Knife coaters (KOR)
Dual Knife Over Roll coating line | Thick coating application | High capacity flotation for specially heavy substrates | Solvent base coating with coater enclosures | Multizone flotation dryers
This knife over plate latex foam applicator is used in the automotive industry to apply a foam backing to carpet. The coating distribution unit stroke can be adjusted manually to disperse the latex uniformly between the two side dams.
The knife over roll coater is typically used for applying relatively thick and more viscous coatings to various types of substrates such as textiles and nonwovens.
This method uses mirrored knife-over-roll coater heads mounted horizontally. The first head is mounted in a fixed position; the other is mounted in dove tails with a manual wedge block gap adjustment mechanism on each side. The web will pass vertically down between the two applicator rolls such that the coating will be applied and squeezed on each side of the web simultaneously.
