Abstract:
A splatter blocking apparatus for use in a flame spray system, said apparatus comprising: (a) a barrier member adapted to be moved between a blocking position in which said barrier member is extended across a spray path from a flame spray gun of a flame spray system preventing travel of particles of fusible material from the flame spray gun to a product being coated and an unblocking position in which said barrier member is displaced from the spray path of the flame spray gun permitting travel of particles of fusible material from the flame spray gun to the product being coated; and(b) an actuation mechanism connected to said barrier member and adapted to be selectively actuated to move said barrier member between said blocking and unblocking positions, said actuation mechanism including (i) a stationary member mounted in a stationary position alongside the flame spray gun and having a longitudinal axis and a guide element extending along and in an arcuate path at least partially about said axis; and (ii) a movable member mounted to said stationary member to undergo axial movement between forward and rearward axial positions relative to said stationary member along said axis of said stationary member, said movable member having a follower element engaged with said guide element of said stationary member such that upon axial movement of said movable member between said forward and rearward axial positions, said follower element moves along said arcuate path of said guide element in thereby causing corresponding rotational movement of said movable member between first and second rotational positions relative to said stationary member.
