Manual unrolling device

Abstract

A manual unrolling device for unrolling and tearing off a rolled up foil or paper web includes (a) a housing in which a winding body can be placed and having at least one web outlet opening; (b) at least one lid cover connected to the housing via a hinge; and at least one cutting element for separating a web section. The cutting element is arranged on a lower side of the lid cover that is directed toward the web outlet opening. A redirecting bar, and at least two pull-off bars across which the web is guided, are arranged parallel to each other at the web outlet opening. Upper edges of at least one pull-off bar are provided with a friction-enhancing coating, and the pull-off bars have a gap between them into which the cutting element dips when the lid cover is closed.

       4 . A manual unrolling device as defined in  claim 2 , wherein an edge of a pull-off bar that is directed toward an outer side of the housing exhibits at least one discontinuity. 
   
   
       5 . A manual unrolling device as defined in  claim 1 , wherein said hinge is a film hinge. 
   
   
       6 . A manual unrolling device as defined in  claim 2 , wherein said hinge is a film hinge. 
   
   
       7 . A manual unrolling device as defined in  claim 1 , wherein the housing includes at least one hinged side flap having at least one holding mandrel for insertion into a hollow cylindrical winding body of the web. 
   
   
       8 . A manual unrolling device as defined in  claim 2 , wherein the housing includes at least one hinged side flap having at least one holding mandrel for insertion into a hollow cylindrical winding body of the web. 
   
   
       9 . A manual unrolling device as defined in  claim 7 , wherein the housing has a one slot-shaped recess into which the holding mandrel, formed as a flat bar, can be inserted. 
   
   
       10 . A manual unrolling device as defined in  claim 8 , wherein the housing has a one slot-shaped recess into which the holding mandrel, formed as a flat bar, can be inserted. 
   
   
       11 . A manual unrolling device as defined in  claim 1 , further comprising at least one spring element which is deflected when the lid cover is closed. 
   
   
       12 . A manual unrolling device as defined in  claim 2 , further comprising at least one spring element which is deflected when the lid cover is closed. 
   
   
       13 . A manual unrolling device as defined in  claim 11 , wherein the spring element is a leaf spring. 
   
   
       14 . A manual unrolling device as defined in  claim 12 , wherein the spring element is a leaf spring. 
   
   
       15 . A manual unrolling device as defined in  claim 11 , wherein the spring element is arranged centrally in the area of the redirecting and pull-off bars and wherein the spring element presses from below against the web that is guided above it. 
   
   
       16 . A manual unrolling device as defined in  claim 12 , wherein the spring element is arranged centrally in the area of the redirecting and pull-off bars and wherein the spring element presses from below against the web that is guided above it. 
   
   
       17 . A manual unrolling device as defined in  claim 11 , wherein said spring elements are arranged in the housing on both sides in the frontal area. 
   
   
       18 . A manual unrolling device as defined in  claim 12 , wherein said spring elements are arranged in the housing on both sides in the frontal area. 
   
   
       19 . A manual unrolling device as defined in  claim 1 , further comprising a second redirecting bar arranged on the inside of the housing ahead of the first pull-off bar.
