ABSTRACT:
A dye beam for a roll of convoluted textile material has a foraminous tube whose end portions extend beyond the axial ends of the roll and whose apertures admit dye fluid into the roll in response to admission of pressurized fluid into its interior. A circumferentially complete or spirally convoluted impermeable elastic sleeve surrounds each end portion of the tube and the inner end of each sleeve is confined within the roll. The outer ends of the sleeves are sealingly clamped to the external surface of the tube and the inner ends of the sleeves are held against appreciable movement away from each other so that they remain within the confines of the roll. To this end, the inner ends are connected to each other by bands or by a foraminous hose, the inner ends are anchored in the tube, the inner ends are bonded to or interleaved with the end cloth which is convoluted around the tube within the roll, or the exposed portions of the sleeves are surrounded by annuli of plates which are pivoted to the axial ends of the tube and are overlapped by the end portions of the end cloth. When the pressurized dye fluid issues from the tube and penetrates into the roll, some of the fluid causes limited radial expansion of the sleeves; however, the sleeves prevent escape of dye fluid by a route other than through the roll.
