ABSTRACT:
The present invention relates to devices for placing sliver in a can and can be effectively used in high-speed draw frames with sliver delivery speeds as high as 200 m/min and even higher. The device comprises a rotatable can with a movable bottom that can be lifted and lowered by means of a flexible rod made up of several portions. The upper portion of the rod includes the rotatable base for the movable bottom, the intermediate portion thereof is a flexible and has with bearing abutments, while the lower portion of the rod is a carriage coupled with the rotatable support via a flexible but non-stretchable tensioned member which is kept in permanent engagement with the bearing abutments, to provide for an adequate rigidity of the flexible rod portion when the latter either lifts or lowers the movable bottom.
