Abstract
A method and device for emptying a belt reel or bobbin filled with tobacco leaves or portions thereof, the belt being withdrawn from the bobbin and wound on a reel, while each time the tobacco leaf portions are removed from the corresponding strip of belt, wherein prior to the removal of each tobacco leaf portion the belt is stretched in excess of the normal tensile force required for winding off the belt in order to detach the tobacco leaf portion from the belt, which additional stretching effect need only be very slight in order to pick up all tobacco leaf portions without disturbance.
Claims10
Apparatus for emptying a reel or bobbin which is in the form of a belt wound upon itself and having discrete portions of tobacco sandwiched between the successive layers of the bobbin, which comprises:
- support means for supporting the bobbin during unwinding of the belt therefrom;
- unwinding means for unwinding the belt from the bobbin, said unwinding means being spaced from said support means whereby a length of belt is disposed therebetween and upon one surface of which discrete portions of tobacco are exposed;
- brake means for causing said length of belt to be tensioned under the action of said unwinding means;
- removal means disposed adjacent said one surface of the length of belt for successively removing the discrete portions of tobacco therefrom;
- and
- means for altering the tension of said length of belt when a discrete portion of tobacco is registered with said removal means, the tension of the belt being altered sufficiently to assure loosening of the tobacco from said one surface.
