Abstract: This invention provides a pressure sealer apparatus, for folding and sealing papers coated with adhesion at part of margins thereof into a smaller size, comprising: a buffer, controlled by a buffer motor and a buffer switch to move between an inactivated and an activated position; a paper entry provided at a downstream of the buffer; a paper alignment provided at a downstream of the paper entry, including an alignment roller set and a ball set, the ball set having a ball freely rotatable in a frame and suspended above the alignment roller set; a folding device provided at a downstream of the paper alignment; a presser provided at a downstream of the folding device, including a pressure cylinder situated to form an angle with respect to the alignment roller; and an exit provided at a downstream of the presser.
