Embodiment Construction
[0018] Figure 1 shows a winding device WV with a belt R guided by guide pulleys R1-R5. The belt forms a loop 2 between the guide pulleys R1, R2, in which the roll W of wound cloth is formed. The fabric 1 is guided between two guide rollers R1 and R2 and wound onto a bobbin H. As shown in FIG. The bobbin H is housed by a central disc (not shown) mounted transversely and fixedly and internally subjected to a subatmospheric pressure at least during the start of the winding process. Further details of this embodiment are described, for example, in EP-A1-799337.
[0019] As the diameter of the wound cloth roll W increases, so does the loop 2 . The belt R is under tension under the action of the rollers Z so that the wound cloth roll W is under pressure during winding by the belt R. The drum Z is controlled by a valve 4 which is controlled by means of a line 4 via a control device ST. Drive device 8 , which is activated via line 6 under the action of said control device ST, driv...
