A pair of interleaved synthetic-resin coils are separated upstream of the sewing station of a sewing apparatus, then both coils are sewn to respective support tapes, and finally the two coils, with attached tapes, are interleaved again just downstream of the sewing station. The sewing station can include a pair of plates defining a Y-shaped channel which serves to hold the coils and tapes during sewing and to mesh them together immediately afterwards. |
