Abstract (en)
[origin: EP0081614A1] 1. An automatic silk-screen printing machine including means for synchronized control of movements comprising a relative linear movement of the screen in comparison with a doctor blade, a downward movement of the doctor blade and a simultaneous upward movement of the member which holds the object, in which the mechanism for moving the doctor blade holder (14) downwards and upwards includes an electro-magnet which controls the downward movement of the doctor blade and an arm (15) pivoting at a fixed point (16) in comparison with the means for linearly moving the doctor blade, characterized by a return spring (18) of said arm to a position corresponding to the up position of the doctor blade, by a member (17) having an abutment surface above said arm, by means (23) for applying a downward vertical pressure onto said abutment surface ; a link (19) having a pivot pin (190) integral with said arm and holding at its end the axle of a wheel (191) bearing against said abutment surface, a rod (20) connected to one end of said link so as to cause it to oscillate about its pivot pin and said electromagnet (21) which has a movable member integral with the opposite end of said rod and means for causing energization of the electromagnet throughout the printing period.
