PURPOSE:To easily form a slit penetrating through a bonded fixing part of a hollow yarn membrane by previously arranging a scarcely adhesive flexible body which has been formed to a same shape as a desired slit to the part for bonding, then removing the flexible body after curing the charged adhesive. CONSTITUTION:A flexible body 2, such as polystyrene foam, comprising a scarcely adhesive material to an adhesive material to be used for bonding, formed to a same shape as a desired slit 7, is previously arranged together with a hollow yarn bundle 3 in a case 1. The adhesive material 6 is charged from a vessel 4 through a hose 5 into the case 1 and a bonded part is formed by the centrifugal bonding method. The flexible body 2 alone is removed from the bonded part after the adhesive material is cured. Thus, a slit 7 is formed to the part left after removal of the flexible body 2.
