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