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.

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.

Abstract: A method and device for exchanging sliver containers on a sliver producing textile machine, particularly non-cylindrical containers, wherein the containers are supported on a support and are moved in a direction, perpendicular to their long axis past the coiling device. A respective shifting frame for the container to be filled and the adjacent container. The shifting frames grasp the two containers, raises them and enables the coiling device to fill the one container, then moves the containers to exchange the filled container for an empty one, and lowers the containers back to the supporting conveyor, wherein the sequence of filling and raising is selectively variable. The device carries out the foregoing steps. A non-circular sliver container has handles on opposite sides, particularly on its long sides, for being grasped by carrying means on the shifting frames of the device for raising and moving the containers. The handles may be holes in the container or recesses with bearing surfaces.

Abstract: A device for severing the sliver in a filling station for cans of a textile machine producing the sliver, upon the replacement of a full can by an empty one. The filling station comprises a sliver coiling device on which there is mounted, over the gap between the transferred full can and the can just beginning to receive the sliver, a sliver holding device and also a sliver grasping device which is reversibly movably mounted on the coiling device for the sliver to move with reference to the sliver holding device thereby to sever the sliver held between the grasping and holding device by movement of the grasping device.

Abstract: Method of manufacturing core yarns from fiber bands. A part of the fibers of a fiber band is released from the fiber band and is deflected. These deflected fibers do not participate in the spinning process, but are wrapped around the twisted core in a plurality of reinforcing winds. The method of the invention overcomes the problems of manufacturing yarns without requiring expensive and complicated mechanical elements.
