Abstract
A sliver coiler apparatus includes a machine frame; a stationary coiler plate supported in the machine frame; a coiler head rotatably supported in the coiler plate; a platform situated underneath the coiler plate; a coiler can positioned on the platform and having a vertically displaceable can bottom; and a control assembly for controlling a rate of downward movement of the can bottom. The control assembly includes an electronic control device; a mechanism for lowering the can bottom; and a pressure sensor responding to forces exerted by the sliver as the sliver filling operation proceeds. The drive of the lowering mechanism and the pressure sensor are connected to the electronic control device which controls the rate with which the mechanism moves the can bottom downwardly as a function of the signals generated by the pressure sensor.
