Abstract
The device for coating an element by means of a swab impregnated with a coating composition comprises: a mobile carriage bearing the swab, said carriage being movable along a guiding path; a means for pushing the swab towards the element to be coated so that a quantity of the composition released from the swab coats the element, and a means for distributing the composition, so that the coating is substantially uniform.
Claims65
Device for coating at least a part of an element by means of a swab, said device comprising:
- a support provided with a guiding path and with a means for bearing the element to be coated;
- a mobile carriage with means for bearing the swab, said carriage being movable along the guiding path;
- a means for ensuring a movement of the mobile carriage along the guiding path with respect to the element to be coated, whereby ensuring a relative movement of the swab with respect to the element to be coated,
- a means for conducting a coating composition on the support to be coated, said means having an open end adjacent to the swab, and
- a means for pushing the swab towards the element to be coated so that the swab acts as means for distributing the coating composition flowing out of the open end, whereby the open end of the means for conducting a coating composition is mounted on a carrier movable along a guiding path with respect to the element to be coated, said open end being located with respect to the swab, so that the composition flowing out from the open end contacts first the element to be coated before being distributed by the swab, and
- whereby the means for conducting the coating composition comprises a volumetric pump adapted for conducting to the open end the requested amount of coating composition so that after distribution of the coating composition on the element by the swab, a substantially uniform coating coats the element.
Device for coating at least a part of an element by means of a swab, said device comprising:
- a support provided with a guiding path and with a means for bearing the element to be coated;
- a mobile carriage with means for bearing the swab, said carriage being movable along the guiding path;
- a means for ensuring a movement of the mobile carriage along the guiding path with respect to the element to be coated, whereby ensuring a relative movement of the swab with respect to the element to be coated,
- a means for conducting coating composition comprising at least a flexible pipe with a inner diameter of less than 2 mm extending from a first open end to a second open end, whereby the second open end of the flexible pipe is mounted on a carrier movable along a guiding path with respect to the element to be coated, the second end being located with respect to the swab, so that the composition flowing out from the open end contacts first the element to be coated before being distributed by the swab, and
- a means for pushing the swab towards the element to be coated so that the swab acts as means for distributing the coating composition flowing out of the open end, whereby the means for conducting the coating composition comprises:
- a container for the coating composition, whereby said container is provided with a mixing means and with a guiding path for positioning at least the first open end of the flexible pipe,
- a peristaltic pump acting on a portion of the flexible pipe, said pump being adapted for conducting from the first open end of the flexible pipe to the second open end of the pipe the requested amount of coating composition so that after distribution of the coating composition on the element by the swab, a substantially uniform coating coats the element.
Device for coating at least a part of an element by means of a swab, in which a coating composition contacts the support to be coated, said device comprising:
- a support provided with a guiding path and with a means for bearing the element to be coated;
- a mobile carriage with means for bearing the swab, said carriage being movable along the guiding path;
- a means for ensuring a movement of the mobile carriage along the guiding path with respect to the element to be coated, whereby ensuring a relative movement of the swab with respect to the element to be coated,
- a protection element movable with respect to the support between a position enabling the coating of the element to be coated and a position protecting at least a first portion of the element after its coating.
A process for coating an element with a coating composition, in which a volumetric pump is used for controlling the flow of a coating composition in a flexible pipe having an open end adjacent to a swab, in which the swab and the open end of the flexible tube are in relative movement with respect to the element to be coated, and in which the swab is contacting the element to be coated for distributing the coating composition flowing from the open end on the element to be coated,
- whereby the volumetric pump is controlled for conducting to the open end the requested amount of coating composition so that after distribution of the coating composition on the element by the swab, a substantially uniform coating coats the element.
