Definitions
- the subject of the present invention is a method of assembling by sealing sheets of paper, in particular a sheet of paper folded back on itself and intended for games of chance or the like, as well as the device allowing its implementation.
- This method also has the drawback of being relatively expensive since it requires the edge of the sheet to be glued before it is perforated.
- the object of the present invention is to provide a inexpensive assembly process which makes it possible to obtain an effective and irreversible sealing of a sheet of paper folded back on itself.
- the assembly method according to the invention consists in producing on the edges of a sheet of paper previously folded back on itself two series of parallel tabs which interpenetrate in thickness and offset one with respect to the other so to create together an approximately continuous seal.
- the interpenetration in thickness of the tabs results in an effective and irreversible joining of the thicknesses of the paper sheet.
- This joining is obtained, according to the invention, by means of tongues whose edges parallel to those of the sheet result from a straight cut, but whose end results from tearing off the paper.
- tongues are produced, in accordance with the invention, by means of prismatic perforation teeth machined on a wheel, at the rate of two perforation rings per wheel, these perforation rings cooperating with a counter-tool consisting of three parallel discs separated by two spacers and whose spacing is equal to the width of the perforation teeth.
- the device allowing the implementation of the method according to the invention is essentially characterized in that it comprises two sets of wheels movable in rotation, each wheel comprising two perforation rings provided with perforation teeth having approximately the shape of a prism with a triangular base, the perforation teeth being inclined relative to the spokes of the wheel in the direction of rotation of the latter and operating between three parallel discs carried by a wheel serving as a counter-tool and separated from each other by a space equal to the width of the perforation teeth.
- the thicknesses of paper inserted between the latter and the wheels carrying the perforation crowns are cut in the form of tongues whose edges parallel to those of the sheet, result from a clean cut but whose end results from tearing off the paper.
- the perforation teeth cooperating with the discs serving as a counter-tool make lateral clear cuts but perform between the discs, and due to the absence at this location of cutting counter-surface, tearing off the paper on a length corresponding to the length of the end of the puncture teeth.
- the perforation rings 2 and 3 are inserted between three discs 5, 6, 7 machined on a wheel 8 serving as a counter-tool.
- the opening of the sealed sheet thus obtained causes a separation by tearing off the tabs which makes it completely impossible for a subsequent separation.
