Dust Removal for Slitter Section

Published: January 22, 2008

WESTERLY, RI | Maxson Automatic Machinery Co. has developed a vacuum system for its sheeter that removes dust at the slitters for cleaner sheeted stock and minimized dust related defects (hickies) at the press. Suction is applied at the point of slitting removing any debris from the slit edge. The slitter dust removal system is said to be ideal for converting high bulk board substrates or multiple webs of coated papers, eliminating debris buildup caused by the slitting action.

Sheet metal bonnets enclose all but the contact edge of the top slitter blade and bottom slitter ring. Flexible hosing from each slitter is joined to a common manifold that is piped to a blower and duct collection box. Lateral positioning of the slitters and setting the depth penetration of the upper slitters is not impeded. See maxsonautomatic.com.
