Abstract
An instrument for determining the spreading capacity of a coating or a surface, including a plate on which a gripping system is secured, the tool including a measuring system configured to measure the coating to be spread, wherein the measuring system includes at least one force sensor for generating data relating to the average force applied on the instrument, the maximum force applied on the instrument and the duration, in order to provide a signal representative of the capacity of the coating to be spread or the surface to be spread.
Claims21
An instrument for determining a spreading capacity of a coating or a surface comprising:
- a plate for spreading the coating,
- a grip connected to the plate,
- a measuring system configured to measure the coating to be spread, wherein said measuring system comprises at least one force sensor for sensing a force during a spreading gesture that spreads the coating and a controller coupled to the force sensor and arranged for generating data relating to an average force sensed during each spreading gesture, a maximum force sensed during each spreading gesture, and a duration of each spreading gesture,
- wherein said controller is further arranged to process said data and provide a signal representative of the spreading capacity of the coating to be spread or of the surface to be coated based on said average force, said maximum force, and said duration of each spreading gesture.
A method for determining a spreading capacity of a coating or a surface comprising:
- providing a coating;
- providing an instrument for determining the spreading capacity of the coating or surface comprising:
- (a) a plate for spreading the coating, (b) a grip connected to the plate, said tool comprising a measuring system configured to measure the coating to spread including at least one force sensor for sensing a force during a spreading gesture that spreads the coating and a controller coupled to the force sensor;
- placing said coating on the surface to be coated;
- spreading said coating using said instrument;
- said controller of said measuring system generating data during said spreading relating to an average force sensed during each spreading gesture, a maximum force sensed during each spreading gesture, and a duration of each spreading gesture, and
- wherein said controller also processes said data and provides a signal representative of the spreading capacity of the coating to be spread or of the surface to be coated based on said average force, said maximum force, and said duration of each spreading gesture.
