JPS6011099Y2 - Traveler for spinning machine - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to the structure of a traveler for a spinning machine.

Conventionally, an insert resin traveler is known in which a steel or other hard metal 3 is inserted into the thread contact portion 2 of a resin traveler 1, as shown in FIG. 1, in order to improve layer resistance against threads.

However, with the above-mentioned insert resin traveler, the sliding posture of the traveler fluctuates when passing through nep and knots during spinning, which induces fluctuations in yarn tension, causing yarn unevenness and yarn breakage, resulting in inconsistent quality. There were drawbacks.

Another drawback is that fibers that are wrapped around the insert during use are difficult to escape due to its structure.

The present invention eliminates the above-mentioned drawbacks and provides a traveler for a spinning machine that provides stable gliding to produce high-quality yarn and is easy to handle.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows a traveler for a spinning machine according to the present invention.
The insert member 8 is made of steel and has a continuous curved bulge in the upper and back directions.

The lower end of the upper half of the traveler consisting only of the insert member 8 is formed of nylon resin, and is inserted and fixed into the lower half of the traveler, which is the sliding part 6 with the ring.

In addition to steel, the insert member 8 may be made of various hard metals depending on the intended use, and the resin may be nylon or various thermoplastic resins depending on the intended use.

Since the traveler according to the present invention configured as described above has a bulge in the thread contacting part 5 following the flat part of the head 4, there is a bulge between the ring and the traveler when spinning decorative threads such as nep yarns and loop yarns or when twisting general yarns. Prevents the yarn end from being pinched or causing fluctuations when the yarn passes through nep or knots, thereby preventing gliding disturbances.

In addition, even if the contact position of the head with respect to the ring changes in a forward leaning or twisting posture when the traveler travels, the traveler travels stably because it is formed in a straight plane and is not easily influenced by the state of burring.

Furthermore, the main sliding contact portion with the ring is made of resin, which, in combination with the shape of the upper portion of the traveler, prevents thread breakage and thread staining, making it possible to obtain high-quality thread.

In addition, unlike conventional insert resin travelers, the head is not provided with a molded resin part 7, but is made of a metal wire with a circular cross section, so it has excellent features such as being able to easily remove the fibers that are wound during spinning. It is effective.
