Blanket piling is a major source of waste and lost production for all presses. The build up of lint, paper fibers and coating residue are a direct cause of halftone plugging and “Hickeys”. This piling greatly reduces quality, causes more frequent blanket washes, shortens blanket life and puts additional wear and tear on the press.Mounting the unique TurboCleaner prior to the first print station can alleviate these problems and increase press productivity.

Unlike other “contact brush” cleaners, the TurboCleaner utilizes a proprietary soft cotton buff rotating at over 3400 RPM, similar to a jewelry-polishing wheel. The rotating buffs generate high velocity air currents, which create a low-pressure area at the web surface, producing very high energy levels. This high energy penetrates the boundary layer on the web and lifts all the debris off. These contaminants are lifted off the surface and swept into the vacuum system. An integral “beater” bar is utilized to continuously clean the buffs and prevent recontamination of the web. See the attached sketch.

Micro Web Cleaner

Unlike conventional vacuum or air knife cleaners, the Micro Cleaner’s unique ultrasonic nozzle penetrates the boundary layer formed on a moving web. Small particles are trapped in this boundary layer and remain untouched by conventional web cleaners. The high frequency, high energy air pulses, 100 kHz and higher, generated by this system, break up the boundary layer and expose the trapped particles to the high level vacuum for easy removal.

Conventional systems that are mounted on opposite sides of the web may induce web flutter and damage the substrate. The typical solution is to increase the cleaner to substrate gap, thus compromising cleaning efficiency. Mounting the Micro Cleaner head above a back-up roll maintains a consistent substrate gap. This eliminates the possibility of web flutter and insures repeatable cleaning results.
