Abstract (en)
[origin: EP1178120A2] In an apparatus for removable fastening of flat articles (2) to a work surface (1) for a machine for processing flat articles, e.g. leathers, the work surface (1) includes a plurality of fastening elements (3), which are selectively connected to suction means by respective valve means (10) to set under a vacuum effect the articles (2). Each of the valve means (10) includes a throttle valve (12), operated by a direct-current motor (21). The apparatus includes also sensor means (23) for detecting the motor (21) supply voltage and detecting variations with respect to the nominal voltage due to the motor rotation. Furthermore, the apparatus includes a sensor (24) detecting the current flowing through the motor (21) for detecting a motor (21) stop situation which is a consequence of reaching one of the extreme positions full open (A) and full closed (B) by the throttle valve (12). <IMAGE>
