Method and apparatus for altering angular velocity of a coiler head

摘要

An apparatus for depositing sliver from a sliver-producing machine into a coiler can in an annular pattern includes two cooperating pressure rolls for advancing the sliver; a rotatably supported coiler head arranged for receiving sliver from the pressure rolls and having a sliver outlet travelling in a circular path upon rotation of the coiler head; a movable coiler can platform disposed below the coiler head for receiving a coiler can in an upright position; a drive for driving the pressure rolls, the coiler head and the coiler can platform for advancing sliver from the pressure rolls into the coiler head and for depositing sliver by the circulating sliver outlet into the coiler can moved by the coiler can platform in an annular pattern; and a control and regulating device connected to the drive for altering the angular velocity of the coiler head within revolutions thereof as a function of momentary positions of the sliver outlet on the circular path thereof.
