A method of pretreating suspended flexible containers of the type including an upper tubular part of a flexible material and a lower bottom rigid part. The method comprises applying to a lower edge portion of the upper tubular part a pulling force in a longitudinal direction towards the lower bottom part so that the upper tubular part elongates to its maximum length, and subsequent fixedly connecting the lower edge of the upper tubular part to the lower bottom part. An arrangement for pretreating such containers comprises means for suspending the container by an upper edge portion of the tubular part, pulling means for pulling the lower edge of the upper tubular parts in a longitudinal direction to the lower bottom part and for subsequently fixedly connecting the lower edge of the upper tubular part to the lower bottom part, means for connecting the pulling means to the upper tubular part, and means for connecting the pulling means to the lower bottom parts. |
