A piece of foam plastic is introduced into a pocket of a life jacket fitted to it and made of flexible material, through an opening formed at the edge of the pocket. The circumference of the opening is shorter than the circumference of the piece of foam plastic. The piece of foam plastic is compressed between two arms in a U-shaped manner and then further compressed until the legs close. The pocket with the extended opening at its front is pushed over the bent piece of foam plastic. The arms, insofar as the opening permits, are spread apart. The pocket together with the piece of foam plastic located therein are pulled off of the two arms. The opening is then sewn up. |
