Edge embosser set for tissue paper roll conversion

Abstract

An edge embosser for converting paper tissue, having three processing stations, two for engraving ( 1 ) and ( 2 ) and one for joining ( 3 ), between which there are continuous strips of ordinary paper, wherein (P 1 ) is a lower or inner strip and (P 2 ) is an upper or outer strip, so that they can both be embossed with any pattern in the two first stations ( 1 ) and ( 2 ), and then both are joined by their edges through station ( 3 ) forming a finished continuous strip of paper (P 3 ); each engraving station ( 1 and 2 ) comprises a pair of rolls, one made of rubber ( 4 A- 4 B) and the other of engraved steel ( 5 A- 5 B), where the latter are pulled by the corresponding continuous inner and outer strip of paper (P 1 or P 2 ) passing between each pair and guided by casters ( 6, 7, 8 and 9 ); said joining station ( 3 ) is placed after the two engraving stations ( 1 - 2 ), and it also comprises two rollers, a wheel roller ( 10 ) and a pulled counter-wheel roller ( 11 ), between which the continuous strips of paper (P 1 and P 2 ) are aligned, so that they can be joined by their edges and, thus, said wheel roller ( 10 ) presents, along its length, various rings ( 12 ) mounted on O-rings ( 13 ), each ring constituting the protruding means for supplementary pressure and the realization of the fastening bands by mechanical lamination (F).

1 . An edge embosser for converting paper tissue, having three processing stations, two for engraving ( 1 ) and ( 2 ) and one for joining ( 3 ), between which there are continuous strips of ordinary paper, wherein (P 1 ) is a lower or inner strip and (P 2 ) is an upper or outer strip, so that they can both be embossed with any pattern in the two first stations ( 1 ) and ( 2 ), and then both are joined by their edges through station ( 3 ) forming a finished continuous strip of paper (P 3 ); each engraving station ( 1  and  2 ) comprises a pair of rollers, one made of rubber ( 4 A- 4 B) and the other of engraved steel ( 5 A- 5 B), the latter being pulled by the corresponding continuous inner and outer strip of paper (P 1  or P 2 ) passing between each pair and guided by casters ( 6 ,  7 ,  8  and  9 ); said joining station ( 3 ) is placed after the two engraving stations ( 1 - 2 ), and it also comprises two rollers, a wheel roller ( 10 ) and a pulled counter-wheel roller ( 11 ), between which the continuous strips of paper (P 1  and P 2 ) are aligned, so that they can be joined by their edges and, thus, said wheel roller ( 10 ) presents, along its length, various rings ( 12 ) mounted on O-rings ( 13 ), each ring constituting the protruding means for supplementary pressure and the realization of the fastening bands by mechanical lamination (F); it is characterized in that the stations ( 1 ,  2  and  3 ) are arranged in a cooperative sequence so that the lateral joining bands (F) can be applied against the lower strip of paper (P 1 ), thus on the lower or inner side of the finished continuous paper (P 3 ) which, in turn, is rolled or folded to emboss (lower side) the lateral joining bands (F). 
     
     
         2 . The edge embosser for converting paper tissue, according to  claim 1 , wherein one or more joining bands (F) can be optionally produced by mechanic lamination at any points of the width of the finished continuous paper width (P 3 ).
