Buckle chute folder with clamp

摘要: A folder suitable for automatically folding successive sheets of paper, such as engineering drawings, by conveying them into a pocket to various distances depending upon where the fold is be formed. To arrest sheet at proper position in pocket, photosensor senses when leading edge has reached reference and, advanced further desired position, solenoid-operated clamp actuated move transversely and momentarily while being made. The amount which advances beyond controlled producing an electrical pulse each time conveyor moves predetermined amount, counting these pulses cause count corresponding been accumulated.
