Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waxing device for a yarn winding machine such as an automatic wine gourd.

[Conventional technology]

A device is known that waxes the thread by bringing the running thread into contact with the end face of solid wax. For example, there is a method in which a disc-shaped suppressing tray is provided opposite one end face of a cylindrical wax sock, and the thread is run while being nipped between the wax and the presser to apply wax.

[Problem that the invention seeks to solve]

In various types of devices, including the above-mentioned waxing device, what is important is that wax is evenly attached to the thread throughout the system, that is, controlling the running position of the thread,
The purpose is to ensure that the surface of the wax that comes into contact with the yarn is worn evenly over the entire surface, and that fluctuations in tension during yarn travel are minimized.

The above waxing is performed to improve the passage of the knitting needles through the needle holes when used in the knitting machine in the subsequent process. Also, the thread passing through becomes poor, and extremely delicate adjustment of the adhesion amount is required.

Furthermore, in order to satisfy the above-mentioned demands, it is necessary that the device be compact without increasing its size.

The present invention provides a waxing device that solves the above problems.

[Means to solve the problem]

The present invention provides wax application having a pre-tensioning device, wax that actively rotates, and a position regulating member for regulating the thread running path on the end face of the wax, on a base that is detachably attached to the weaving main body. It is equipped with a device.
