Abstract (en)
[origin: WO2013182260A1] The invention relates to a device on a combing machine, comprising a drive device for producing a "pilgrim step" motion for the detaching rollers of said combing machine, said device comprising a first electric motor that rotates with a uniform motion and a second electric motor which rotates a shaft, the second shaft carrying components for transmitting the motion to the detaching rollers. The first electric motor also acts on some of the components of the control gearing which transmits the motion to the detaching rollers, and the second motor is equipped with operating means which are subject to a unidirectional law of motion with acceleration and deceleration phases. Both the first and the second motor are in engagement at all times and rotate continuously in the same direction, and their rotational motions are combined by a differential device to obtain a resulting "pilgrim step" type motion on the detaching rollers. To allow an increase in the degree of freedom in the form of the motion curve of the detaching rollers, as well as greater combing machine efficiency, the second electric motor is a servomotor which transforms a uniform motion of the first electric motor into an non-uniform rotational motion, and which is connected to an electronic control and/or regulation device.
