Circular knitting machine with electromagnetic-mechanical control of the knitting needles.

The invention relates to a circular knitting machine with electromagnetic-mechanical control of the knitting needles, in which the cylinder and / or liippnadeln can be selected by the pusher upstream of the hadles and the pusher by Tedex-nde rods by the resilient rods at each knitting point by control magnets from their effective Position or swiveled into its effective position. Such a device is known from JiM patent specification 39-730.

The invention is based on the task of ensuring that there is sufficient distance between the resilient rods, particularly in the case of fine filings. This object is achieved in that a, .nkor is provided on each resilient rod, the size of which is larger than the size of the rod, that in the circumferential direction of the iodolz, 7lindors adjacent anchors are arranged in different itohon levels and at each * selection 3 .olio a number of üoeroinundorliogonden ,, beuerraagnotes provided ir.t. corresponding to the number of liöhön levels. /οχ·/,ιι.";πν/θΧ3θ rjiad while the hooks of the resilient .AsKuaiiCsn iiaaen on the ΐ.ηΚ ': £ Ί ·, .ι'ιβ ijikev eier forwarding Sfcübclion are on "' joi or in dependence; -; ability; from the toiiung to even more jjvf-'i ^ onuilen., puren ι .in the needle cylinder, and ^, was behind-

alternately in the different tracks. According to the particularly preferred embodiment, about each Feather rod pushed an anchor, which has a nose, the ge according to the height of the left is located, can engage in a recess provided in the pusher at a corresponding height. Using resilient rods of the same length are also arranged at different relative heights, whereby for all Spring sticks of the same height control cams provided are. The pushers have two or more locking cams, which are at the same distance as the control magnets are arranged one below the other and in which the xiaken of the spring rods snap into place,

Since the spring bars must have a certain width if the control magnets are to work properly, but with fine 'filings this leads to difficulties leads, they are provided according to the invention with an anchor, which, however, the entire for a spring rod available width in the needle cylinder is determined by the width of the anchor, which is much greater than the width of the feather stick, pestle or knitting needles can be. This would still limit the division of the circular knitting machines

By the inventive arrangement of the ^ nker the u'ederstübchen at different heights each anchor is to both sides my ¹ xiaum available, so that neither the division by the required I4iiidestbreite of the armature or the maximum jJroitG of the armature by the desired i \. - limited iat.

is enlarged. The formation or arrangement of the control magnets in different tracks and the associated ones However, advantages of increased operational reliability are not the subject of the invention, since the selection of the Knitting needles by a number of control magnets arranged one above the other already from the Swiss ratentschrift 362 787 is known.

The control magnet can be in a known manner Permanent magnet are connected upstream to which the spring bar is brought up by means of a fixed curve and moved via the control magnet as it continues to move, who holds or lets go of him according to the pattern. The control magnet can be followed by a permanent magnet, which the The spring bar held in place by the control magnet is secure brings up behind the selection point. Similar useful control magnet designs are the subject of an older one Suggestion. With this type of construction it is sufficient if the handle division is changed, close the! magnetic cylinder change · The spring bars are arranged outside of the pusher channels so that their cross-section differs from the pusher width is independent. The anchor attached to the spring rod preferably has at the same time on its inner edge the iM'ase with which the pusher prevents unwanted movement is locked upwards. Length and cross-section ratios of the spring rod and the magnetic iron used for the armature can remove the magnetic Requirements can be adjusted without spatial hindrance.

In the drawing is an embodiment of the invention shown. Show it:

In the Nadelylinder.- 1, the pushers 3 are in the channels 2 stored lower part of the needle cylinder. The knitting needles are not shown above the pusher. Each pusher is assigned a spring 4 - 4 in a recess 1a of the needle cylinder, the associated spring Pushes pusher up. A fixed curve 5 ensures that all pushers in front of the selection point are brought to their lowest position according to FIG. 2, where they are by the hook 6a on the spring rod 6 at the end of the curve 5 are prevented from moving upwards or when the spring rods are pivoted outwards (on the left in FIG. 2) at the end the curve 5 pushed up by the spring 4 and by the thrust of the spring or a non-illustrated fixed expulsion curve of the associated needle issue an upward movement. The pen sticks 6 are As FIG. 1 shows, in two different heights by the upper fastening means 7 ° and the lower fastening means 7u is firmly connected to the needle cylinder at its lower end. An anchor 6b is attached to each spring bar; the upper spring sticks are marked with 6o and the lower spring sticks with 6u. In the area of the anchor 6b of the upper spring rods 6o is the upper magnet 8o and in the area of the armature 6b the lower spring rods 6u the lower magnet 8u, so that the spring bars are influenced alternately by the upper and lower magnets 8 will. At each selection point, three or more control magnets can also be arranged one above the other, from each of which controls every third etc. feather stick. In these cases, the anchors of the spring sticks are on three or more horizontal tracks.
