<p>The present invention concerns an equipment (1), and the relative method, for realizing the seam of staggered pockets overlapped in a wallet or document case with a sewing machine. The sewing machine is provided with a sewing head (2) and a sewing plane (14) which is mobile with respect to the sewing head and on which two or more sheets in material to be sewn can be arranged. According with the invention the equipment comprises an arrangement (5, 6,7,9,15) configured to be applicable in an integral manner to the sewing plane (14) of the sewing machine. The said arrangement comprises a blocking unit (5,6,7), mobile, when in use, with respect to the sewing plane (14) between a lifted position from the sewing plane (14) and a lowered position substantially in contact with the sewing plane and further translatable in parallel with respect to the sewing plane. In this manner, in correspondence of the lowered position, the blocking unit results arranged on the sewing plane, blocking the sheets in material to be sewn and, following the return in lifted position at the end of the sewing, the unit translates in such a way as to allow the subsequent block of a further sheet to be overlapped to the previously seamed ones.</p> |
