Abstract
A scraper central portion in which a first contact surface has a trapezoidal shape with a lower base longer than an upper base, and scraper end portions that extend and are bent from respective lateral sides of a trapezoidal shape of the scraper central portion to a side of the first contact surface, and that include second contact surfaces that come in contact with the coating material. A lower base of the scraper central portion and lower sides of the scraper end portions are on the same plane. In a state where the first contact surface is vertical to the surface of the screen plate, the lower base of the scraper central portion and the lower sides of the scraper end portions come in contact with the coating material on the surface of the screen plate, and slide on the surface of the screen plate.
Claims8
A scraper for a screen printing device that slides in a predetermined direction over a surface of a flat screen plate on which a coating material is supplied to coat the coating material on the surface of the screen plate, the screen printing device scraper comprising:
- a scraper central portion in which a first contact surface that comes in contact with the coating material has a trapezoidal shape with a lower base longer than an upper base;
- and
- scraper end portions that extend and are bent from respective lateral sides of a trapezoidal shape of the scraper central portion to a side of the first contact surface, and that include second contact surfaces that come in contact with the coating material, wherein
- a lower base of the scraper central portion and lower sides of the scraper end portions are on a same plane, and
- in a state where the first contact surface is vertical to the surface of the screen plate, the lower base of the scraper central portion and the lower sides of the scraper end portions come in contact with the coating material on the surface of the screen plate, and slide on the surface of the screen plate.
