spray is allowed to lightly drip onto the cloth so that very light moisture wicks down the cloth and onto the heated cylinder. This reportedly sometimes solves the problem.
