Sandwich Screens are designed to keep the mesh-free from obstruction from materials by applying gentle vibration against the bottom of the screen with a combination of either Nylon Sliders and/or Rubber Balls. These components gently rotate around the screen to provide even coverage for the entire screen. The sandwich screens are an easier solution to manage than clean ring assemblies and ball trays as the de-blinding sliders and balls are contained between both layers of mesh. This allows for faster screen changeout for cleaning or production run changes.
Epoxy-bonded mesh sandwich screens can be returned and re-screened often many times before the sliders and balls and support mesh needs to be replaced, which is significantly less costly than purchasing new screens.
Note that for 18 ", 24”, 30”, 36”, and 40” screens we do not recommend using any kind of center spacer or support. If you feel that you need one for one of these sizes, please contact us for appropriate design and pricing.
