Abstract: A printing system is disclosed wherein ink is emitted from a nozzle as entrained in a jet of air. The ink is introduced onto an ink wall from an ink passageway and a fluid passageway has an outlet directing air at an angle onto this ink wall to cause ink to flow along the wall and form into ligaments and eventually part from that wall as droplets. The droplets part from the ink wall primarily at a tip wall which diverges out of the air stream. In a preferred embodiment there are two such ink walls and the two flows of ink droplets converge to form a single stream. A printing head contains a plurality such as seven such nozzles in a row and then relative movement of the printing head and the printing surface together with controlled pulses of the emitted ink will cause alphanumeric characters to be imprinted on the printing surface.

Abstract: A machine is disclosed to bag powdery material wherein primary and secondary preconditioning chambers are used, having a volume sufficient to give enough time for the powdery material to become de-aerated. This de-aerated powdery material is then supplied to a bulk filling station and a dribble filling station. Bags spouted at the bulk filling station are filled to about 90 percent of their normal capacity and are then moved laterally to the dribble filling station whereat the bags are rapidly filled to a weight close to the desired exact weight and by automatic speed changing means filled to exact weight at a slower rate. The bags are supported at the top by grippers at both filling stations with the calibrated weight scale being actuated by weight on the grippers at the dribble filling station. An auger at the bulk filling station forces the powdery material down into a generally closed bag to force the bag open by the incoming material to thus keep air out of the bag as much as possible.

Abstract: A sift-proof, leak-proof bag formed from a gusseted, multi-walled tube of paper having stepped plies and bag walls at each end of the tube for attachment to the bag side walls to provide closed bag ends.

Abstract: An engraving blanket which comprises an engraveable layer of live resilient rubber material vulcanized at one face to a face of a base layer of nonhard, nonresilient rubber material. Talcum powder is evenly dispersed between the vulcanized faces of the two layers to control the degree of adhesion between the two. This permits selected portions of the engraveable layer to be cut out and stripped from the base layer to produce a printing design and yet provides sufficient adhesion to keep the layers together during use of the blanket.

Abstract: The openable end of a collapsed bag is aligned in an alignment station on the base of the bag aligner machine. The bag is removed from a bag pickup station by a pick-off arm and moved to a preliminary position. At this point the bag is transferred to a bag holder which moves upwardly relative to the base to move the openable end of the bag into a bag-edge locator. This locator includes first and second alignment members which are interconnected in generally a V configuration and the bag openable edge is moved by a first motor into the open V end between the first and second alignment members to abut the closed V end under the urging of the first motor and additional urging of resilient means. This positively locates the edge of the bag so that it may be subsequently gripped, opened and then filled at a subsequent filling station.
