Abstract
Abstract An arrangement for marking articles or workpieces, particularly hot workpieces, such as coils of sheet metal with series of symbols which are individually applied in templates. The latter are in the form of symbols applied in a cylindrical portion and in a flange-like portion of a movable angle ring which is adjustable vertically and sideways. A spray nozzle is associated with each of the portions. The angle ring is connected to a trunnion fixed in an arm which is adjustable vertically and sideways by piston-cylinder units. One piston-cylinder unit is centered in a frame which is movable on a track by driven wheels, and the piston of this unit mounts a lifting table. Another piston-cylinder unit is connected to the aforementioned arm. One vertical spray nozzle is located above the flange-like portion of the angle ring on the outer end of the arm. A horizontal spray nozzle, furthermore, is located on the lower end of the trunnion, tiltable about a horizontal axis, inside the cylindrical portion of the angle ring. The spray nozzles are immersible by the piston-cylinder unit, in basins filled with paint solvents.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
An arrangement for marking articles or workpieces with paint or colored dust, particularly hot workpieces, such as coils of sheet metal, with series of symbols individually applied in templates, comprising: a single movable angle ring adjustable vertically and sideways and having templates in the form of symbols applied in a cylindrical portion and in a flange-like portion of said movable angle ring; said cylindrical portion being connected to said flange-like portion, a first spray nozzle being located on one side of said flange-like portion and a second spray nozzle being located in said cylindrical portion, said workpieces facing said flange-like portion and said cylindrical portion and being marked simultaneously in one operation on two surfaces by symbols of said templates.
Claim 2
Dependent Claim
120 words
An arrangement for marking articles or workpieces with paint or colored dust, particularly hot workpieces, such as coils of sheet metal, with series of symbols individually applied in templates, comprising: a single movable angle ring adjustable vertically and sideways and having templates in the form of symbols applied in a cylindrical portion and in a flange-like portion of said movable angle ring; said cylindrical portion being connected to said flange-like portion, a first spray nozzle being located on one side of said flange-like portion and a second spray nozzle being located in said cylindrical portion, said workpieces facing said flange-like portion and said cylindrical portion and being marked simultaneously in one operation on two surfaces by symbols of said templates.
Claim 3
Dependent Claim
131 words
An arrangement for marking articles or workpieces with paint or colored dust, particularly hot workpieces, such as coils of sheet metal, with series of symbols individually applied in templates, comprising: a movable angle ring adjustable vertically and sideways and having templates in the form of symbols applied in a cylindrical portion and in a flange-like portion of said movable angle ring; said cylindrical portion being connected to said flange-like portion; a first spray nozzle being located on one side of said flange-like portion and a second spray nozzle being located in said cylindrical portion, said workpieces facing said flange-like portion and said cylindrical portion; trunnion means connected to said angle ring; an arm, said trunnion means being fixed in said arm; and piston-cylinder means for adjusting said arm vertically and sideways.
Claim 4
Dependent Claim
131 words
An arrangement for marking articles or workpieces with paint or colored dust, particularly hot workpieces, such as coils of sheet metal, with series of symbols individually applied in templates, comprising: a movable angle ring adjustable vertically and sideways and having templates in the form of symbols applied in a cylindrical portion and in a flange-like portion of said movable angle ring; said cylindrical portion being connected to said flange-like portion; a first spray nozzle being located on one side of said flange-like portion and a second spray nozzle being located in said cylindrical portion, said workpieces facing said flange-like portion and said cylindrical portion; trunnion means connected to said angle ring; an arm, said trunnion means being fixed in said arm; and piston-cylinder means for adjusting said arm vertically and sideways.
Claim 5
Dependent Claim
61 words
An arrangement as defined in claim 2 including frame means and driven wheel means; track means, said frame means being movable on said track means by said driven wheel means; said piston-cylinder means comprising a piston-cylinder unit centered in said frame means; lifting table means mounted by said one-piston-cylinder unit, said piston-cylinder means having another piston-cylinder unit connected to said arm.
Claim 6
Dependent Claim
62 words
An arrangement as defined in claim 2 wherein said first nozzle comprises a vertical spray nozzle located above said flange-like portion of said angle ring on the outer end of said arm; said second spray nozzle comprising a horizontal nozzle located on a lower end of said trunnion means tiltable about a horizontal axis inside said cylindrical portion of said angle ring.
Claim 7
Dependent Claim
30 words
An arrangement as defined in claim 2 including container means filled with paint solvents, said first and second spray nozzles being immersible in said container means by auxiliary piston-cylinder means.
Claim 8
Dependent Claim
65 words
An arrangement as defined in claim 5 including a driven pivot arm; said auxiliary piston-cylinder means comprising one piston-cylinder unit connected flexibly to said second spray nozzle and attached to said trunnion means; said auxiliary piston-cylinder means having another piston-cylinder unit for moving said first spray nozzle up and down, said other piston-cylinder unit being attached to said trunnion means by said driven pivot arm.
Claim 9
Dependent Claim
