Abstract: The disclosure provides abrasive rotary tools with enhanced adhesion of an abrasive layer. Exemplary abrasive rotary tools include a securing element configured to secure an abrasive layer to an abrasive rotary tool. The securing element may be positioned over a portion of the abrasive layer, such as a tab or end, such that repeated forces on the abrasive layer do not decouple the abrasive layer from the rotary tool. In this way, an abrasive rotary tool may maintain a contact surface integrity through repeated use for extended life of the rotary tool.

Abstract: Methods and apparatuses for roll coating are provided. The roll coating system (100) includes a coating roll (110) having a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14), the inner layer being softer than the outer layer. A substrate (3) is conveyed to the nip (12) between the coating roll and a back-up roll (120). A metered coating material is transferred from the coating roll to a patterned surface structure (40) of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.

Abstract: A printing system is provided. The printing system (300) includes a printing roll (310) having a rigid printing pattern (312) on a surface thereof configured to receive an ink material (330); and an inking roll (320) positioned adjacent to the printing roll. The inking roll includes an elastically deformable surface and a number of cells (324) disposed on the elastically deformable surface. A method of printing is also provided. The method includes (a) inking at least a portion of a rigid printing pattern (312) on a surface of a printing roll (310) by contacting the rigid printing pattern with an inking roll (320); and (b) contacting the rigid printing pattern with a substrate (350), transferring the ink material from the rigid printing pattern to a surface of the substrate. Printing systems and methods can achieve higher printing feature resolutions than typically achievable via flexographic printing.

Abstract: According to one embodiment, a method of making an abrasive layer on a backing is disclosed. The method can comprise: providing a distribution tool having a dispensing surface with cavities, providing a backing having a first major surface, supplying magnetizable abrasive particles to the dispensing surface such that at least one of the magnetizable abrasive particles is disposed in a respective one of the cavities, applying a magnetic field to retain the magnetizable abrasive particles disposed in the cavities, aligning the backing with the dispensing surface with the first major surface facing the dispensing surface, transferring the magnetizable abrasive particles from the cavities to the backing, sequent to or simultaneous with transferring the abrasive particles, removing or changing a magnetic field so the magnetic field no longer retains the magnetizable abrasive particles in the cavities.

Abstract: A method of tuning the contact pressure across an abrasive disc is presented. The method includes coupling the abrasive disc to a backup pad comprising a pressure tuning feature that causes an experienced pressure by a worksurface, across a radius of the abrasive disc, to be uniform. The method also includes abrading a worksurface by contacting the abrasive disc to the worksurface. The backup pad causes the abrasive disc to have a cut rate that is substantially uniform across the surface of the abrasive disc when compared to the abrasive disc on a backup pad with no pressure tuning feature.

Abstract: Methods and apparatuses for applying coatings on a moving web are provided. A slot die including a concave die lip coating surface and a back-up roll engage with each other. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.

Abstract: The disclosure is generally directed to a method of manufacturing an abrasive rotary tool using a molded elastic layer. A mold includes a cavity with a peripheral surface. An abrasive sheet is positioned so that a working surface of the abrasive sheet is positioned along at least a portion of the peripheral surface. A spindle is positioned within the mold to create a region between the spindle and the abrasive sheet. An elastomeric precursor material is injected into the region and solidified to form an elastic layer. As a result, the elastic layer is in direct contact with at least a portion of the opposed surface of the abrasive sheet and at least a portion of the exterior surface of the spindle. In this way, an abrasive rotary tool may be manufactured without using adhesive layers and/or fastening means.

Abstract: A printing system (200) including a printing roll (220) is provided. The printing roll (220) includes an elastically deformable and compressible inner layer (224) and a thin outer shell (222) to cover the inner layer (224). The thin outer shell (222) includes a pattern of raised print features (223) to receive ink material thereon. The inner layer (224) is softer and thicker than the thin outer shell (222), and optionally, the thin outer shell (222) is removable from the inner layer (224). The inner layer (224) of the printing roll (220) has a thickness, a compression force deflection value and an elastically-deformable compressibility such that the raised print features (223) of the printing roll (220) do not slide or deform with respect to the printed web (2) in an amount to generate a substantially visible dot gain.
