Abstract
Pressed balls of flocked textile fibers as they are received by the dyer are inserted in a water tight container having inlet and outlet means to circulate dye liquor therethrough, the pressed ball is placed over the outlet opening for the dye which is surrounded by spacer means to space the fibers of the ball from the outlet opening. Additional means are provided to hold the ball against the spacer means. In a preferred form of the apparatus, a unit comprising a plate-like means which contains the spacer means, a central opening to which an outlet pipe is connected and the means for holding the pressed ball against the spacer means, is removable from the water-tight container.
Claims2
In an apparatus for dyeing pressed balls of flocked textile fibers of the type comprising a water-tight container having a liquid inlet opening, a liquid outlet opening and pump means connected to the inlet and outlet openings for circulating dye liquor through the container, and one wall of the container being hinged to provide a watertight door, the improved structure for the dyeing of the pressed balls of flocked textile fibers wherein said container has a cross-section of larger size than the size of the pressed balls to be dyed and comprises pressed ball positioning means consisting essentially of a collar-like spacing ring surrounding the outlet opening, a series of radial spacing ribs extending from the outlet opening towards said spacing ring whereby a pressed ball to-be-dyed can be placed over said outlet opening without blocking the latter, and means opposite said outlet opening for holding a pressed ball to-be-dyed on the spacing ring and radiating ribs, said inlet opening being positioned to supply dye liquor to the space surrounding the pressed ball, said outlet opening for the dye liquor being contained in a plate device containing the collar-like spacing ring which also comprises internal pipe means extending inside the container from the outlet opening towards one wall of the container, connecting pipe means for the internal pipe means extending through one wall of the container, said means opposite the outlet opening for holding a pressed ball on the spacing ring being connected to said plate device.
