Abstract
Combing machine. The combing machine includes a process control computer for the preparatory machine of a textile spinning mill, the former being located upstream of a combing machine which reacts to signals from the combing machine, which signals are representative both of the evenness of feed material supplied to a controlled drafting arrangement as well as of the comber waste share, with the computer producing a signal which is indicative of a change in the evenness behavior of the machines located upstream of the combing machine when the evenness of the feed material changes while the comber waste share remains unchanged. A method for operating the combing machine is also set forth.
Claims21
A combing machine with a fiber mass measuring device arranged after the combing heads of the combing machine, the combing machine being in combination with other fiber processing machines located upstream of the combing machine, the combing machine comprising:
- means for determining the comber waste occurring in the combing machine;
- and
- means for generating a signal representative of the evenness behaviour of the fiber mass being supplied to the combing machine, the signal-generating means being responsive both to the fiber mass determined by the measuring device as well as to the determination of the comber waste, so that a change in the evenness behaviour of the fiber processing machines located upstream of the combing machine is only deduced in the event that the comber waste share remains within preset tolerances while the evenness of the fiber mass as scanned by the measuring device changes.
A method for a combing machine with a fiber mass measuring device arranged after the combing heads of the combing machine, the combing machine being in combination with other fiber processing machines located upstream of the combing machine, the method comprising:
- monitoring both the evenness of the fiber material supplied by the combing heads of the combing machine as well as the comber waste share;
- and
- forming a signal representative of a change in the evenness behaviour of the fiber processing machines located upstream of the combing machine when the evenness of the fiber material being monitored changes while the comber waste share remains unchanged.
