A belt-like material stably transferring apparatus comprises an absorbing and feeding apparatus (40) for continuously absorbing and feeding the belt-like material by use of a difference in air pressure. The absorbing and feeding apparatus (40) comprises a reserving chamber (40a) for absorbing and feeding the belt-like material (1) to be reserved therein, and a pressure detecting chamber (40b) connected to the reserving chamber (40a) through a slit (40c). The reserving chamber (40a) has an opening portion for feeding the belt-like material (1), and blowers (14, 36) are connected at a position, which is opposite to the opening portion. The pressure of the pressure detecting chamber (40b) is changed in accordance with the change of the pressure in reserving chamber (40a) connected to the pressure detecting chamber (40b) through the slit (40c). The pressure of the reserving chamber (40a) is changed in accordance with the amount of absorbing and feeding the belt-like material (1) absorbed and fed to the reserving chamber (40a). Due to this, the pressure of the pressure detecting chamber (40b) is detected by pressure detectors (50, 60), thereby the amount of absorbing and feeding the belt-like material (1) absorbed and fed to the reserving chamber (40a) is detected. The belt-like material stably transferring apparatus comprise analog card for controlling the amount of supplying the belt-like material (1) based on the amount of absorbed and fed belt-like material (1). <IMAGE> |
