Abstract

An apparatus for applying a viscous material, comprising a bell having a circumferential mounting rim, and a feed line, wherein the material is conveyable via a conveying element through the feed line into the bell, wherein the bell can be transported with the mounting rim, in a direction of mounting, over a protruding element, in particular a rivet head, of a component, in order to encase the element with the material, wherein in the region of the bell or the feed line a metering member is provided, wherein in the course of an application process a flow of the material can be influenced by the metering member.

First claim

The invention claimed is:

1. An apparatus for applying a viscous material, comprising:
a bell having a circumferential mounting rim; and
a feed line,

wherein the material is conveyable via a conveying means through the feed line into the bell,
wherein the bell can be transported with the mounting rim, in a direction of mounting, over a protruding element of a component, in order to encase the element with the material,
wherein a metering member is provided in, on, or adjacent to the bell or the feed line, wherein the metering member is configured to influence a flow of the material during an application process, and
wherein the bell can be lifted away from the element and the metering member is configured to retract the material after the bell is lifted away from the element.

2. The apparatus as claimed in claim 1 , wherein the metering member is arranged on a branch of the feed line.

3. The apparatus as claimed in claim 1 , wherein the metering member comprises a movable metering piston.

4. The apparatus as claimed in claim 3 , wherein the metering piston is movable in such a way that it can be driven by an actuator.

5. The apparatus as claimed in claim 3 , wherein the metering piston, in at least one position, terminates substantially flush with a wall of the feed line and/or of the bell.

6. The apparatus as claimed in claim 3 , wherein the metering piston is movable in such a way that it can be driven by an actuator in two directions.

7. The apparatus as claimed in claim 1 , wherein, after the bell has been lifted off the element, a retraction of the material is realized by the metering member.

8. A method for applying a viscous material to a protruding element of a component by the apparatus as claimed in claim 1 , comprising:
filling of the bell with the viscous material, so that the element is encased, wherein, at least in part, advancement of the viscous material is realized by the metering member; and removing the bell from the element.

9. The method as claimed in claim 8 , further comprising:
retraction of the material by the metering member in the course of removal of the bell from the element, in order to facilitate a separation of a thread of the viscous material.

10. The apparatus of claim 1 , wherein the protruding element of a component comprises a rivet head.

11. The apparatus as claimed in claim 1 , wherein the metering member is arranged on a branch of the feed line just before an entry of the feed line into the bell.
