Abstract

The patent is intended for the field of leather processing technology for making shoes, clothing and other purposes. Flat belt (1) serves to insert leather into the machine. Belt rotation is carried out through rollers (3, 4, 5 and 6). Pneumatic cylinder (2) pressured by leather moves downwards, thus making up for the difference in leather thickness. Pressure regulator (7) allows changing of the pressure in the lower part of the cylinder (2) which results in changing the resistance. Manometer (8) shows the pressure and makes it possible to determine the absolute resistance. Pneumatic unit has been adjusted for the installation onto any so far produced machine type, hence for the installation onto any machine produced at present.
