  • Patent number: 9833965
    Abstract: In a sealed letter producing device which folds and seals, with a content, an envelope sheet on which pressure-sensitive adhesives are provided, sealing with pressure rollers smaller than in conventional rollers is achieved. Pressure-sensitive adhesives 106 are provided in both edge portions in the width direction of an envelope sheet 100, and remoistening paste 107 is provided inwardly of both edge portions. The remoistening paste is moistened when the envelope sheet wrapping a content is bent and formed into an envelope 50, the entire surface of the envelope is pressurized by low-pressure rollers and adhered with the remoistening paste, and further only both edge portions of the envelope 50 are pressurized by an upper and lower set and a left and right pair of the pressure rollers 80, 80 having a small width to adhere the pressure-sensitive adhesive 106.

  • Patent number: 9296520
    Abstract: Another coating part is formed along a sheet short side direction, on a region which is a part of an envelope outer side of a third component sheet and which contacts a flap by folding along a second folding line. A first cutout part and a second cutout part which respectively extend in an extension direction of a first coating part and a second coating part, are respectively formed on both side fringes in the sheet short side direction in the third component sheet. The minimum width of each of the first cutout part and the second cutout part in the sheet short side direction is set longer than a length from the side fringe of the envelope sheet in the sheet short side direction to the inner side fringe of each of the first coating part and the second coating part.

  • Patent number: 9283803
    Abstract: A sealed letter forming apparatus has a sheet feed unit containing an envelope sheet to be an envelope and a content sheet to be a content; a printer for printing on the respective sheets supplied from the paper feed unit; an enclosing and sealing unit for folding the respective sheets printed by the printer, and enclosing and sealing the respective sheets; and a controller to control the enclosing and sealing unit to stop the sealed letter forming processing when an error related to the envelope sheet or the content sheet in an n-th article occurs, and to perform the sealed letter forming processing without sealing a sealed letter of the n-th article as a sealed letter to be checked by a user when the error is canceled. A sealed letter forming processing is performed on each article which is a combination of the envelope sheet and the content sheet.

  • Patent number: 9139338
    Abstract: The envelope sheet includes a first area provided with a flap, a second area extended from the first area with interposing a first fold line, a third area extended from the second area with interposing a second fold line, and an adhesive pasted area formed on the third area and extended along a direction perpendicular to a feed direction. The envelope sheet is configured to be, in a stuff and seal apparatus, preliminarily folded at the second fold line while a content is stuffed thereinto, and then fed forward together with the content by at least two pairs of the feed rollers. A length of the third area along the feed direction is made equal-to or longer-than a distance between the two pairs of feed rollers. According to the envelope sheet, the content can be prevented from being inadequately stuffed into an envelope transformed from the envelope sheet.

  • Publication number: 20150135642
    Abstract: A glue application unit applies glue to glue application region of an envelope form to form main adhesive part with a required thickness that allows firm adhesion between glue application region and counter region after the sheet adhesion process, and a temporary adhesive part with a thickness thinner than the main adhesive part for temporarily adhering the glue application region and the counter region within a short period of time. A predetermined pressure is applied to the glue application region and the counter region which are in contact with each other on the envelope form having a content enclosed so that those regions are adhered by the sheet bonding unit.

  • Publication number: 20140187400
    Abstract: An enveloping machine includes a first feed path for feeding an envelope sheet, a second feed path for feeding a content sheet, a feed roller mechanism disposed on the first feed path and provided with nip rollers for feeding the envelope sheet, an insertion and seal unit disposed downstream from a confluent point of the first and second feed paths for inserting the content sheet into the folded envelope sheet and then sealing the folded envelope sheet, a position correction unit disposed upstream from the confluent point for correcting a lateral position of the envelope sheet, and a controller. The controller controls the feed roller mechanism to hold the envelope sheet by the nip rollers, and concurrently controls the position correction unit to shift the envelope sheet laterally to a predetermined lateral position. According to the enveloping machine, time required for position correction of the envelope sheet can be shortened.
