Abstract

A multifunction static device for industrial sewing machines of the type comprising a foot-holder bar (2), fixed to which is a presser foot (3)', and a needle (4) moved by a needle-holder bar (.5), said device being characterized in that it substantially comprises a thin shaped tube (1), made of material resistant to impact and to wear, such as for example stainless steel, which is firmly constrained to said foot-holder bar (2) and envisages a bottom end (7) set alongside the needle (4) and facing in a direction transverse thereto in order to cool it during its axial movement, as well as a top end (14), which is connected to a compressed-air system of the production line or to another compressed-air sources, wherein the air delivered by the bottom end (7) of the tube (1) is managed and regulated by two purposely provided solenoid valves: a first solenoid valve is designed to activate/deactivate the emission of air for cooling the needle (4).during execution of the sewing operation, whilst a second solenoid valve is designed to activate/deactivate the emission - from the same bottom end (7) of said tube (1) - of an appropriate jet of air after the end of the sewing operation and/or of an appropriate jet of air immediately before start of the sewing operation to perform a thread-wiper function; for said purpose, the position of the bottom end (7) of the tube (1) is located at a height that substantially corresponds to the eye of the needle (4) when it is in the top resting position, or else immediately below the eye of the needle.
