Abstract

The invention is a process and a device for the jigging of a flat can in a textile draw frame. According to the invention, the flat can is subjected to different dynamic moments in the translational movement along the jigging path. It is a characteristic of the invention that the speed is regularly modified in proximity of the reversal points (P1, P2), i.e. in the area of the reversal paths (UW1, UW2). The jigging device is provided with a driving device which renders the constant translational movement changeable in proximity of the reversal point (P1, P2). The driving device may be a servomotor controlled by a computer which serves as the control device. In another embodiment the diving device is a different, less expensive electric motor on the drive shaft of which belt pulleys capable of being coupled are installed.
