Abstract
A lint barrier for a sewing machine which excludes lint from entering the interior of the sewing machine having a machine housing enclosing the internal workings of the machine. The sewing machine also includes an oil cooler adapted to cool oil circulating through the sewing machine, the cooler including a plenum, a radiator and an air source for moving air through the radiator. A conduit connects the air source to the interior of the sewing machine, whereby air is conducted through the conduit and into the interior of the sewing machine to maintain a positive pressure within the sewing machine interior, thereby preventing the entry of lint into the sewing machine interior.
