Abstract
Abstract A method and apparatus for assessing the running behavior of textile machines wherein a yarn monitor detects a characteristic at each spindle and a counter is provided at each spindle to count the number of occurrences at detection of the prescribed characteristic so that an evaluating unit receiving the indications from the counter can provide a signal indicating when a prescribed limit has been reached.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A method of assessing the running behavior of a textile machine including a plurality of spindles comprising the steps of detecting operational characteristics at each individual spindle, counting the detected operational characteristics at each spindle, summing the detected operational characteristics from all of said spindles and generating a signal in the immediate proximity of each spindle when the number or duration of the characteristics detected at the given spindle reaches a predetermined value in excess of the average number of detected operational characteristics of the plural spindles prior to detection of a predetermined total number of operational characteristics from all of said spindles.
Claim 2
Independent Claim
103 words
A method of assessing the running behavior of a textile machine including a plurality of spindles comprising the steps of detecting operational characteristics at each individual spindle, counting the detected operational characteristics at each spindle, summing the detected operational characteristics from all of said spindles and generating a signal in the immediate proximity of each spindle when the number or duration of the characteristics detected at the given spindle reaches a predetermined value in excess of the average number of detected operational characteristics of the plural spindles prior to detection of a predetermined total number of operational characteristics from all of said spindles.
Claim 3
Dependent Claim
21 words
A method as claimed in claim 1 wherein the step of counting is only continued until the said signal is generated.
Claim 4
Independent Claim
117 words
An apparatus for assessing the running behavior of a textile machine having a plurality of spindles comprising yarn monitor means for providing an impulse upon detecting a particular characteristic of the running behavior at each spindle, a counter connected to receive the output of said yarn monitor means at each spindle for counting said impulses representing the occurrences of the detected characteristic at the respective spindle, evaluating means connected to the output of each counter for resetting said counters upon detection of a predetermined total of detected occurrences of the particular characteristic at all of said spindles and signal generator means at each spindle responsive to said counter for indicating when the counter reaches a predetermined count.
Claim 5
Independent Claim
117 words
An apparatus for assessing the running behavior of a textile machine having a plurality of spindles comprising yarn monitor means for providing an impulse upon detecting a particular characteristic of the running behavior at each spindle, a counter connected to receive the output of said yarn monitor means at each spindle for counting said impulses representing the occurrences of the detected characteristic at the respective spindle, evaluating means connected to the output of each counter for resetting said counters upon detection of a predetermined total of detected occurrences of the particular characteristic at all of said spindles and signal generator means at each spindle responsive to said counter for indicating when the counter reaches a predetermined count.
Claim 6
Dependent Claim
14 words
An apparatus as defined in claim 3 wherein said counter includes a bistable multivibrator.
Claim 7
Dependent Claim
27 words
An apparatus as defined in claim 3 wherein said yarn monitor means includes at least one yarn detector which tests the yarn for travel without contact therewith.
Claim 8
Dependent Claim
21 words
An apparatus as defined in claim 3 wherein said yarn monitor means is provided in the form of a yarn cleaner.
Claim 9
Dependent Claim
44 words
An apparatus as defined in claim 3 wherein said yarn monitor means includes a yarn detector at each spindle having its output connected to a respective counter, the outputs of all of said counters being connected to said evaluating means via a common busbar.
Claim 10
Dependent Claim
26 words
An apparatus as defined in claim 3, further comprising relay means for disconnecting said counter from said yarn monitor means upon deactivation of said textile machine.
