A METHOD AND APPARATUS FOR MAKING ROLLS FROM FLEXIBLE MATERIAL, SUCH AS MINERAL WOOL

摘要

The present invention relates to a method and apparatus for making rolls (200) by rolling a length of compressed flexible material (201), such as compressed isolation wool, wherein said method comprises- tapering the end of said length of compressed flexible material (203) between a folding roller (101) comprising grip edges (103) and a roll-up belt (105) providing a support on one side of said length of compressed flexible material to maintain the compression of said compressed flexible material,- initiating the rolling of said length of compressed flexible material by rotating the folding roller in a direction whereby a tip (203) of the tapered end of said length of compressed flexible material is bent in the rolling direction (207) due to a gripping contact between the grip edges of said folding roller,- continued rolling of said length of said compressed flexible material (201) while supporting the roll by said roll-up belt (105) until a roll of a specific size has been obtained.;Thereby an automatic rolling of flexible material is obtained solving the above-mentioned problems by letting the folding roller (101) ensure that the initiation of the rolling is in a controlled manner.
