An apparatus for applying a coating to an object includes a pair of reciprocating members which each include a porous resilient pad mounted for movement toward and away from each other. The apparatus includes a coating supply system for supplying coating to the resilient pads. The pads have a movement sequence from an initial rest position where the pads are spaced apart from one another to a coating loading position where the pads are in physical contact and have a degree of compression with each other to load the coating onto the pads, then the pads are moved to an intermediate rest position with the pads spaced apart an the object to be coated is moved between the pads. The sequence then includes a coating delivery position where the pads are in physical contact with each other and the object so that the pads have a degree of compression with each other and the object thereby applying the coating to the object.

Method for coating objects with a porous resilient matrix

Apparatus for coating of objects using a porous resilient matrix

An apparatus for applying a coating to an object includes a pair of rotating members each including a porous resilient roll mounted for counter-rotatory movement. The members are mounted so that they contact each other during a segment of the movement and are out of contact with each other at other segments of the movement. The apparatus includes a coating supply system for supplying a coating to the resilient rolls. The rotatory movement of the members includes a coating loading segment where the resilient rolls are in physical contact and have a degree of compression with the coating supply system for loading the coating into the rolls. The sequential movement also includes an intermediate segment where the resilient rolls are out of contact with each other and where an object to be coated is movable into position for movement between the resilient rolls when the rolls are in a coating delivery segment. In the coating delivery segment, the resilient rolls are in physical contact and have a degree of compression with each other and with the object to be coated as the object is moved between the rolls. The coating delivery segment serves to apply the coating to the object. A method for applying a coating to an object includes moving an object to be coated between rotating members, each of which includes a porous resilient roll mounted for counter rotatory motion to each other in a coating delivery segment of a sequential movement.
