A method of separating from one another plastic bags included in a web, the bags being mutually defined by openings and perforations and being rolled up to a reel, comprises the steps that the outermost bag is withdrawn against the action of a pre-tensioning force, and that the edge of the opening located most proximal the end is brought into non-symmetrical engagement with a stop, whereafter the bag is released such that the web returns towards the reel under the action of the pre-tensioning force, the outermost bag being held captive and separated along the perforation. An apparatus for carrying out the method comprises a holder (11) with a vertical shaft (12) for the reel. A spring (13) is connected to the holder (11) and the reel. The holder is provided with a stop (14) spaced from the shaft (12) and placed asymmetrically in relation to the centre of the reel, the stop being provided with two shanks (15, 16) which form a space closed towards the reel. Furthermore, the holder (11) is provided with a braking spring (17) which is intended to abut against the periphery of the reel and damp the rotation of the reel. |
