Apparatus for supplying a definite amount of a treating liquid to a textile product continuously

An apparatus for continuously applying a definite amount of a treating liquid to a textile product comprising a liquid retaining roll having a surface for retaining a treating liquid thereon, a rubber roll disposed in pressure contact with said liquid retaining roll for forming a bite therebetween and said rubber roll arranged to guide the textile product to the bite so that the textile product is pressed against said liquid retaining roll for transferring a definite amount of the treating liquid to the textile product, said liquid retaining roll being rotatable about an axis, said rubber roll being rotatable about an axis in generally parallel relation with the axis of said liquid retaining roll with said rubber roll and liquid retaining roll rotating in opposite directions, a vessel located on the opposite side of said liquid retaining roll from the bite between said rubber roll and liquid retaining roll and being angularly spaced from said rubber roll, said vessel having a bottom surface sloping downwardly toward the surface of said liquid retaining roll, said vessel being arranged to contain a body of the treating liquid so that a treating liquid level is located within said vessel above the bottom thereof with the body of treating liquid contacting the surface of said liquid retaining roll, said vessel being open along the side thereof extending in the axial direction of said liquid retaining roll and adjacent said liquid retaining roll, said vessel having a length of said side so that the treating liquid therein flows out of said vessel at the opposite ends of said retaining roll for eliminating flock, hards and dust adhering to said liquid retaining roll, a doctor roll disposed in pressing contact with said liquid retaining roll and being angularly spaced from said rubber roll and said vessel so that said liquid retaining roll rotates through said vessel and contacts said doctor roll before contacting said rubber roll, and means for cleaning the surface of said rubber roll, said means including means for directing a part of the treating liquid against the surface of said rubber roll at a position angularly spaced from the bite between said rubber roll and said liquid retaining roll.
