Abstract
Process of manufacturing a papermakers' wet press felt for the wet end and a felt produced thereby with one or two flaps (14, 10), made of two batts (12, 13) needled onto each side of the felt (1), which ends in two rows of loops (4, 5) that are intended to seam the felt, characterized in that the rows of loops (4, 5) are joined during needling by temporary, removable connecting means (6) placed in relation to the flap(s) (14, 16) which have a greater width than the widths of the finally cut flaps (14, 16). The flap(s) (14, 10) are not damaged during the needling operation and are easily loosened without damage by removing the spiral (7) which form the temporary joining means (6).
