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.
Claims9
A pressure sealer apparatus for folding and sealing papers coated with adhesion at part of margins thereof into a self-mailer, 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,
- wherein the buffer motor drives the buffer switch to move the buffer to the activated position during occurrences of paper jamming in the pressure sealer apparatus, and drives the buffer switch to move the buffer to the inactivated position after elimination of the paper jamming.
