Abstract
A method is provided for fitting an elastic hose onto a dimensionally stable connector, wherein the method involves the following steps: a) generating a flow of pressurized gas out of the connector; b) bringing the hose end to the connector against the flow direction of the gas out of the connector; and c) reducing the flow cross section of the hose beyond the connection point in order to generate dynamic pressure in the hose, widening the hose end; d) fitting the hose end onto the connector; and e) increasing the flow cross section of the hose beyond the connection point to mount the hose end to the outside of the connector.
Claims11
A method for attaching an elastic hose onto a dimensionally stable spout, wherein the method comprises the following steps:
- a) generating a flow of pressurized gas from the spout;
- b) placing an end of the elastic hose in an elastic and deformable hose mount of a hose assembly tool;
- c) guiding the end of the hose toward the spout against a direction of the flow of the gas from the spout;
- d) reducing a flow cross-section of the hose after a connection point for generating a dynamic pressure in the hose that expands the hose end with the hose assembly tool by which the hose can be cut off or whose flow can be restricted, and wherein the elastic and deformable hose mount deforms to allow a diameter increase of the hose end;
- e) attaching the hose end to the spout;
- and
- f) increasing the flow cross-section of the hose after the connection point for applying the hose end to an outer side of the spout where the hose is held at and is attached to the spout by the hose assembly tool and such that the reduction of the flow cross-section in accordance with step d) and the increase of the flow cross-section in accordance with step f) are carried out by the hose assembly tool whereat the increase of the flow cross-section in accordance with step f) happens through releasing of the hose out of the hose assembly tool.
