  • Patent number: 10301755
    Abstract: A wet treatment device (1) for the wet treatment of textile making-ups (T) has a treatment drum (10) which is driven about a vertical axis of rotation (A) in a direction of rotation (V) by a rotary drive. The treatment drum (10), which can be loaded at the top, has a drum shell (13) arranged on the circumferential side relative to the axis of rotation (A) and having an outlet opening (20). The latter opens into a return line device (30) which is arranged to be fixed against rotation and which has an annular channel (32) enclosing the treatment drum (10) radially and formed so as to be open in the direction of the outlet opening (20). In addition, the return line device (30) has a discharge opening (31), which is positioned above the drum base (11) and closer to the axis of rotation (A) than the first outlet opening (20).

  • Patent number: 4150448
    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.
