2019 AUG 14 (NewsRx) -- By a News Reporter-Staff News Editor at Daily Asia Business -- From Alexandria, Virginia, NewsRx journalists report that a patent by the inventors Oda, Shuji (Tokyo, Japan); Dangami, Akira (Tokyo, Japan), filed on December 5, 2016, was published online on August 12, 2019.

The patent’s assignee for patent number 10,364,115 is Lintec Corporation (Tokyo, Japan).

News editors obtained the following quote from the background information supplied by the inventors: “A sheet sticking apparatus configured to fold an adhesive sheet, in which a feeding-direction rear end of a first sheet is connected to a feeding-direction leading end of a second sheet, and stick the adhesive sheet to an adherend has been typically known (see, for example, Document 1: JP-A-2006-160328).

“However, the typical sheet sticking apparatus of Document 1 described above has the following disadvantage. When an adhesive sheet to be stock to an adherend includes a first sheet PS1 and a second sheet PS2 having a feeding-direction leading end PS21 temporarily attached to a feeding-direction roar end PS11 of the first sheet PS1 as shown in FIG. 5A, the feeding-direction leading end PS21 of the second sheet PS2 may not be released from the feeding-direction rear end PS11 of the first sheet PS1 as shown in FIG. 5B. Accordingly, the feeding-direction leading end PS21 of the second sheet PS2 may not be stuck to the adherend.”

As a supplement to the background information on this patent, NewsRx correspondents also obtained the inventors’ summary information for this patent: “An object of the invention is to provide a sheet sticking apparatus and a sheet sticking method capable of sticking an adhesive sheet including a first sheet and a second sheet having a feeding-direction leading end temporarily attached to a feeding-direction roar end of the first sheet to an adherend while exposing a surface of the feeding-direction leading end of the second sheet facing the first sheet.

“A sheet sticking apparatus according to an aspect of the invention includes: a feeder configured to feed an adhesive sheet; a folding unit configured to fold the fed adhesive sheet; and an attaching unit configured to press the folded adhesive sheet onto an adherend to stick the adhesive sheet to the adherend, wherein the adhesive sheet includes a first sheet and a second sheet having a feeding-direction leading end temporarily attached to a feeding-direction rear end of the first sheet, and the folding unit includes a deflecting section configured to deflect the second sheet into a reverse V-shape and release the feeding-direction leading end of the second sheet from the feeding-direction rear end of the first sheet so that a surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed by the deflecting section and the adhesive sheet is folded.

“In the above arrangement, the deflecting section includes a drive roller driven by a drive unit and a pinch roller configured to pinch the adhesive sheet in cooperation with the drive roller, the drive roller and the pinch roller stop flow of the feeding-direction leading end of the second sheet while the feeder feeds the adhesive sheet to deflect the second sheet into the reverse V-shape, and the adhesive sheet in which the surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed passes through a space between the drive roller and the pinch roller so that the adhesive sheet is folded.

“A sheet sticking method according to an another aspect of the invention includes: feeding an adhesive sheet, the adhesive sheet including a first sheet and a second sheet having a feeding-direction leading end temporarily attached to a feeding-direction rear end of the first sheet; folding the fed adhesive sheet, the folding comprising deflecting in which the second sheet is deflected into a reverse V-shape and the feeding-direction leading and of the second sheet is released from the feeding-direction rear end of the first sheet and a surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed before the folding of the fed adhesive sheet; and pressing the folded adhesive sheet onto an adherend to stick the adhesive sheet to the adherend.

“According to the above aspects of the invention, when the adhesive sheet to be stuck to the adherend includes the first sheet and the second sheet having the feeding-direction leading end temporarily attached to the feeding-direction rear end of the first sheet, since the second sheet is deflected into a substantially reverse V-shape, the feeding-direction leading and of the second sheet is deformed to be raised up from the feeding-direction rear end of the first sheet. Accordingly, the feeding-direction leading end of the second sheet can be released from the feeding-direction rear end of the first sheet, and the adhesive sheet can be stuck to the adherend while the surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed.

“When the deflecting section includes the drive roller and the pinch roller, it is possible to release the feeding-direction leading end of the second sheet from the first sheet with a simple structure and fold the adhesive sheet in which the surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed.”

The claims supplied by the inventors are:

“What is claimed is:

“1. A sheet sticking apparatus comprising: a feeder configured to feed an adhesive sheet; a folding unit configured to fold the fed adhesive sheet; and an attaching unit configured to press the folded adhesive sheet onto an adherend to stick the adhesive sheet to the adherend, wherein: the adhesive sheet includes (i) a first sheet and (ii) a second sheet having a feeding-direction leading end temporarily attached to a feeding-direction rear end of the first sheet, and the folding unit includes a deflecting section configured to deflect the second sheet into a reverse V-shape and release the feeding-direction leading end of the second sheet from the feeding-direction rear end of the first sheet wherein a surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed by the deflecting section and the adhesive sheet is folded.

“2. The sheet sticking apparatus according to claim 1, wherein: the deflecting section includes (i) a drive roller driven by a drive unit and (ii) a pinch roller to pinch configured to pinch the adhesive sheet in cooperation with the drive roller, the drive roller and the pinch roller stop flow of the feeding-direction leading end of the second sheet while the feeder feeds the adhesive sheet to deflect the second sheet into the reverse V-shape, and the adhesive sheet, in which the surface of the feeding-direction leading end of the second sheet facing the first sheet is exposed, passes through a space between the drive roller and the pinch roller so that the adhesive sheet is folded.”
