PRODUCTION OF STRIPED COATINGS ON STRIP

摘要

An apparatus and method for producing a striped coating on a continuous moving strip. The apparatus has a smoothing device including a doctor roll (4) forming a nip with the strip (5). A stationary partition means (8) is provided dividing the nip into nip lengths. Upstream of the smoothing device (4, 5) is a means to deposit coating materials on the strip (5) for delivery into the respective nip lengths at predetermined rates. The deposit means maintain a bead (9) of coating material in each nip length and a stripe of coating material is formed on the strip from coating material escaping the respective nip length as the strip (5) passes through the nip.
