发明名称 Steel reinforced concrete bending machine
摘要 <p>The contactor is controlled via an electrical step-up switch which regulates an impulse counter (1) or connects relays (2) in series. Impulses corresponding to the main bending angles can be preset in advance. (1) or (2) are connected to a source of impulse operated by adjustors. The drive motor is switched off after a predetermined number of impulses is reached.</p>
