ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to the art of sliver compression methods and devices. It allows sliver to be freely loaded onto a plate without having restrictions around the entire circumference of the sliver that is loaded onto the plate where the sliver will then be compressed. This invention relates to the compression method of sliver and how it is loaded on the plate-like sliver tray without restrictions on the entire circumference of the loaded sliver.
BACKGROUND OF THE INVENTION
The common industrial method currently in use is to take sliver spun out of the drawing frame and to place it on a tube-like spindle with a bottom. This patent applicant has previously applied for patents by developing the accommodation method which allows for accommodating the spun out sliver onto a plate-like sliver tray instead of using spindles (Japanese Patent Application 11-54930 and Japanese Patent Application 11-99550). When using the conventional spindle method, the accommodated sliver will be compressed to reduce the entire volume because the external circumference of accommodated sliver is in contact with the internal circumference of the spindle with a designated pressure.
The previously applied for patent methods occurred without using a spindle and created a non-restricting condition on the entire external circumference. The previously applied for new methods did not help prevent the sliver (which consists of fibers) from reversing back to their original shape as shown in FIG.

, both had a low density and a high volume and without adequate control both were unstable. These factors can cause various troubles including the possibility of collapse while transporting the loaded sliver to the next process. In addition, the previous methods required a large storage space in which to store the spindles.
SUMMARY OF THE INVENTION
This invention presents a new method and device of compressing loaded sliver onto a plate-like sliver tray after being accommodated by the non-spindle method to reduce the volume for easier handling in preparation for the next process.
