Abstract (en)
[origin: WO2017187465A1] A device of control of the length of needleful in sewing machines (1) with running stitch comprising a series of sensors and/or detecting elements (7), which are placed at a path portion that follows the thread (4) on a mobile portion (8) of the recovery wheel (9) of the thread (4) of the sewing machine (1) and which are configured to detect said thread (4); the sensors and/or detecting elements (7) are also interfaced with a digital signal amplifier, which is in turn connected with a PCB provided with a software program suitable to correlate the presence of the thread (4) at the mobile portion (8) of the recover wheel (9) with an angular measure of rotation of said recovery wheel (9), in order to signal at least one stretch of remaining needleful and/or to suggest the insertion of one or more needlefuls and/or to signal breaks of one or more needlefuls.
