Abstract
Abstract An automatic device for spraying powdered resin onto coils of a motor or similar electrical devices comprising a shaft that is rotatable horizontally and movable axially, comprising at least one nozzle on one end of the shaft for spraying a powdered resin on a coil located adjacent the noxxle, means for rotating the shaft, and means for moving the shaft axially, whereby the nozzle may be automatically rotated around the coil and moved longitudinally thereof to deposit a predetermined thickness of a coating of powdered resin on selected areas of a coil.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
79 words
A device for applying a coating of a powdered resin to an object comprising 1. a supporting frame; 2. a rotatable member mounted on said frame; 3. means for rotating said rotatable member; 4. means for reciprocating said rotatable member alonG its axis; and 5. at least one inwardly-directed and at least one outwardlydirected powdered resin-spraying nozzle connected to said rotatable member, each radially spaced from said axis, whereby said nozzles move simultaneously in a reciprocating and circular path.
