Title:
繊維を配列するための方法と装置
Document Type and Number:
Japanese Patent JP4615717
Kind Code:
B2
Abstract:
Magnetizable fibers dispersed in a viscous body, particularly reinforcing metal fibers dispersed in a wet cementitious material, is carried out by providing a fiber aligning member (15) having a nonmagnetic wall (17) including a first wall portion (17A) and a second wall portion (17B), moving the aligning member (15) relative to the viscous body with the first wall portion (17A) leading and the second portion (17B) trailing it and with the first and second wall portions (17A, 17B) contacting the viscous body, and directing a magnetic field into the viscous body through the first wall portion (17A) to subject the fibers (F) to a moving magnetic field. A device for performing the method comprises: a fiber aligning member (15) having a nonmagnetic wall (17) including a first wall portion (17A) and a second wall portion (17B); and a magnet device (18) disposed adjacent the first wall portion (17A) for directing a magnetic field into the viscous body through the first wall portion (17A), and a manipulating device (14) for moving the fiber aligning member (15) relative to the viscous body with the first wall portion (17A) ahead of the second wall portion (17B) and with the first and second wall portions (17A, 17B) contacting the viscous body.
