Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
A paper folding apparatus for folding continuous paper correspondingly to the folded length thereof and piling the folded paper, having width guide members disposed in opposed relationship with each other on the uppermost surface of the sides of the folded continuous paper for guiding the widthwise inclination of the paper into a predetermined area, pivot shafts provided in the lower portions of said width guide members, swinging means for causing the upper portions of said width guide members to swing about said pivot shafts, vertically moving means for moving said width guide members upwardly or downwardly following the uppermost surface of the folded continuous paper moved upwardly or downwardly correspondingly to the folded width dimension of the continuous paper, and horizontally moving means for parallel-moving at least one of the opposed width guide members leftwardly or rightwardly to a position corresponding to the width dimension of the continuous paper, said swinging means of said width guide members, said vertically moving means and said horizontally moving means being driven independently of one another.
