SYSTEMS AND METHODS FOR MAKING ABRASIVE ARTICLES

Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool including a plurality of walls defining a plurality of slots. Each slot 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 and moving relative to the tool. At least a majority of the particles distributedfrom the tool undergo an orientation sequence in which each particle first enters one of the slots. The particle then passes partially through the slot such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the slot. The sequence then includes the particle remaining in simultaneous contact with one of the walls and the major face for a dwell period while the web moves relative to the tool. 本发明公开了制造磨料制品的方法。将磨料颗粒加载至分配工具，所述分配工具包括限定多个狭槽的多个壁。每个狭槽向所述工具的下侧敞开。所述加载的颗粒从所述分配工具分配到背衬幅材的主面，所述背衬幅材在所述下侧的下方并相对于所述工具移动。从所述工具分配的所述颗粒中的至少大部分经历定向顺序，在所述定向顺序中每个颗粒首先进入所述狭槽中的个狭槽。然后所述颗粒部
