Rectangular container used in spinning has narrow walls with vertical section of more uniform wall thickness

摘要

The narrow walls (2) at least one vertical section (4) with more uniform wall thickness show which terminates below. Preferred features: The lower edge includes a bulge (6) which is discontinuous with the vertical sections. They are plastic, aluminum and/or vulcanized fibers, and the bulge (6) is metal. The container seen in horizontal section has various cross sections of various wall thicknesses. Its narrow walls are thinner than the long walls. A sheet metal insert is included with a recess against the narrow walls. It has an opening or projection to engage a device gripping and moving the container. A container base can be moved between upper and lower positions and includes fastenings. These comprise transverse and/or longitudinal ridges and/or braces. Spacing between narrow walls and the edge of the base is selected for stability. A positioner locates the base in its lower position; this comprises inter-engaging guides, which are further detailed. Centering devices comprising a transverse rod in the lower region of the container edge are included. A sensor registers filling level, i.e. the vertical position of the container base at various degrees of filling or emptiness. Tilting of the base is registered.
