ABSTRACT:
A method for handling and sewing the perimeter of upholstered articles, in which the upholstered article is fed through the sewing machine on a table with a sliding surface in one of whose sides the said sewing machine is fixed, which is characterized by having some pusher elements which protrude from the plane of the table through some longitudinal and circumference arch shaped grooves, which are driven from the lower part of said table. The longitudinal pushers assist the linear feed of the upholstered article until its corner reaches the height of the sewing machine, when they withdraw to their initial position, at the same time as the turning pushers start to work. These turning pushers make the upholstered article turn, describing a circumference arch path of ninety degrees, while the head of said sewing machine sews the corner of said upholstered article in a synchronized manner. When the turn has been completed, the turning pushers withdraw to their initial position and the previous longitudinal pushers start to work.
