A device for controlling the bobbin drive of a flyer roving frame which has a bobbin, a flyer and drive roll thereon that are utilized for building a bobbin with yarn. A drive for the frame incorporating a differential gear and controls are provided for adjusting the driving speed of the flyer and drive roll stepwise to different rotational speed stages during the building of the bobbin. An additional speed adjusting device is provided for automatically varying the driving speed of the bobbin within each rotational speed stage. A switching device is provided for automatically switching the rotational speed stages.

The present invention is directed to a drawframe having a sliver delivery device and a computer part for maintaining a predetermined quality of sliver, wherein there is a predetermined overproduction from a card and/or a drawframe relative to a spinning machine. The arrangement temporarily decreases production to temporarily compensate for the overproductions. The sliver which is produced during the decrease in production may be delivered to a separate can.

A device for controlling the output speed of a motor of a ring spinning machine, a ring twisting machine and the like in case of replacing travelers of such machines includes a speed setter for the motor and a potentiometer which is operatively connected with the speed setter to limit the output speed of the motor for allowing breaking in of replaced travelers. The potentiometer is further coupled with a speeding-up unit which is e.g. a stepper motor and which over a selected period of time increases the limited output speed to the normal operating level by automatically resetting the slider of the potentiometer from one end position to another end position.

The invention concerns an apparatus for controlling the rotational speed of the spindles of a spinning preparatory machine equipped with spindles and flyers.The proposed control arrangement comprises an infinitely variable variator, which is adapted or adjusted by using a control shaft which is rotatably indexed or stepped. The control or adjustment shaft is moved by a control motor which received its control or switching impulses from a motor control device comprising a programmable indicator or set value transmitter for the desired or set value and a correction element.According to a particularly advantageous design the correction element is of the form of a crossbar distributor arrangement.The apparatus is comfortable and easy to use by the operating personnel and permits, among other advantages, extremely accurate adaptation or adjustment of the spindle rotational speed. The adaption operations can be effected while the machine is running.
摘要:
A textile machine with switchable multistage gearing for the adjustment of the turning speed ratio between rotating parts of the textile machine, such as drives, spindles, delivery members, stretching members, and the like, having a control system for switching the respective couplings of the multistage gearing upon a command from a decimal feed-in means having the capability of storing the desired fed in turning speed ratio. The decimal input is converted into a binary coded signal independent of time and compared in a comparison stage with pre-programmed signals representative of settable turning speed ratios.
