With reierence to the drawing, the kno wn pressing process will first he briefly descri (it: After the frame needles i hove been provided with threads, the needle ber t will move down and, simultaneously, towards the sinker head i to such an extent that the elostic hooks of the frame needles i are closed on the presser edge let the sinker heed t. Thus the loops 5 on the irsme needles 2 will slide onto the hooks thereof and be thrown off during ier descent oi the needles 2. e newly iormed loop handles i posttioned under the hooirs oi the irome needles i are then drown through the old loops t and made into new loops. I

l ies. i ondt show how the presser process is esrried out by moons oi the norrovrinc and presser mecsm cocci-dine to the invention. As indieoted in i, the ironic needle i moves down in the must only, with the difference, however, as compared with the previously described process that in order not to engage the normal presser mechanism it does not descend to the presser edge t oi the sinher head 5 but remains at a certain distance from the edge. Siomrlteneonsly with the ireme needle i, the covering needle l moves down until its deflection B m as o presser surface is on olevel with the presser edge i of the sinker head i and in front of the heel: oi the ironic needle 2 which places itself against this deflection. h of the needle l in such o, way thot the oil: is closed. Onlythe tree needle hook is closed, however, opposite to which or covering needle l with o deflection if'is positioned while all other irome needles remoin open end the loops locnwd on. these open needles ere there.- iore not thrown off.

The presser ps occordinr to Fig. 2 diiiers from the process jmt described only in so for its the closingoi the heel: of the frame needle takes piece the shove the or throet, so thot timing the descent oi the is needle the newly formed loop hendie is flooded on the closed: hook oi the frame needle end, during iurther descent of the letter, thrown oil.

The coves not end. prerser points shown in 3 to I convey on ides oi the merry rises oi the device according to the invention. Fin. 3

shows o covering needle i possession is presser tones wed in such o trey that, so demrihed tlli Kid

already with respect to Figs. 1 and 2, within one downward motion of the frame needle 2 the covering needle 1 having a higher presser surface 8 will close the corresponding needle hook above the sinker throat while the covering needle with lower presser surface will close the corresponding hook above the knocking over bits and therefore at normal pressing height.

Furthermore, according to Figs. 5, 6 and 7, needles I may be used which are constructed solely as presser point and not as covering needles. The various kinds of needles may be disposed in any grouping in one and the same bar or in a plurality thereof which act jointly or individually and independently of one another. Moreover, in addition to covering needles having a presser surface, covering needles without presser surfaces may be employed to provide a great variety of combinations to take care of many different purposes.

indicated by the description of Figs. 6 and 7, the presser surface formed by the deflection l of the covering needles may be replaced by special parts. In the construction shown in Fig. 6 the narrower i ll carrying the covering needle 1 supports a screwed-on comblilre plate 217 whose prongs 28 extend into the elevations ll serving as presser surfaces. In Fig. 7, the comblike presser plate or the like is secured by a special holder 3d to the rotatable rod it which can be laterally displaced independently of the narrower, so that it is possible to render the presser bar operative or inoperative, according to requirements.

The invention may further be applied to jacquard lace full-fashioned flat hosiery machines by causing the covering needles provided with presser surfaces, during the presser as well nan'owing steps, to be brought by the jacquard attachment within or out of range of the frame needle hooks, so that these attaclnnents can be used also for working jacquard tuck patterns and the like besides serving their main purpose of producing jacquard lace patterns.

For carrying out the process described above the narrowing mechanism found in every flat hosiery frame is used after being suitably changed or supplemented, as shown in Fig. 8. V

In the hosiery frame according to Fig. 8, 9 is the machine frame in which the shaft i3 is rotatably disposed and carries the arms i l supporting on their front end the shaft to. The shaft l is provided with the holders it in the guide of which the bars ill and iii are displaceably disposed with the narrowers iii. The frame 9 further carries the bolts til to which the levers M are secured and provided with rotatable rolls 22 which rest on the cam M disposed on the main shaft 23 and which, by means of the connecting rods 25, carry the narrowing machine or determine the height of the narrowers l9. Below the rear ends of the levers 2B the supports 26 oscillatorily secured to the frame 9 are provided on which the levers 2| may rest as long as the supports 26 are within their range, i. e., as long as the narrowing machine is not moving up and down but inoperative.- However, if the narrowing machine is to be lowered for patterning, narrowing, widening or, according to the invention, for carrying out the presser process described, the supports 26 will be moved out of range of the levers 2| into the position indicated by dots and the narrowing machine can then move according to the form and rotation of the cams 24. For the presser process, the cams 24 are fitted with an inward bulge 32 to insure lowering of the narrowing machine after the motion of the supports 26 at the time when the frame needles 2 are lowered also. For narrowing, however, the standard narrowing cams, not shown, are provided which act in known manner by the lateral displacement of the main shaft 23.

As soon as the supports 26 are moved out of range of the levers 2 l, the rolls l2 will be laterally displaced so as to engage the cams ll havinga low presser point and to bring about the descent of the frame needles 2 at the requisite distance from the presser edge l of the sinker head 3.

The device according to the invention is particularly suited for producing hosiery with widened heel portions whose leg and foot portions are made without interruption on one and the same machine, though it can be profitably used also for making tuck pattern goods, such as twill, or for working in run stops, ladder-proof initial courses and the like.

I claim:--

1. In a fiat hosiery frame a narrowing mechanism for transferring loops and acting as auxiliary presser mechanism during looping, a grooved covering needle, a frame needle and a presser surface arranged above the groove of the covering needle and projecting from the plane of the latter to close the hook of the frame needle.

2. A flat hosiery frame according to claim 1, comprising a presser surface forming part of the covering needle.

3. A flat hosiery frame according to claim 1, comprising a presser surface consisting of a de ilection of the covering needle.

4. A fiat hosiery frame according to claim 1, comprising presser means arranged on the narrowing mechanism in front of the covering needle and carrying the presser surface.

5. A flat hosiery frame according to claim 1, comprising a cam having an inward bulge to perunit lowering of the narrowing mechanism during looping.

6. A flat hosiery frame according to claim 1, comprising supports movably disposed in the frame for holding the narrowing mechanism in inoperative position during looping.
