To prevent the movement control over a can bottom from affecting the weight of a sliver housed in the can in relation to an apparatus for filling the sliver in the can.

This apparatus for filling a silver 12 in a can 6 is obtained by installing a stationary pressure sensor 29 reactive with a force applied upward by the sliver 12 housed in the can 6 in the apparatus for filling the sliver 12 in the can 6 capable of releasing the sliver 12 from a coiler plate 5 installed in the interior of a supporting plate 26 and housing the sliver 12 in the form of a ring in the can 6. The pressure sensor 29 is capable of feeding a signal for controlling the can bottom 17 movable in the vertical directions to an electronic control regulator 27. The can bottom is moved with an external lifting and lowering device attached to the can 6.
