Device for winding and unwinding two-dimensional roll material

Abstract

The invention refers to a device for winding or unwinding two-dimensional roll material, such as for example sheets and/or bands of artificial turf, with at least one pair of tongs, wherein at least two gripping and/or tongs elements delimiting at least partly a winding space with each time at least one roller arranged at the ends of the gripping and/or tongs elements and having a roller surface are arranged, wherein at least one of the rollers can be driven rotationally, and the rollers can be put into contact with a winding of the two-dimensional roll material in order to set the two-dimensional roll material in a winding motion that is in opposite direction of the rotational movement of the rollers for winding or unwinding.

What is claimed is: 
     
         1 . Devices for winding or unwinding of two-dimensional sheet material, comprising:
 at least one pair of tongs, wherein at least two gripping and/or tongs elements delimiting at least partly a winding space interact with at least one roller each being arranged at the ends of the gripping and/or tongs elements and having a roller surface, wherein at least one of the rollers can be driven rotatorily, and the rollers are arranged to be put against a winding of the two-dimensional roll material in order to set the winding in a winding motion in opposite direction of the turning movement of the rollers for winding or unwinding the two dimensional roll material.   
     
     
         2 . Device according to  claim 1 , further comprising two rollers extending parallel to each other. 
     
     
         3 . Device according to  claim 1 , wherein at least one roller is forced-driven. 
     
     
         4 . Device according to  claim 1 , wherein the at least one roller has an electric or hydraulic drive. 
     
     
         5 . Device according to  claim 1 , further comprising two pairs of tongs orientated parallel with respect to each other. 
     
     
         6 . Device according to  claim 1 , wherein the at least one roller is supported on at least one pair of tongs. 
     
     
         7 . Device according to  claim 1 , wherein the at least one pair of tongs is arranged for performing a gripping movement. 
     
     
         8 . Device according to  claim 1 , further comprising two parallel orientated pairs of tongs, and wherein the tongs in each of the pairs respectively have stationary and movable gripping and/or tongs elements. 
     
     
         9 . Device according to  claim 1 , further comprising two parallel orientated pairs of tongs, and wherein the tongs each have stationary and movable gripping and/or tongs elements, and wherein the gripping and/or tongs elements of each of the pairs of tongs are moved hydraulically relatively towards each other. 
     
     
         10 . Device according to  claim 1 , further comprising two parallel orientated pairs of tongs, and wherein each of the pairs of tongs has stationary and movable gripping and/or tongs elements, and wherein at the stationary gripping and/or tongs element in each of the pairs, respectively, a gripping element axle is provided by which the gripping movement is performed as swiveling movement. 
     
     
         11 . Device according to  claim 1 , further comprising two parallel orientated pairs of tongs, and wherein each of the pairs of tongs has stationary and movable gripping and/or tongs elements, and wherein at the movable gripping and/or tongs elements at least one reinforcement or two reinforcements are provided. 
     
     
         12 . Device according to  claim 1 , further comprising two parallel orientated tongs, and wherein each of the pairs of tongs has stationary and movable gripping and/or tongs elements, and wherein the roller arranged at the movable gripping and/or tongs elements is supported swiveling on a roller swivel axle, or the roller is attached exchangeably to the roller swivel axle. 
     
     
         13 . Device according to  claim 1 , further comprising a transport bracket for transporting the device. 
     
     
         14 . Device according to  claim 13 , wherein the transport bracket is joined to stationary gripping and/or tongs elements of the at least one pair of tongs. 
     
     
         15 . Device according to  claim 13 , wherein the transport bracket is arranged to be shortened for lifting the winding of the two-dimensional roll material. 
     
     
         16 . Device according to  claim 13 , further comprising an electro-mechanic drive for the transport bracket. 
     
     
         17 . Device according to  claim 1 , further comprising a cutting or sawing device for cutting two-dimensional roll material. 
     
     
         18 . Device according to  claim 17 , further comprising two parallel orientated pairs of tongs, and wherein each of the pairs of tongs has stationary and movable gripping and/or tongs elements, and wherein the cutting or sawing device is provided at a stationary gripping or tongs element of the at least one of the pairs of tongs. 
     
     
         19 . Device according to  claim 17 , wherein the sawing device is configured as a circular saw driven by an electro-motor. 
     
     
         20 . Device according to  claim 1 , that is configured as a coupling device to an automotive vehicle or as an automotive vehicle.
