JPS5829096Y2 - thread winding bobbin - Google Patents

Description

[Detailed description of the invention] The bobbin with the initial winding required for several yarn splicings is carried out on an empty bobbin, and the bobbin with the above-mentioned initial winding is supplied to the yarn measuring machine as a yarn taking bobbin, and the automatic yarn of the yarn measuring machine is The method of restarting the initial winding yarn and the splicing yarn amount by the splicing device is convenient for automatic bobbin supply and automatic yarn amount resumption.

However, the above-mentioned bobbin has drawbacks such as the initial amount system unraveling at a storage location or the like during transportation and becoming entangled with threads from other bobbins.

The present invention solves the above-mentioned drawbacks, and after the initial punch winding 2 is performed on the end of the empty bobbin 1, the yarn is automatically spliced several times using a traverse device such as a traverse guide or a traverse drum. The necessary amount of yarn is wound as an initial winding 3, and furthermore, a punch winding 4 is performed on the initial winding, that is, within the traverse range 5, with a yarn amount smaller than the yarn amount required for one yarn splicing.

The present invention is characterized in that the punch winding 4 makes it difficult for the yarn on the bobbin to unravel, and prevents the occurrence of a situation in which yarn splicing is impossible due to the yarn path unevenness or decrease in the yarn yarn amount on the bobbin. By being placed at a fixed position within the range, the yarn end is reliably suctioned by the yarn search suction mouse when the metering system is interrupted, and the automatic yarn splicing operation is ensured.

In particular, when the suction mouth has a small diameter that does not have the width of the full length of the twill, this is particularly effective in ensuring the above-mentioned thread search system effect.

[Scope of utility model registration request] After the initial traverse winding is performed on the empty bobbin in an amount necessary for several thread splices, punch winding is performed within the traverse range with a smaller amount of yarn than necessary for one thread splicing. Features a thread measuring bobbin.
