Winder

Abstract

Winder with a contacting roller ( 10 ), which can be placed against the periphery of a reel ( 14 ), characterized in that the contacting roller ( 10 ) is divided at least in two roller segments ( 46; 34 ), of which at least one ( 34 ) has an engaging mechanism ( 38, 40 ), with which it can be engaged and disengaged independently of a different roller segment ( 46 ).

1 . Winder with a contacting roller ( 10 ), which can be placed against the periphery of a reel ( 14 ), characterized in that the contacting roller ( 10 ) is divided at least in two roller segments ( 46 ;  34 ), of which at least one ( 34 ) has an engaging mechanism ( 38 ,  40 ), with which it can be engaged and disengaged independently of a different roller segment ( 46 ).  
     
     
         2 . The winder of  claim 1 , characterized in that the contacting roller ( 10 ) can be shifted axially relatively to the reel ( 14 ).  
     
     
         3 . The winder of claims  1  or  2 , characterized by at least one slice-cutting knife ( 62 ), which is divided into at least two knife segments ( 94 ;  95 ), of which at least one can be displaced independently of the other.  
     
     
         4 . The winder of claims  2  and  3 , characterized in that the divided slice-cutting knife ( 62 ) can be shifted axially relatively to the reel ( 14 ) jointly with the divided contacting roller ( 10 ).  
     
     
         5 . The winder of one of the claims  3  or  4 , characterized in that the slice-cutting knife ( 62 ) and the contacting roller ( 10 ) are divided at the same axial position.  
     
     
         6 . The winder of one of the preceding claims, characterized in 
 that a main roller segment ( 46 ) and at least one subsidiary roller segment ( 34 ) of the contacting roller ( 10 ), having a contacting mechanism ( 38 ,  40 ) are disposed at an oscillating link ( 26 ),    that each subsidiary roller segment ( 34 ) can be shifted with its contacting mechanism ( 38 ,  40 ) independently of the other roller segments ( 34 ;  46 ) into a first and a second position, for which the subsidiary roller segment ( 34 ), in the first position, is aligned axially with the main roller segment ( 46 ) and, in the second position, is removed further than the main roller segment ( 46 ) from the reel ( 14 ) and    that, depending on the positions of the contacting mechanisms ( 38 ,  40 ) of the subsidiary roller segments ( 34 ), the main roller segment ( 46 ) or the main roller segment ( 46 ) and at least one of the subsidiary roller segments ( 34 ) can be placed suddenly against the reel ( 14 ) or a core ( 13 ) of a reel ( 14 ).    
     
     
         7 . The winder of  claim 6 , characterized in that the main roller segment ( 46 ) or the main roller segment ( 46 ) and at least one of the subsidiary roller segments ( 34 ) can be placed suddenly, through pivoting of the oscillating link ( 26 ) by means of a pneumatic cylinder ( 52 ), against the reel ( 14 ) or a core ( 13 ) of a reel ( 14 ).  
     
     
         8 . The winder of  claim 7  and one of the  claims 3  to  5 , characterized in that the at least one divided slice-cutting knife ( 62 ) is disposed in such a manner with respect to the contacting roller ( 10 ), so that a sheet ( 12 ), which is passed between the contacting roller ( 10 ) and a core ( 72 ) of the second reel ( 75 ) and wound on a first reel ( 14 ) and, by the sudden placement of at least one main roller segment ( 46 ) against the core ( 72 ) of the second reel ( 75 ), is clamped between the engaged roller segments ( 46 ;  34 ) and the core ( 72 ), can be severed by a simultaneous displacement of the appropriate knife segments ( 94 ,  95 ) at a place between the core ( 72 ) of the second reel ( 75 ) and the first reel ( 14 ).  
     
     
         9 . The winder of  claim 8 , characterized in that, if the axes of the core ( 72 ) of the second reel ( 75 ) and of the divided contacting roller ( 10 ) are disposed in an essentially horizontal plane, the sheet ( 12 ) can be supplied by means of suitably disposed turn-around rollers ( 58 ,  60 ) from above as well as from below the gap between the divided contacting roller ( 10 ) and the core ( 72 ) of the second reel ( 75 ) and a divided slice-cutting knife ( 62 ) is disposed above as well as below the divided contacting roller ( 10 )  
     
     
         10 . The winder of  claim 2  and one of the  claims 6  to  9 , characterized in that the oscillating link ( 26 ) with the roller segments ( 46 ;  34 ) and, if present, the knife segments ( 94 ;  95 ) can be adjusted jointly and axially relative to the reel ( 14 ;  72 ) by a distance of at least half of the axial extend of a subsidiary roller segment ( 34 ).
