    Abstract: Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool including a plurality of strips defining a plurality of channels. Each channel is open to a lower side of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side. At least a majority of the particles distributed from the tool undergo an orientation sequence in which each particle first enters one of the channels. The particle then passes partially through the channel such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the channel. The sequence then includes the particle remaining in simultaneous contact with one of the strips and the major face for a dwell period.

    Abstract: In methods and systems of making an abrasive article, abrasive particles are loaded to a distribution tool including a plurality of upper walls defining a plurality of spacing slots, and a plurality of lower walls defining a plurality of distribution slots. The spacing slots are open to the distribution slots, which are open to a lower side of the tool. The loaded particles are spaced and distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool in a machine direction. The upper walls space the particles in the machine direction. The particles distributed by the lower walls undergo an orientation sequence in which each particle is oriented into a column aligned along the machine direction. The upper walls can be disposed oblique to the lower walls. The upper and lower walls can have pointed upper portions.

    Abstract: A system includes a distribution tool, a backing, a first plurality of abrasive particles and a second plurality of abrasive articles. The distribution tool includes a first section and a second section. The first section is configured to receive the first plurality of abrasive particles and pass the first plurality of abrasive particles through one or more of the plurality of slots to the backing. The second plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the first plurality of abrasive particles. The second section is configured to receive the second plurality of abrasive particles and pass the second plurality of abrasive particles through one or more of the plurality of slots to the backing.
