ABSTRACT:
A jet printer for dye printing a moving web of material by application of a selected plurality of streams of liquid dye. A dye supply tube corresponds to each dye stream and is disposed above a respective dye discharge tube which in turn is disposed above the moving web. A deflecting finger corresponding to each supply tube is pivotably mounted in a housing for selective movement into and out of the path of dye flowing from the supply tube. Each finger is carried by a support block which carries a permanent magnet in the form of a small cylindrical member. An electromagnetic coil in a control circuit is mounted with the core of the coil adjacent a peripheral portion of the magnet. Control circuitry selectively controls the polarity of the coil to attract one end of the magnet toward the coil and the other end repelled therefrom, and when the polarity changes the magnet moves in the opposite direction. Movement of the magnet pivots the respective support block and deflecting finger. When the deflecting finger moves into the path between the supply and discharge tubes the dye is deflected onto an inclined surface and is precluded from contacting the web.
