Apparatus to clean ink and coating from contact cleaning rolls

A web cleaning system, comprising:

• a frame to support the system relative to a moving web having a first major surface and a second major surface;
• a first contact cleaner roll turret on said frame;
• and a first roll cleaner on said frame;
• said first contact cleaner roll turret including a plurality of rotatable contact cleaner rolls supported on said first contact cleaner roll turret;
• an active one of said contact cleaner rolls disposed for rolling contact with said first major surface of said web, and an idle one of said contact cleaner rolls disposed out of contact with said first major surface of said web and in operative engagement with drive means to maintain the rotational speed of said idle roll;
• said first contact cleaner roll turret being rotatable to sequentially place said contact cleaner rolls into and out of contact with said first major surface of said web;
• said first roll cleaner mounted adjacent to said idle roll on said first contact cleaner roll turret for movement into and out of engagement therewith and lengthwise therealong;
• said first roll cleaner including an absorbent cleaning material for placement against said idle roll;
• a second contact cleaner roll turret on said frame adjacent to said first contact cleaner roll turret;
• and a second roll cleaner on said frame;
• said second contact cleaner roll turret including a plurality of rotatable contact cleaner rolls supported on said second contact cleaner roll turret;
• an active one of said contact cleaner rolls on said second contact cleaner roll turret disposed for rolling contact with said second major surface of said web, and an idle one of said contact cleaner rolls disposed out of contact with said second major surface of said web and in operative engagement with drive means to maintain the rotational speed of said idle roll;
• said second contact cleaner roll turret being rotatable to sequentially place said contact cleaner rolls into and out of contact with said second major surface of said web;
• and
• said second roll cleaner mounted adjacent to said idle roll on said second contact cleaner roll turret for movement into and out of engagement therewith and lengthwise therealong;
• said second roll cleaner having a porous cleaning material included therewith, said porous cleaning material having a non-alcoholic solvent applied to said cleaning material for placement against said idle roll to remove particles therefrom, wherein said first contact cleaner roll turret and said second contact cleaner roll turret being positioned on said frame to guide said moving web in a substantially "S" shaped path.
