Filling removing method for tube, involves allowing fluid flow under pressure in tube with movement by pressure pin, where fluid flow is pressurized through slit that is arranged between circumference of pin and entrance opening

摘要

The method involves allowing fluid flow under pressure in a tube with a movement by a pressure pin (3), where the fluid flow is pressurized through a slit that is arranged between circumference of the pressure pin and an entrance opening (9). The flow is directed to an interface (8) between inside of a sleeve and an outer circumference of filling (1), where a surface of an entrance opening is equal to or smaller than a surface (16) of the filling. An independent claim is also included for a device for removing filling from a tube.
