The present invention relates to a method where rolling a length of compressed flexible material (4) into a roll (43) use a flexible roll-up belt (101, 102) moving along a belt pathway, said pathway defined by a number of rollers (5, 19), wherein at least one of said rollers (5) is active where its rotation is driven by a drive motor and drives the belt along said belt pathway, the roll-up belt can be tightened or loosened along said belt pathway by changing the position of at least one moveable roller (17) and thereby changing the length of the pathway, wherein said method comprises feeding said compressed flexible material (4) into a meeting loop cavity (14) shaped by a segment of said roll-up belt (101, 102) along said roll-up belt pathway, whereby material follows the inner surface of the loop and the rolling of the flexible material is initiated, gradually increasing the length of the segment of said roll-up belt in said meeting loop cavity (14) to ensure that that the roll-up belt segment in said meeting loop cavity gradually and continuously follows the increasing size of the roll (43) and supports the outer contour of the roll, wherein said gradual increase of the segment comprises the steps of gradually loosening the roll-up belt (101, 102) by changing the position of said at least one moveable roller (17) and simultaneously controlling the rotation speed of said at least one active roller (5) to control the length of said belt segment in said meeting loop cavity. Thereby, an automatic rolling of flexible material (4) is obtained, which adaptably expands a meeting loop cavity (14) to ensure that the rolling is initiated in a controlled manner, and furthermore, that one apparatus (1) performing the method according to the present invention may be used to roll flexible material of various dimensions and characteristics. |
