This invention relates to seamless hosiery and more particularly to seamless hosiery knit‘ of a ' thread formed of a material such for example as the synthetic ?bre forming polymeric amides (Cl. 66-1) shown as are necessary to clearly illustrate the invention. In the drawings, Figure 1 is a partial view in side elevation of known as “nylon” which is adapted to be set to 5 a‘knitting machine in accordance with this in r. a de?nite shape by subjecting the material to vention, parts being broken away to'show other ' heat or heat and moisture as in the hosiery pre parts more clearly; boarding operation. In order that the hosiery Figure 2 is a view in front elevation of the may be properly shaped by the preboarding op knitting machine head shown in Figure 1, parts eration it is necessary that the hosiery be placed 10 being broken away to show other parts more on the preboarding form with particular wales clearly; at the back and front of the hosiery exactly fol Figure 3 is a partial plan view of the knitting lowing the back and front edges, respectively, of machine shown in Figure 1, parts being broken the thin ?at form used in this operation. In away to show other parts more clearly; boarding full-fashioned hosiery the seam at the 15 Figures 4 and 5 are vertical sections through back and bottom of the hosiery provides a raised the needle cylinder taken at different places so‘ guide enabling the operator to rapidly and accu as to show different phases of the jack and nee rately position the hosiery on the boarding-form dle operation, Figure 4 showing the operation of by placing the hosiery seam along the back edge a jack for a needle other than those at the wales of the form, an Operation which can be carried 20 to be placed on the preboarding form edge while ‘ out by feeling the position of the seam on the Figure 5 shows the operation of a jack for a nee form. With seamless hosiery there is no seam dle‘ at a wale to be placed on the form edge; to guide the operator and in order to place seam Figure 6 is a perspective view of part of the less hosiery on a boarding form so as to have the operating means for applying coloring material _ hosiery present the most attractive appearance 25 to the needles knitting the wales to be placed on when offered‘ for sale it is necessary to place par the preboarding form edge; ticular wales of the hosiery on the back and front Figure 7 is a fragmentary plan view showing edges of the form.

It ‘is an ob coloring material applied in accordance with this ject of this invention to provide seamless hosiery ' invention; and Y of the class described having means for guiding Figure 10 is an enlarged view of a fragment of the positioning of the hosiery on the forms for 35 the hosiery fabric showing the coloring material the preboarding operation.v It is also an object applied to two wales. of this invention to provide a method of placing As shown in Figures 8 and 10,'hosiery in ac the guiding means on the hosiery during the cordance with this invention has a guide mark knitting thereof such that the. guiding means M of a width of one or more needle wales extend will correctly indicate the proper wales to be 40 ing down the center of the back of the leg L alined with the edges of the form and it is a fur ther object of this invention to provide a knit from the welt W to the heel H.

Preferably nection with a Scott and Williams circular knit the guide mark is formed of fugitive dye con ting machine for-knitting hosiery having turned trasting sufficiently in color with the thread of welts, the machine being of the general construc which the hosiery is knit to be readily seen when 50 tion shown in the patent to Scott, No. 1,282,958, the hosiery is being placed on the preboarding issued October 29, 1918, and provided with pat terning mechanism comprising jacks and jack selecting means such as are shown in the patent form.
