Abstract

Abstract The apparatus comprises a tank for retaining a pool of supporting liquid, a dispensing device associated with the tank for placing pigmented material on the surface of the pool, a roller for conveying a substrate to be coated into surface contact with the pool to lift the pigmented material from the pool, and selectively operable manipulating devices arranged to provide a desired pattern on the pigmented material of the pool. Manipulating devices comprise wave-generators, undulating tank side walls, and devices for accelerating and decelerating the substrate, each providing a characteristic visual effect in the finished product.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 60 words
Apparatus in accordance with claim 1 wherein said movable side wall member is flexible, and said side wall member moving means being a motor means connected to said movable side wall member for moving a portion of the side wall member in a transverse direction to change the width of the flow path for the support liquid in the tank.
Claim 2
Dependent Claim 46 words
Apparatus in accordance with claim 2 including a tape movable along said side wall member in a position for contact with the support liquid, and means connected to the tape for moving the tape at a speed approximating the speed of movement of the support liquid.
Claim 3
Dependent Claim 39 words
Apparatus in accordance with claim 1, and a movable wall member associated with each sidewall of said tank, said means coupled to each of said movable wall members causing said movable wall members to move inwardly toward each other.
Claim 4
Dependent Claim 57 words
Apparatus in accordance with claim 4, and flexible web means coupled to said movable wall members and movable with respect thereto in a direction generally parallel to the direction of flow of the support liquid in said tank, and means coupled to said web means for moving said web means with respect to said movable wall members.
Claim 5
Dependent Claim 44 words
Apparatus in accordance with claim 5, wherein said apparatus includes variable speed drive means coupled to said pick-up roll so that variations in the rotative speed of said pick-up roll produce variations in the color density of the coating material transferred to the substrate.
Claim 6
Dependent Claim 42 words
Apparatus in accordance with claim 1, wherein said apparatus for generating a wave pattern in said tank comprises a crankshaft disposed above said tank, and at least one agitator plate normally disposed in said support liquid and pivotably coupled to said crankshaft.
Claim 7
Dependent Claim 44 words
Apparatus in accordance with claim 1, wherein said apparatus includes variable speed drive means coupled to said pick-up roll so that variations in the rotative speed of said pick-up roll produce variations in the color density of the coating material transferred to the substrate.
Claim 8
Dependent Claim 139 words
In apparatus comprising a tank for retaining a support liquid, means associated with the tank for maintaining the support liquid in flowing condition in the tank, means associated with the tank for placing a quantity of pigmented coating material on the surface of the support liquid, and means associated with the tank for transferring the coating material from the support liquid to a substrate, means associated with the tank for manipulating the coating material on the support liquid to produce a desired decorative effect, said manipulating means comprising at least one movable side wall member disposed in said tank and having means coupled thereto for selectively moving said wall member laterally inwardly with respect to the sides of said tank in a direction generally transverse with respect to the direction of flow of the support liquid in the tank.
Claim 9
Dependent Claim 56 words
In apparatus in accordance with claim 9, a movable wall member associated with each side wall of said tank and having means coupled thereto for selectively moving it laterally inwardly with respect to a side of said tank, said means coupled to said movable wall members causing said wall members to move inwardly toward each other.
Claim 10
Dependent Claim 50 words
In apparatus in accordance with claim 10, flexible web means coupled to said movable wall members and movable with respect thereto in a direction generally parallel to the direction of flow of the support liquid in said tank, and means coupled to said web means for moving said web means.
