Set out thus, the objective of the invention is to avoid shortcoming well known in the prior art.The present invention realizes this purpose by the feature of main aspect.
Because this staggers, thus realized axle that biconjugate puts roller not with the roller of each pair roller between spool mutually opposed.This also provides the space to come the cloth set driver, and this driver needs the installing space of two roller sizes in described two two rollers.
At this preferably, realize being driven the driving of two rollers by independent motor.Advantageously, this independent motor is constructed to synchronous motor.Yet, because the total draft of drafting system is determined to the ratio of the upwards of movement (delivery) of (the withdrawal roller pair) upwards of movement right with importing roller by delivery roller, thereby in many cases, described independent drive motors also can be designed to reluctance motor or asynchronous motor.Middle roller can not exert an influence to the little deviation on upwards of movement or the fluctuation fiber number to the generation yarn.
Under the situation by the two top rollers of independent Motor Drive, the framework of this independent motor (frame) is secured on the connecting rod that is installed on supporting and arm.Under the situation by the two bottom rolls of independent Motor Drive, the framework of this independent motor is secured on the roller bearing bearing of drafting system.
In a modification embodiment, to the driving of two top rollers is via flexible transmission mechanism, especially carry out via cingulum by the axostylus axostyle that driven, this is driven axostylus axostyle and is arranged in the zone of the supporting and the pivotal axis of arm, and is continuous along the length of drafting system.The advantage of this embodiment is that at manufacture view, structure is more simple.Continuously the size of axostylus axostyle is unrestricted, and this axostylus axostyle can be designed to have and not be subjected to the diameter that significantly reverses.
Particularly advantageous is that this continuous axostylus axostyle constitutes the supporting of two top rollers and the pivotal axis of arm simultaneously.In this case, when making progress pivot supporting and arm, the driving connection of extremely two top rollers remains unchanged.
The axle of two rollers that drive unit is applied to it is constructed to fixedly roller, this fixedly roller each roller be connected spool being rigidly connected of they so that driving is driven to two single-rollers.On the other hand, the two rollers that do not driven also can be constructed to fixedly roller or movable (loose) roller.The common driving that the fixedly roller of two rollers that their each roller is subjected to being driven is undertaken by frictional fit.It is configured to fixedly that the advantage of roller is, they will help the synchronous operation between two rollers, this point with independent motor structure for particularly important under the situation of asynchronous motor.
Listed advantage especially is achieved under the right situation of the roller with following apron roller.Thereby, in any case can both this roller on implement the feature of the present invention aspect main.It is right that yet their application and protection domain are not limited to this roller, but can expand to the input roller to right with delivery roller, and it is right also can to expand to other roller.
