Title: Safety device of a carding machine provided with a pair of crushing rollers

Abstract: Safety device of a carding machine provided with a pair of crushing rollers wherein a scraping plate is urged to the cylindrical surface of each crushing roller for the entire length thereof. Each scraping plate is turnably supported by a pin so that it can be moved away from the corresponding crushing roller when required. The turning motion of each scraping plate away from or toward the corresponding crushing roller, can be carried out simultaneously by means for setting the position of each scraping plate and a manually operable handle which actuates the setting means. The main driving motor of the carding machine is connected, in series with a main switch and a control switch, to an electric source. The control switch is closed when the handle is operated so as to fix the scraping plates in contacting condition with the corresponding crushing rollers and, on the other hand, the control switch is opened when the scraping plates are moved away from the corresponding crushing rollers.
