Abstract
Abstract This machine for spray painting hides, cardboard, and the like, while being carried on a moving blanket, comprises spray guns mounted in-line transversely to the blanket and adjustable simultaneously, as well as being easily installed and interchangeable. For a uniform distribution of the paint being sprayed, the spray gun jets are swept by jets or sheets of air issued from nozzles reciprocating with at least one component transverse to the blanket direction of movement. Moreover, the machine is equipped, in the proximities of the spray line, with nozzles for generating air sheets which have the function of trapping onto the workpiece the fumes rebounding from the spraying process.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A machine for spray painting a material being carried on a blanket, comprising a plurality of spray guns arranged above said blanket characterized in that said spray guns are arranged fixedly along a line extending transversely to the blanket direction of movement, that there is provided a plurality of nozzles associated with said spray guns for sending jets of fluid or air against the area being spray painted, and in that said nozzles, whose direction has a major component in the spraying direction of the spray guns, are mounted on a structure reciprocable with at least one component transverse to the direction of movement of said blanket, thereby making the issuing sprays more uniform and broader.
Claim 2
Dependent Claim
116 words
A machine for spray painting a material being carried on a blanket, comprising a plurality of spray guns arranged above said blanket characterized in that said spray guns are arranged fixedly along a line extending transversely to the blanket direction of movement, that there is provided a plurality of nozzles associated with said spray guns for sending jets of fluid or air against the area being spray painted, and in that said nozzles, whose direction has a major component in the spraying direction of the spray guns, are mounted on a structure reciprocable with at least one component transverse to the direction of movement of said blanket, thereby making the issuing sprays more uniform and broader.
Claim 3
Dependent Claim
43 words
A machine according to claim 1, characterized in that said nozzles are mounted on a bar movable transversely to the direction of movement of said blanket and driven through a connecting rod and crank mechanism by a motor of the variable speed type.
Claim 4
Dependent Claim
19 words
A machine according to claim 1, characterized in that it comprises two sets of nozzles arranged in converging directions.
Claim 5
Dependent Claim
27 words
A machine according to claim 1, characterized in that said nozzles are supported for a pivotal movement about a perpendicular axis to the direction of said nozzles.
Claim 6
Dependent Claim
29 words
A machine according to claim 1, characterized in that said nozzles have an outlet port located substantially at an intermediate height level between said spray guns and said blanket.
Claim 7
Dependent Claim
46 words
A machine according to claim 1, characterized in that it comprises at least one box provided with slots for blowing air through the whole width of the machine at least downstream of said nozzles and trap onto the workpiece the fumes rebounding from the spray jets.
Claim 8
Dependent Claim
22 words
A machine according to claim 1, characterized in that said spray guns are arranged on a box-like crosspiece with height adjustment features.
Claim 9
Dependent Claim
72 words
A machine according to claim 1, characterized in that said box-like crosspiece is provided, for each said spray guns, with pigment or paint and air intake conduits, and that said spray guns are sealingly attachable to said box-like crosspiece, the conduits of said spray guns being aligned with said intake conduits by means of locating pins and notches, a lever and cam system being provided for locking said spray guns in place.
Claim 10
Dependent Claim
86 words
A machine according to either claim 8, characterized in that said box-like crosspiece is further provided, for each said spray guns, with a pressurized air supply conduit to produce the displacement of a piston engageable with a rod for adjusting the amount of pigment or paint being delivered, the travel limit of said piston being adjustable by means of a spiralling profile cam, the cams of all said spray guns being made rigid with a common rod for the simultaneous adjustment of all said spray guns.
Claim 11
Dependent Claim
37 words
A machine according to claim 8, characterized in that said intake conduits have respective adjustment and opening valves associated in said box-like crosspiece, the corresponding valves of all said spray guns being simultaneously controllable to equal extents.
