The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

A method and machine for the surface decoration of a basic article comprising ceramic material and having a surface and a printing assembly applies an adhesive material digitally and selectively onto a defined area of the surface. A treatment assembly deposits a powder material digitally and selectively in the defined area, and the powder material in excess arranged on the basic article is removed.

A method and apparatus for applying or dropping granules onto the asphalt coated surface of a moving sheet in shingle manufacturing is disclosed. The method includes sharing each drop between two or more blend rolls with a subsequent blend roll or rolls applying a partial drop directly on top of partial drops already applied by a first blend roll or rolls. High production speeds can be accommodated since each roll can be operated at slower rotation rates and with slower acceleration and deceleration requirements than would be required if the full granule drop were applied during the same time interval with a single blend roll.

Provided is a powder coating device. The powder coating device performs powder coating by inserting peeled parts at a lower end of a stator into a powder flow tank filled with a powder resin and includes: a surface height measurement part measuring a surface height of the powder resin; a peel height measurement part measuring a height of upper ends of the peeled parts; a swing part swinging the powder resin; an air supply part supplying air toward the powder flow tank via a porous body provided below an open bottom surface of the powder flow tank, and flowing the powder resin; and an adjustment part adjusting at least one of an air flow rate, a swing amount of the powder flow tank, an entry posture and an entry amount of the stator according to measurement results of the surface height measurement part and the peel height measurement part.

Coloring systems and methods include a reservoir that holds a colorant. A vibrator motor is attached to the reservoir and applies a vibration to the reservoir to cause the colorant to collect at a bottom of the reservoir. An auger moves the colorant from the reservoir to an outlet.

The disclosure relates to a coating apparatus for applying a layer of particles to a receiving surface. The apparatus comprises a pressurized air source, an application chamber partially bounded by the receiving surface into which an air stream is delivered by the air source, an air return path for returning air from the application chamber to an intake of the air source to form an air circulation loop, a dosing device for introducing particles to be coated onto the receiving surface into the air circulation loop, and a controller serving to regulate the dosing device so as to maintain the particle concentration within predetermined limits. A method of applying a layer of particles is also provided, as well as printing systems benefiting from the present coating apparatus.
