Definitions

  • the natural pattern of the spray is annular in shape, that is, if a rotating bell-type head of the type shown in said Ransburg application is positioned with its axis of rotation vertically arranged and coating material is supplied to the head for coating a flat sheet located beneath the head, the spray pattern on the sheet would be generally in the form of a circle.
  • relative motion is produced between the head and the sheet so as to apply a homogeneous film of coating material thereover.
  • modified form of atomizing means which can be simply and inexpensivelyconstructed and yet which is quite efiicient in operation.
  • the preferred form of such modified atomizing means is a flat, circular disk of sheet metal or the like which is rotated about its center at a speed sufiicient to spread coating material'delivered to the surface of the disk at'or near its axis of rotation into a thin film outwardly to the edgesof the disk for atomization from an atomizing zone adjacent the diskedge.
  • the disk itself maybe maintained at high electrical potential relative to the articles and thus form one of the electrodes in the'electrostatic coating field.
  • control means for a reciprocating type. of atomizing means as described in the previous paragraph which serves to control the length of the reciprocating stroke of the atomizing means together with readily adjustable means for varying the length of this stroke and for variably determining the top andbottom limits of the'stroke.
  • the arms 44 is extended so as to have an integral portion 51 extending beyond the pivot point 46, which portion carries a rod 52 which in turn carries a microswitch 53 provided with the upper and lower contacts 54 and 55 adapted to contact dogs 56 and 57 adjustably positioned on a rod 58 attached to the support 15.
  • the microswitch is provided with suitable connections 59 to an electrically operated valve 60 which controls the introduction of compressed air into the conduits 49 and 50 from the air pump 61.
  • a method for electrostatically coating a plurality of articles comprising: providing from a source exterior of the article a spray of coating material in a pattern extending radially from said source; bodily transporting said articles successively through said spray pattern in an arcuate path generally concentric with said source and through at least a substantial portion of the spray pattern; and creating an electrostatic charge differential between the spray particles and the articles electrostatically to deposit the particles on the articles while still in liquid state.
