2. Description of the Related Art The most popular sock finishing apparatus for automatically finishing a sock with steam is a steam set in which a sock is mounted on a last that moves on a circumference and the middle of the last is moved. The set is subjected to a setting process, then the drying process is performed by a heater of a drying oven, and then the socks are removed from the last at the extracting portion.

[0003]

When the socks are automatically set and finished, a visual inspection of good and defective socks is required before the finishing process. Conventionally, a visual inspection is performed separately from the finishing process. Therefore, there is a problem in that the number of work steps is increased correspondingly, and the work cost is increased by the inefficiency.

In the finishing of socks using a last, it is preferable to provide a heel at the upper part of the last and set the toe of the sock in the shape of the heel. Because it becomes a shape inclined with respect to the vertical axis, it becomes difficult to perform the mounting and removing work of socks smoothly,
There is a problem that the setting from the heel to the toe cannot be performed accurately.

It is an object of the present invention to provide a series of visual inspection and finishing steps for socks, and from a heel to a toe.
It is an object of the present invention to provide a sock finishing apparatus capable of reliably performing the operation from the heel portion to the toe portion setting of the sock by automating the operation of attaching and removing the sock to the last with the inclined portion.

Becomes freely is rotated along the inclined direction of the portion, the vertical movement and the rotation thus withdrawn socks from test template is then obtained by adopting the configuration of arranging the sock mounting mechanism for mounting the foot shape.

[0007] The second invention is a two-sheet 1
Socks in which a pair of lasts are arranged to move intermittently along a circumferential track, and are inclined at the top of the lasts that stop at the sock removal position so as to correspond to the shape of the heel to the toe of the lasts. The extraction mechanism is arranged to move up and down along the direction of the toe from the heel, and the pair of extraction rolls provided in the sock extraction mechanism sandwiches the last, so that the extraction roll follows the shape of the last. The sock is removed from the last by moving it.

[0008] A pair of fold plates for folding the panty portion of the sock attached to the last into the inside are movably attached to the lower position between the opposing lasts, and the inner edges of the fold plates are corrugated. It can also be formed in a shape.

[0009]

[First invention] In a state where the sock mounting mechanism stands by at the ascending position, the sock is inserted into the pair of inspection templates from below and mounted, a visual inspection of the sock is performed, and after the inspection, the sock mounting mechanism is lowered. The sock is removed from the test template and held, and then moved up.The sock mounting mechanism makes one turn at the ascending position. Thus, the socks attached to the inspection template can be automatically transferred to the last.
