Method and device for separating a roll of toilet paper

Abstract

A method and a device are provided for separating a roll of toilet paper which has plural tear lines. This invention is aimed to feed the continuous toilet paper into the device, which has a feeding element and a pulling element both provided for driving the paper. The pulling element can drive the toilet paper at a speed quicker than that of the feeding element, so that the toilet paper is pulled apart along the tear lines.

What is claimed is:  
     
         1 . A method for separating a roll of toilet paper into sections, said toilet paper having plural tear lines extended through a width thereof, said method comprising the step of: 
 feeding said toilet paper into a device having a feeding element and a pulling element both provided for driving said toilet paper; and    wherein said pulling element may drive said toilet paper at a speed quicker than that of said feeding element, so that said toilet paper may be pulled apart along said tear lines.    
     
     
         2 . A device for separating a roll of toilet paper into sections, said toilet paper having plural tear lines extended through a width thereof, said device comprising: 
 a feeding element having a first roller;    a pulling element having a second roller; and    wherein said second roller may have a tangential velocity quicker than that of said first roller so that said toilet paper is pulled apart along said tear lines into separated sections when being frictionally driven by said first and second rollers.    
     
     
         3 . The device as claimed in  claim 2 , wherein said feeding element and said pulling element have respective driving units to rotate said rollers.  
     
     
         4 . The device as claimed in  claim 3  further including a detector for sending out a signal to cause said first roller of said feeding element to stop rotation.  
     
     
         5 . The device as claimed in  claim 2  further including a single driving unit to selectively rotate said rollers.  
     
     
         6 . The device as claimed in  claim 5  further including a detector for sending out a signal to cause said driving unit to rotate both of said rollers and another signal to cause said driving unit to rotate only said second roller.  
     
     
         7 . The device as claimed in  claim 2 , wherein said feeding element further includes a press member for pressing said toilet paper onto said first roller.  
     
     
         8 . The device as claimed in  claim 7 , wherein said press member is biased towards said first roller by an elastic member.  
     
     
         9 . The device as claimed in  claim 7 , wherein said press member is configured into a roller.  
     
     
         10 . The device as claimed in  claim 2 , wherein said pulling element further includes a press member for pressing said toilet paper onto said second roller.  
     
     
         11 . The device as claimed in  claim 10 , wherein said press member is biased towards said second roller by an elastic member.  
     
     
         12 . The device as claimed in  claim 10 , wherein said press member is configured into a roller.  
     
     
         13 . The device as claimed in  claim 2 , wherein said feeding element and said pulling element have respective paper feeds to lead said toilet paper to said rollers.  
     
     
         14 . The device as claimed in  claim 2  further including a spray pipe used to wet said toilet paper.  
     
     
         15 . The device as claimed in  claim 2  further including a paper delivery used to lead out separated sections of said toilet paper.  
     
     
         16 . A device for separating toilet paper into sections, said toilet paper having tear lines extended through a width thereof, said device comprising: 
 a feeding element having a roller for frictionally driving said toilet paper;    a pulling element having a belt-type lap former and a board spaced from said lap formed by a certain spacing, said lap former and said board being provided for rolling up said toilet paper between said spacing; and    wherein said lap former may roll up said toilet paper at a speed quicker than the tangential velocity of said roller, so that said toilet paper is pulled apart along said tear lines into separated sections and is rolled into small rolls.    
     
     
         17 . The device as claimed in  claim 16  further including a detector for sending out a signal to cause said lap former to roll up said toilet paper at a speed quicker than the tangential velocity of said roller.  
     
     
         18 . The device as claimed in  claim 17 , wherein said detector may send out an additional signal to cause said roller of said feeding element to stop rotation.
