' 21,2'16/61; Dec. 28; 1961, 23,434/61 9 Claims. (Cl'. 66-134) This invention relates-to a yarn end cutter for circular knitting machines for cutting off' the loose yarn ends which womens stockings made on circular knitting machines exhibit in the lateral reinforcing zo'ne.
It is known that, during a reinforcing process in which reinforcement are provided on the heel and on the insole of womens stockings, there remain, in the peripheral zones of said reinforcements, loose yarn ends, and, to be precise; one end for each stitch relating to the reinforcement, commonly" called beards; which must obviousl'y' be sheared off as closely as possible to the terminal stitches of the reinforcement. v
For'thisparticular' operation several devices are'known, and they can be divided substantially into two groups, namely: a first group consisting of apparatuses which act directly on the stocking during its making, that is to say duping the making oflthe' aforesaid reinforcement, and a second group of devices for shaving the beards on al ready manufactured stockings, which devices are manually operated by suitable personnel.
The apparatuses of the the first group are generally of the type with electric resistances, rollers, s aw-blades or scissors, but these apparatuses leave too long beards and the stockings produced thereby are considered of poor quality; the same electrical resistance deviceswhich have been more recently adopted cut off the thread at a relatively large distance from the end of the stitch, which they are compelled to do by the safety margin required to avoid damaging the rest of" the stocking being'rnan u factured; furthermore, said electrical resistance appraratusesdo not allow a high spe d of rotation of the needle drum, and hence their adoption adversely affects the costs of productionof the stockings;
With regard to the devices of the second grou -i.e., those manually operated; these devices are costly because they involve an extra operation after the knitting of the stocking, and lead to a certain number of discards as a result of the products being damaged, piece-work being generally employed for such operations.
This invention, in order to overcome the drawbacks described, proposes a system of specially shaped knives endowed with a relative back-and-forth motion which enables threads to be cut regardless of the direction of movement of the knives, the thread to be introduced between the cutting edges during each stage of the reciprocal shifting thereof, which results in [a very high rate of production. In particular, use is made of two knives, each providedwith two cutting edges, which knives are set inreciprocal motion by a high firequency vibrator actuated, for example, electromagnetically or pneumaticly or by like means;.thev preferred vibration frequencies range from 33 to 100 periods per second and, particularly with electromagnetic, alternating current vibrators, in dustrial frequencies are employed, i.e., 50 or 60- cycles per second.
This invention also provides for a device for the introduction and withdrawal of the knives provided with cutting edges into and from a space above the needle drum, by means of a slide actuated by a mechanical system, such as, for example, a flexible cable controlled by a cam provided on the drum which controls the several Patented Apr. 19, 1966 stages of stocking-making of the circular machine,- which cable acts in opposition to a; spring" which always acts in the sense of withdraw-ingthe slide and its knives-from the inside of ne'e'dle drum; this has been provided with the object of preventing any'b-reaka'ge or damage of the cable actuating the slide or from causing damage to the rotating needles; It should be noted' that the knife device according to" this invention cuts on the thread is kept stretched and brought to the inlet or the cutting edges by a serrated ring" norm 1 y provided on the platen immediatelyabo've the-ring/ofi aliitens and hence at a practically negligible distance 1" the end p'artof the: stiteh; -for this pu-rpose specially s aped tops of platens; with lowered heads, can be designed Eachof thecfutt in'g is provided with a? v shaped notch forming on each: kn e a pair of cutting ed es ex: tending transverse to the elongation of the knife;-

- On a: circular two feed knittingmachine provided with continuous motionrfor the formation of tubular stockings for Women (see FIG. 1 there is fitted; by means of a projecting; arm 1: fixedto the frame; the cutting device indicated as a whole by the numeral 2 and described in detail hereinafter; said device being situated in one of the two zones in which the needles are lowered; sc -that the system of cutting knives: is at a tangent to thec'rown ofthe sinkers: which are provided for forming-the reinforcement', e.g.,-the heel-1 and theinsole'ofthe stocking The cutting device: according; to this invention is' composed ofi a slide 3- provided with a dovetailed guide 4 which slides on a support 5 forming a single piece with; or being attached to the: projecting. arm 1' which is fendered integral with the frame-.-
The slide3 is actuatedby means of a: flexible cable 6 the sheath of which isfastened in: an adjustable-manner known in itself against a support 7 integral withthe frame. 7
said cable 6 isactuated, in known and conventional manner, bya cam (not shown in tliedrawing) appropriatelypro'vided oni the drumlwhich'controls the various stages of the'working'of the'macliine, the cable acts in the direction of arrow A to push the slide" towards the working positionof the lowered needles 9:, indicated" by the numeral 8 in-FIG 1i The arm 1 and-guide Sfi'xed thereto form a first' support fixed 'to*tlie knitting machine and'the slide 3 forms a' second suppor-t which isrnovably p'efi head;- illustrating the mounted between a working position and an inactive position on the first support.
