Patent number: 9833965Abstract: 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.Type: GrantFiled: October 26, 2011Date of Patent: December 5, 2017Assignee: RISO KAGAKU CORPORATIONInventors: Tadayuki Wakatabi, Yasuhiro Katada

Patent number: 9139338Abstract: 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.Type: GrantFiled: September 19, 2013Date of Patent: September 22, 2015Assignee: Riso Kagaku CorporationInventors: Tadayuki Wakatabi, Akinori Maekawa

Publication number: 20140187400Abstract: 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.Type: ApplicationFiled: December 26, 2013Publication date: July 3, 2014Applicant: Riso Kagaku CorporationInventors: Tadayuki WAKATABI, Toshio ENDOU, Yasuhiro KATADA, Akihiro TSUMURA
