Winder

Abstract

A winder has at least two winding assemblies, in which each winding assembly is arranged on its own carriage. This winder is an improvement over conventional winders, such as those used to wind copper pipes.

1 . A winder comprising at least two winding assemblies, each winding assembly being disposed on a separate carriage.  
     
     
         2 . The winder according to  claim 1 , wherein the carriages have separate drives.  
     
     
         3 . The winder according to  claim 1 , wherein the carriages are displaceable about different centers of rotation.  
     
     
         4 . A winder comprising at least two winding assemblies that are displaceable between a winding position and an auxiliary activity position, said two positions being arranged at an angle less than 180° relative to one another.  
     
     
         5 . The winder according to  claim 4 , wherein said two positions are arranged at an angle equal to or less than 90° relative to one another.  
     
     
         6 . A winder comprising at least one winding assembly that is displaceable and supported on a sliding bearing.  
     
     
         7 . The winder according to  claim 6 , wherein the sliding bearing has a sliding surface that is a flooring surface on which said at least one winding assembly is arranged.  
     
     
         8 . A winder comprising at least one displaceable winding assembly arranged on a carriage that is supported on a floor or base plate by an air cushion, said air cushion being adapted to be switched on and off.  
     
     
         9 . A winder comprising at least one displaceable winding assembly arranged on a carriage, said carriage having apertures in an underside thereof, through which fluid media can be passed.  
     
     
         10 . A winder comprising at least one displaceable winding assembly arranged on a carriage, said carriage having apertures in an underside thereof, in which an underpressure is created.  
     
     
         11 . A winder comprising a winding element for winding a workpiece, said winding element comprising: 
 at least one winding cylinder;    at least one winding flange;    at least one workpiece securing mechanism, and    a workpiece guide that is provided radially inside an outer radius of the winding flange.    
     
     
         12 . The winder according to  claim 11 , wherein the workpiece guide is removable from the winding flange.  
     
     
         13 . The winder according to  claim 11 , wherein the workpiece guide is guided on the winding flange.  
     
     
         14 . The winder according to  claim 11 , wherein the workpiece guide is displaceable into and out of the winding flange.
