摘要： Methods and apparatuses for applying coatings (9) on a moving web (3) are provided. A slot die (20) and a back-up roll (11) engage with each other. The back-up roll has a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14). 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.

摘要： According to one embodiment, a method of making an abrasive layer on a backing is disclosed. The method can comprise: providing dispensable magnetizable abrasive particles and a distribution tool, wherein the distribution tool is configured to receive the magnetizable abrasive particles therein, and wherein the distribution tool is configured to impart at least one of a predetermined orientation and alignment of the magnetizable abrasive particles, positioning a backing adjacent to the distribution tool and spaced therefrom by a gap, applying a magnetic field to at least the backing and a portion of the gap between the backing and the distribution tool, and transferring the magnetizable abrasive particles from the distribution tool to a first major surface of the backing, wherein the magnetic field is applied during the transfer of the magnetizable abrasive particles.

摘要： Methods and apparatuses for applying coatings on a baggy web are provided. A Mayer rod and a back-up roll engage with each other to form a nip. The back-up roll has a deformable inner layer with a surface thereof covered by a deformable outer layer. The Mayer rod and the flexible web at a contacting area are impressed into the back-up roll with a machine-direction nip width W and a nip engagement depth D, which enables formation of a coating having a substantially uniform thickness.

摘要： A powder-rubbing apparatus comprises: a rotatable rubbing roll having a rotational axis; a substrate path; an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis; and a powder coating die comprising an inlet port in fluid communication with an outlet port disposed adjacent to the substrate path. The substrate frictionally contacts the rotatable rubbing roll within a rubbing zone. A dispenser for dispensing gas-borne powder is in fluid communication with the inlet port of the powder coating die. The dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone. A method of using the powder-rubbing apparatus and a powder-rubbed web preparable thereby are also disclosed.
