PCT No. PCT/IB96/00760 Sec. 371 Date Feb. 2, 1998 Sec. 102(e) Date Feb. 2, 1998 PCT Filed Jul. 30, 1996 PCT Pub. No. WO97/05316 PCT Pub. Date Feb. 13, 1997A method for sewing leather articles includes positioning one edge of a first article (8) and one edge of a second article (9) to be sewn together against respective flat side surfaces (7a,7b) of a longitudinal guiding plate (7) formed at the top of a ring-like block (11). The ring-like block (11) rotates on a pin (12) that is supported, with horizontal axis and perpendicular to said guiding plate (7), by a free end of an arm (13) that swings with respect to a stationary support frame (2). The edges of the articles (8,9) are sewn together by means of an arc-shaped needle (6), which is reciprocated on a plane transversal to the guiding plate (7), between a retracted position, in which the needle is located beside one of said flat side surfaces (7b) and a piercing position, in which the needle pierces said articles (8,9); the needle (6) is moved forward and backward according to a predetermined step. Sewing of said articles (8,9) is followed by swinging said arm (13) together so that spatial attitude of the guiding plate (7) is kept unchanged as the sewing progresses.
