A device is described for laying-out a convolute web of material, in particular a web of textile material, coming from a bale of cloth, said device comprising a frame structure which is adapted to be moved longitudinally along a stationary support structure and on which, via suspension means, the bale of cloth is supported such that it is caused to rotate about its winding shaft in response to the longitudinal movement of said frame structure. The drive means of the bale of cloth is constructed such that slippage between said drive means and said bale of cloth--which would prevent rotation of said bale of cloth--is avoided and that, with the aid of very simple structural means, a wide range of use of the device equipped with said drive means is achieved. For this purpose, the drive means comprises a tight rope, which, via guide rolls adapted to be displaced together with the frame structure, is guided over part of the surface of the bale of cloth in a position of frictional engagement.
A device for winding or unwinding a web of material with respect to a winding shaft, comprising an elongated stationary support structure, a frame movable longitudinally with respect to said support structure, suspension means on said frame for supporting said winding shaft and driving means, comprising at least two first guide rolls supported on said frame, being arranged on both sides of said winding shaft, rope means, having a first and a second end, said first end being fixed with respect to said movement of said frame, and said second end being connected to tensioning means for holding said rope means under tension, said rope means between said first and said second end contacting at least a part of said guide rolls and the web wound on said winding shaft, said rope means also being in frictional engagement with said wound web, said rope means further being adapted to being displaced in the direction of the circumference of said guide rolls and said web when said frame is moved relative to said support means in order to rotate said wound web on said winding shaft for winding or unwinding said web.
