Abstract

In metal print band technology, it is known to use brushes, either fixed or rotating, to remove contaminating material from the print elements and/or the emitter slots of the band. However, even these processes require periodic removal and cleaning of the brushes. This article describes an improvement to these devices that eliminates the need for periodic removal of the band and brushes for cleaning. The figure shows schematically the invention in which a wedge- shaped slotted bracket is mounted beneath the edge of the print band. A special shaped cleaning tool with a U-shaped flexible polymeric handle with elastomeric foam pads of flattened handle ends is then placed over the band with these ends stuck in the wedge-shaped slot. The operator holds the cleaning tool in place and rotates the band by turning the idler rotor.

Emitter Hole Cleaning Tool Without Having to Remove Band

In metal print band technology, it is known to use brushes, either fixed or rotating, to remove contaminating material from the print elements and/or the emitter slots of the band. However, even these processes require periodic removal and cleaning of the brushes. This article describes an improvement to these devices that eliminates the need for periodic removal of the band and brushes for cleaning. The figure shows schematically the invention in which a wedge- shaped slotted bracket is mounted beneath the edge of the print band. A special shaped cleaning tool with a U-shaped flexible polymeric handle with elastomeric foam pads of flattened handle ends is then placed over the band with these ends stuck in the wedge-shaped slot. The operator holds the cleaning tool in place and rotates the band by turning the idler rotor. As the rotor is turned, the cleaning pads are forced tight into the wedge-shaped slot. The emitter holes move between these elastomeric foam pads (which may be soaked with alcohol to enhance cleaning ability). These pads remove dust, dirt, and other debris from the emitter holes. After moving the entire length of band through the foam pads, the cleaning tool is discarded.
