Abstract: A system of connecting two flexible tubes together using the rolled back ends of the tubs to create abutment surfaces which when urged together for a fluid-tight seal. The rolled back ends are supported on tube supports including a spigot extending along the outside of the tube and over which the rolled ends are supported. Urging two rolled backed ends together creates a fluid tight seal. This may be achieved by attaching flanges to the rolled back ends and using standing clamping means. Alternatively, other types of clamping means can be used.

Abstract: A system of connecting two flexible tubes together using rolled back ends of the tubes to create abutment surfaces which when urged together form a fluid-tight seal. The rolled back ends are supported on tube supports including a spigot extending along the outside of the tube and over which the rolled ends are supported. Urging two rolled backed ends together creates a fluid tight seal. In one example, this urging may be achieved by attaching flanges to the rolled back ends and using standard clamping methods. Alternatively, other types of clamping methods can be used.

Abstract: Apparatus for rolling back the end of a flexible tube, the apparatus comprising a flexible tube support, a plunger assembly having a flared conical end, a cover around the outside of the plunger assembly and actuator means for moving the plunger assembly into the flexible tube, and moving the cover over the rolled back end. In use a flexible tube is placed into the tube support, and its end is placed over the conical end. While the tube is held in position, plunger assembly advanced into the tube, flaring the end of the tube. The cover then continues to advance urging the flared end back on forming the rolled back end. The apparatus can fit a sleeve over the rolled back end, holding it is place, and can connect the sleeve to a tubing support.
