Abstract
Method for the forming of a fluid-tight separating closure of a conduit (1) involving the following steps: providing of a conduit (1) with a sleeve (2), positioning of the conduit (1) with the sleeve (2) between a die (3) and a stamp (4), compressing of the sleeve (2) by a relative movement between the die (3) and the stamp (4) in order to form a closure (5); severing of the closure (5) in a compressed region (6) by a severing tool (7) such that a contact line (8) between the severing tool (7) and the sleeve (2) during severing is shorter than an obtained severing edge (9) of the sleeve (2).
Claims6
A method for the forming of a fluid-tight separating closure of a conduit, the method comprising:
- positioning a conduit with a sleeve of the conduit between a die and a stamp of a device;
- compressing the sleeve by a relative movement between the die and the stamp in order to form a closure in the sleeve;
- severing the closure in a compressed region by a severing tool of the device, the stamp and the severing tool moveable relative to the die independent of one another, the severing tool having a blade including a blade edge length defined as a length of a blade edge of the blade that contacts the sleeve during the entire severing, a contact line along the blade edge between the severing tool and the sleeve during severing is shorter than the blade edge length;
- and
- removing the conduit from the device with the sleeve maintaining the closure in the sleeve by retracting the stamp and the severing tool of the device.
