Abstract:
Method of blow moulding a container from a hollow, elongated parison of a thermoplastic material, wherein the method comprises: —arranging the parison in a closed moulding equipment comprising a moulding cavity and at least one aperture, wherein the at least one aperture provides an opening into the moulding cavity from outside the closed moulding equipment, wherein the circumference of the at least one aperture is larger than or equal to a circumference of the parison, such that a first section of the parison is arranged inside the moulding cavity, a second section of the parison is arranged within the at least one aperture and a third section of the parison is arranged outside the closed moulding equipment, —closing a shutter system around the third section of the parison, thereby pinching the parison and providing a closed volume inside the first and second sections of the parison, —arranging a blow conduit in fluid communication with the closed volume inside the second section of the parison, —blowing pressurised gas from the blow conduit into the first and the second section of the parison, thereby forming first and second blow moulded sections, wherein the first blow moulded section is the container, and—separating the second blow moulded section from the first blow moulded section, thereby providing an opening in the container.