The slide 3 carries at its top an assembly formed of two knives, 11 and 10 respectively, overlapping each other, the lower one being fixed and the upper one actuated in opposition to a spring 12 by self-contained oscillating means, for example, an electromagnetic vibrator 13 of known construction as for instance shown in the U.S. Patent 2,895,064 which acts so as to attract knife 11; it is manifest that the vibrator will be attached to the assembly of slide 3 and lower knife 10 with its support frame. It should be noted that the movement of slide 3 relative to support caused by cable 6, takes place in opposition to a spring 15 which is attached respectively at 3 and 5, and which is biased so as to tend to move the slide-knives-vibrator assembly in a direction away from the crown of needles.
Thetwo knives and 11 carry laterally at their ends notches 20 and 21 of different shape and such that, when superimposed in any reciprocal positions, the lateral faces always present an aperture for the thread which is brought to it by any means, e.g., by the notched ring 24 forming part of a dial plate provided in this type of machine. The two notches 20 and 21 provided with cutting edges on both sides of the slits, are of different shapes, indicated exactly in FIGURES 4 and 5 on an enlarged scale for the sake of greater clarity, and, to be more precise, both have a V shape, notch 20 being wider than notch 21.
Substantially, the working of the device is as follows: during the normal formation of the reinforcement, the drum controlling the various stages of the process of the machine, causes, by means of a cam, not indicated in the drawings, a pull to be exerted on flexible cable 6 which moves slide 3 and the assembly of knives 10 and 11 and the vibrator 13 towards the crown of needles in the zone where the needles are lowered 8; at the same time the drum itself can actuate a switch which operates the vibrator 13 (e.g., alternating current, electromagnetic vibrator running at 60 cycles per second) which, in opposition to'spring 12, moves knife 10 back and forth relative to the fixed knife 11 which is almost tangential to the crown of needles: the thread, entrained by the notched ring 24, is introduced into the aperture which is always present between the notches 20 and 21 and is then cut off by the cutting edges. When the reinforcement has been finished, the same cam on the control drum will release cable 6 and spring 'will restore the knives and the slide 3 to the rest or inactive position automatically, while the same switch as hereinabove referred to but not illustrated, can interrupt the supply of current to the Vibrator.
With the sofar described arrangement, the thread to be cut off is kept stretched in a strongly inclined position (as shown in FIG. 8) towards the plane of rotation of the needles. In this manner it is manifest that the knives cut off the thread at a certain distance from the last needle of the knit being rotated. This is, obviously, a drawback, and to overcome it the arrangement of FIG. 9 is proposed.
In FIG. 7 are indicated three positions a, b and c in which a represents the intermediate position, b the position in which the upper knife 10 is at the end of its inward travel, and cthe position in which the upper knife 10 is at the end of its outward stroke.
It should be noted that in the relative. movement between the two knives, the thread is obliged to pass along a distance S, and that during this time of passing along said distance, the upper knife executes at least two cutting movements.
I In FIGS. 8a and 8b the numeral 101 indicates one hook of the normal type of a plurality of hooks carried by the dial plate, which remains in a zone near to a thread 102 which has to be cut off and which is stretched between threadguide 103 and the head 104 of a needle relating to the knit that has been made.
Since the plurality of needles 104, 104a, 104b, etc. is rotating at high speed, the cutting of thread 102 by knives 10 and 11 can take place only at a point d which is at some distance from the head of needle 104, the angle a formed by said thread 102 and the plane of rotation of the needles is rather small.
In order to obtain a more effective cutting, i.e., a reduction in the distance of point a" from the top of needle 104 (FIGS. 9a and 9b), it is necessary to provide the device with means suitable for dragging the thread 102' in synchronism with needles 104', 104a, etc.; for this purpose there are provided noses 105 on each hook 101 of the dial plate 24 so that the thread 102' hooked by corresponding nose 105a placed in rotation with the platen assembly is obliged to follow a broken line between the head of needle 104 and a thread guide 103. The hooks 101' with the noses 105 thereon constitute therefor means on the dial plate for hooking and deflecting the yarn as it passes from the thread guide 103 to the respective needle. In this manner the thread, leaving the plane of the needles, remains stretched at an angle rang-ing between 75 and relative to said plane of rotation.
In this manner the knives will cut the thread while it is arranged almost perpendicularly to the plane of rotation of the needles. It should be noted that the thread can be carried between the noses of the platen hooks by means of known devices and, in particular, by the thread-guides themselves suitably rotated with a small lifting movement caused, for example, mechanically by means of cams according to a known motion already employed for other processes.
