The present invention discloses a method for manufacturing an eyelet (10) for a tarpaulin (50), the eyelet having upper and lower eyelet bodies (20,30) each provided with a plurality of fixing protrusions (40) formed in a shape of concentric circles on one surface thereof in such a manner that the plurality of fixing protrusions (40) formed on the upper eyelet body (20) confront to the plurality of fixing protrusions (40) formed on the lower eyelet body (30), the method comprising the following steps of: a step of positioning the upper and lower eyelet bodies (20,30) by using a conveying means in such a manner as to place the tarpaulin (50) there between; a step of punching a given position on the tarpaulin fabric (50) by means of a punching machine with an integrally-formed ultrasonic horn; a step of conveying the upper and lower eyelet bodies (20,30) to a position of the ultrasonic horn and fusing the upper and lower eyelet bodies (20,30) to the tarpaulin (50) through the compression of the ultrasonic horn; a step of fusing a protruded part (31) extending upwardly from the circumference of a through-hole (21) of the lower eyelet body (30) by compression in the ultrasonic-fusing step to form an inner circumferential edge part; and a step of passing a rope (60) through the through-hole (21) of the eyelet (10) mounted on the tarpaulin (50). |
