For this reason the inventor desires -to completely have the cam surface of the stitch density adjusting device able to perform a gentle adjustment in various degrees, as set for-th in the presen-t embodiment.
Three kinds of yarn are used for the knitting yarn:
Pile yarn P and ground yarn F are used as plaiting through one knitting needle and/ in addi-tion, elastic yarn E is inserted through the Eormer yarns, when knitting a rib stitch type of stretch zone. The blended yarn used as pile yarn P consists of staple fiber belonginy to the acrylic synthetic fiber family (75% in blend levell, staple fiber belonging to the polyamide synthetic fiber family (20%~ and wool fiber (5%1. The ground yarn ; is long covered staple belonging to the polyurethane synthetic er family~ In the present embodiment, the elastic yarns El and E2 employ polyurethane synthetic long ~iber, small in count.
El~ thicker, i~ applied with stronger tension, ~hereas E2, thinner is applied with weak tension. The ground yarn F' illustrated in Fig, 2 ~s preparatory ra~ yarn, FigO 1 is a perspective view illustrating the state in which the tigh-ts of the present invention is turned over, I is the stretch zone for ankle part, Fig. 4 is a structure Yiew illustrating the state in whIch a lower end of the above zone staxts to be knitted, II is a plain knitted zone for lower part of leg and the structure in which it is knitted is illus-trated in F~g. 5. III is a r~ised zone tor thiyh par-ts and the s-truc-ture 3~6~

Their knitted struc-tures employ the same stretch zone as -that for -the ankle part I. II' is a gusset and its knitted struc-ture employs the same plain knitted zone as that for the lower part o~ lecJ II.
Furthermore, III' is an upper part of the leg, III" is a knee part and their knitted s-tructure employs the same raised zone as that for the thighs III~
The ~round yarn F and the pile yarn P, which serve as plaiting, and the rib stitch structure through which the elastic yarn is inserted constitute the stre-tch zones I, I', and I". On the other hand the stretch zone for the ankle part I fastens the : lower part of the tights by means of applying weaker tension to the elastic yarn E2 which is large in count, whereas the stretch zones on the upper and lower parts of knee are a~ap-ted to firmly fasten them to the extent of tightening spots on them so as to produce the supporting effect.
The direction in which the knitting process commences to be.performed frc~m the low.er end of ankle is sho~n by b in Fig.
4 and an upper position toward which an advancement of the knitt-ing is made is shown by t~ Three strands of E, E', and E" are used as elastic yarns which are inserted throug~ the part to be kn~tted on the lower end of the ankle thereb~ making it difficult for the fabrics about it to be loosened.
The plain knitted zones II and II' are composed of a ~nitted combination between the ground yarn F and the pile yarn P which serve as plaiting, A back sur~ace of the plain knitted zone for the gusset III is permitted to employ such a knitted structure as a raised zone, Fiy. 6 illustrates the knitted struc-ture o~ the raised zones III, III'~ III", C is a course direction in which a 1 knitting machine rotates and W is a vertical row in w.hich knitting-up .is performed, The sinker loop device S shown in Fig~ 2 adopts the structure in which ~ thin steel sinker 6 is inserted through the needle groove (no-t shown~ of a sinker ring 8, provided rad-ially with respect to the center of the movable ring R of -the sinker, and sinker cam ring 9, located a-t -the rear and upper end of the sinker 6, is equipped with a projec-tion part 9a in-terlocked with the sinker b at the top end thereof, whereby an advancement and a retreat of the sinker cam ring 9 shall permit the sinker 6 ~o to move forward and backward respectively.
A nib 6a is mounted on the top end of the sinker 6.
The ground yarn F i.s put on the lower part of the nib 6a and the pile yarn is put on the upper part of the nib 6a so that the pile system P forms a pile on the inner surface oE the knitted fabrics.
At that time, if a spring 3 and the stationary brush are actuated on the inner surface of -the knitted fa~ric~ made on the upper part of the movable ring R, the top part of the pile produces the .raising phenomenon N in the course direc-tion C. This method solves the defect of the conyenti`onal process that the fabrics, remoyed from the knitt~ng machine, which is raised hy a separate raising machine, gets its raising in a vertical row non-uniformed and disappearing due to being caught wi-th a loop, and can obtain the raising N which is long in pile and without stripel The method of the present invention i5 to be advanced in the sequence of first commencing to knit that ankle part at the stitch.density for the ankle 4a, continuing to perform knitt-ing hy means of rotating a control drum D in the arrow direction shown in Fig, 3, and finally finishing to kni-t ~he thigh part III
a,t the stitch density for the thigh 4b, In addi.tion to the stitch density adjus-tment during the above-mentioned knitting 336(~
1 process the control for insertion and removal of the yarns El and E2, ~oxward and ~ackward mo-tion and stop of sinker loop device S, and actuation and removal of the s-ta-tionary brush B is provided on the surface of the control drum D and a timing chain lO, a chain ratchet 11, a clutch drum 12, a rack wheel 5, and a belt shifting drum 13 for auto~ati.c knitting are provided on the right and lower part of the knitting machine, -thereby being controlled to make the au-tomatic kni.tting possible, The actua-ting effect introduced ~y the method of the present invention, partially referred -to in the above description of the embodiment, has b~en devised by the inventor for a long t~me, is achi~ved by a combinati.on with an inverted knitting system in formation of the tights possessing mohair tone of uni-form raised zone with not only a long pile but loops by means of completely knitting in a course direction with one knitting ~ach;ne and cannot ~e applicable to the production of the socks.
Since the above knitting process is efficiently auto-mated, this method is to ~omplete a controlling technology of a smooth change among the knitting processes for stretch 70ne~ plain kn~tted zone, and raised zone~ Furthermore, it presents, as a preferred embodiment, a method of production of the tights poss-essing the supportin~ effect ~hich mee-ts the current demand.
Due to the fact that three strands of rubber thread are inserted through the lo~er end of the part to have been first knitted, and the knitted undexwear commenced to be ~irs-t knitted fro~ the lower end thereoE, this method has a marked advantage that the knitted yarns have less opportunity -to ~ecome loose from the direction of the lower end, even when the position of each stretch is first cu-t for reconditioned utilization o:E such under-wear, ~ ~33~i~3 1 This method produces a further efEect in that it will scarcely have the knittecl yarns on the stretch zone of the knitted underwear loosened particularly to insert the rubber thread through the ~tretch zone, rrhereEore, there is an advantage of making it possible to cut the part lower -than the s-tre-tch zone for the reconditioned utilization thereof.
