  • Patent number: 5937484
    Abstract: A flat container of textile fiber sliver for receiving a sliver produced on a sliver producing textile machine and for feeding the sliver to a sliver processing machine taking over the sliver. The flat container has a movable bottom adapted to move vertically in the flat container, and includes an upper plate arranged adjustably and intended to receive the sliver being deposited, and a lower plate situated under the upper plate and likewise arranged adjustably. The upper plate and the lower plate are mutually coupled by an auxiliary coupling device permitting a common motion and independent motion of the upper and lower plates of the movable bottom.

  • Patent number: 5673461
    Abstract: A method of depositing a textile fiber sliver into flat sliver cans. The sliver is deposited in layers of loops similar in shape to cycloids produced under the action of an inner force effect of the sliver body in the flat sliver can. The force results from the combination of the rotary motion of an outlet aperture of the can coiler and of the mutual reversing rectilinear motion of the can coiler and of the flat sliver can in the direction of the longitudinal axis of the flat sliver can. The axis of rotation of the can coiler lies in the longitudinal axis of the flat sliver can. The width of the layers of the loops in the direction perpendicular to the longitudinal axis of the flat sliver can is inferior to the width of the inner space of the flat sliver can. Thus, a deflection is produced of the sliver loop towards the longitudinal walls of the flat sliver can at which there is a greater velocity of the mutual relative motion of the outlet aperture of the can coiler and of the flat sliver can.
