Apparatus for stably transferring belt-like material

An apparatus for stably transferring belt material comprising:

• supplying means for supplying belt material;
• first absorbing and feeding means having a reserving chamber for continuously absorbing and feeding said belt material supplied from said supplying means, and a pressure detecting chamber, provided at the back of said reserving chamber through a through hole, and closed to detect its internal pressure;
• transferring means for pulling out said belt material absorbed and fed to the reserving chamber of said first absorbing and feeding means so a to be transferred;
• first pressure converting means, connected to said pressure detecting chamber of said first absorbing and feeding means, for detecting the internal pressure of said pressure detecting chamber changing in accordance with the amount of absorbing and feeding belt material absorbed and fed to said reserving chamber so as to convert said detected internal pressure to an electrical signal;
• supply controlling means for controlling the amount of supply of the belt material supplied by supplying means based on the electrical signal converted by said first pressure converting means;
• second absorbing and feeding means having a reserving chamber for continuously absorbing and feeding said belt material transferred from said transferring means, and a pressure detecting chamber, provided at the back of said reserving chamber through a through hole, and closed to detect its internal pressure;
• receiving means for receiving said belt material transferred to said reserving chamber of said second absorbing and feeding means;
• second pressure converting means, connected to said pressure detecting chamber of said second absorbing and feeding means, for detecting the internal pressure of said pressure detecting chamber changing in accordance with the amount of absorbing and feeding the belt material absorbed and fed to said reserving chamber so as to convert said detected internal pressure to an electrical signal;
• and
• receiving controlling means for controlling the amount of receiving of the belt material received from said receiving means based on the electrical signal converted by said second pressure converting means.
