Abstract

Apparatus for continually joining paper webs, comprising means able to compress the said webs ( 5, 6 ) onto an impression cylinder or roller ( 4 ) while the webs advance toward an outlet section of the apparatus, characterized in that said compressive means include a roller or cylinder ( 2 ) which exhibits a hard outer surface ( 20 ) supported by an underlying elastic surface ( 23 ).

Claims

exact text as granted — not AI-modified
1 . Apparatus for continually joining paper webs, comprising means able to compress the said webs onto an impression cylinder or roller while the webs advance toward an outlet section of the apparatus, characterized in that the said compressive means include a roller or cylinder which exhibits a hard outer surface supported by an underlying elastic surface.  
   
   
       2 . Apparatus according to  claim 1 , characterized in that the said elastic surface is in turn supported by a rigid surface.  
   
   
       3 . Apparatus according to  claim 1 , characterized in that the said outer surface of said compression roller is made up of a helicoidal body having preset pitch and direction and being applied on said elastic surface.  
   
   
       4 . Apparatus according to  claim 1 , characterized in that the said outer surface sheathes completely the said elastic surface.  
   
   
       5 . Apparatus according to  claim 1 , characterized in that the outer surface of said compression roller is made of steel.  
   
   
       6 . Apparatus according to  claim 1 , characterized in that the elastic surface of said compression roller is made of rubber.  
   
   
       7 . Apparatus according to  claim 1 , characterized in that the said impression cylinder is provided with surface reliefs and/or depressions.  
   
   
       8 . Apparatus according to  claim 1 , characterized in that the said impression cylinder is an embossing cylinder.  
   
   
       9 . Method for carrying out the union of two paper webs by a mutual compression of the concerned webs, characterized in that it includes compressing the said webs between a pressure roller or cylinder, provided with a hard outer surface and an underlying elastic surface, and an impression roller or cylinder provided with surface reliefs and/or depressions.  
   
   
       10 . Method according to  claim 9  characterized in that the said impression cylinder is an embossing cylinder.
