[Title of the Invention]
Process for determination of the running speed of thread and estimating the number of
false-twists in false-twisting machine
[Claims]
1. Means for measuring the running speed of the tread (Y) by running said thread (Y)
through two capacitance type detector heads (1a, 1b) spaced at specified distance L,
through L/T operations of the time for the twist to pass through one head and arrive at the
second. (See Figure 1)
2. Means of obtaining the running speed of the thread Y, and based on the this information,
to estimate the false-twisting number of the thread Y, as the thread runs through the two
capacitance type detector heads (1a, 1b) spaced at a specific distance L, while being
twined, and the time T required for the twist of thread Y detected at one head and until it
reaches the second is processed through L/T operation.
[Excerpt from Detail Description of the Invention and Drawings]
This invention concerns the detection of the funning speed of the thread without physical
contact with the thread itself. Applying the specified process on false-twisting machine and
measuring the running speed of the thread in false-twisting stage, enables estimation of the
number of false-twists in the running thread Y. The usual process of measuring the running
speed of the thread is by contact with a roller and obtaining the number of its spin, but this
processesometime affected the running of the thread or caused the thread to break.

[Explanation]
The technical fields of the specified invention (Claim 1) and related invention (Claim 2) are
in “the measurement of the running speed of the thread” and “estimation of false-twists in the
thread", respectively. The measured running speed of the thread, however, is used to estimate
the number of false-twists in a thread, the two inventions are technically and directly related,
and the industrial fields of application of both inventions are the same.
The substantial part of the measurement of the running speed of the thread that is the
new matter corresponding to the problem to be solved of the specified invention (Claim 1) is
substantial part of matters in the claim of the related invention (Claim 2). Therefore the
substantial parts of matters in the claims of the inventions are the same.
