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.

Abstract: A mail inserter for inserting a mail into an envelope having a flap and a throat, including: an envelope entry; an envelope carrier, provided downstream of the envelope entry; an envelope retainer, provided at the downstream of the envelope carrier; a mail entry, for advancing the mail into the mail inserter; a mail carrier, provided downstream of the mail entry; a sealer, provided downstream of the envelope retainer; wherein the envelope entry, envelope carrier, envelope retainer and sealer jointly form an envelope path, and the mail entry and, the mail carrier jointly form a mail path that merges into the envelope path after the mail carrier.

Abstract: A correspondence collator for collating at least one page of paper directly printed out from a printer in a regular order, including: a paper entry for advancing the page of paper into the correspondence collator; an organizer, provided downstream of the paper entry for flipping the page of paper end-to-end and upside-down; a paper carrier, provided downstream of the organizer, including: a chain carrying the flipped page of paper through the paper carrier; an optional folding device, and a mail exit, provided downstream of the paper carrier for discharging the page of paper from the correspondence collator; wherein the paper entry, organizer, paper carrier, optional folding device and mail exit jointly form a paper path
