The Rössolexsentörn _p iteldie, together with the sinker which they operate, carry out the threading process, are rods which extend over the length of the machine and on which thread guides, at least one for each sinker head ₉ , are arranged. The requirement is that a selected thread guide rod moves synchronously with the Rösselexzantorn hai all Vfaron widths back and forth soH _0, however, with a controlled advance of the thread guide compared to the Rössel eccentrics.

The invention is primarily intended for application to a machine with a chain the FadenführeTantrieb _B is combined with a means to obtain the required controlled advance of the yarn guide before the Rösselexzentern x-rährend each reciprocation shown below. However, it is also possible to apply the invention to a machine which is equipped with a friction thread guide drive, as will be described below.

The invention is exclusive to a raehrfonturige Flat-KulierwirJonmaschine of the specified type straightened * which is a suitable device for shaping the knitted fabric

For the following further description of the mode of operation of the assigned differential units, it is initially assumed that when the linear pen mechanism is at a standstill, the left side edge spindle 1 is only rotated by hand. As a result, the nut housing 2 is displaced axially along this worm and proportionally to the amount of axial movement _e while the link © worm 8 and thus also the worm wheel 9 of the ADU unit rotate in a sliding movement of the slide · "To effect body 11 axially along both worms 8 and 10" The consequence of this last-mentioned movement is a lateral extension of the axis of pinion 12 "in the longitudinal direction with respect to rack IS _9, which under these conditions was at a standstill so that the Pdtzel rotates about this axis _A by the bevel gear 14 to rotate. The lateral displacement of the axis of the spur gear 12 is proportional to the half of the longitudinal movement of the nut housing Z ₉ which is caused by these Drehung.der side edge "" spindle 1 by hand · upper spline shaft IB _6, the cone "wheels 19 and 20, the wool 21 and the sprockets 22 and 23 are) the two chains 58 and 74 je'um in the longitudinal direction .. the-moving "Chen amount in the respective direction _c moved to the Rösselan" drive rack 15 and to shift the thread-guide drive roll 16 »A rotation of the left side edge of the spindle 1 rotates further, and at the same time the helical gears 24 and 25 to the right spindle 26 to threaten the unit DSU, "which has the consequence _c that the Muttsrgehäuse 27 is communicated to an axial movement to top because the fixedly connected to this housing Gear 42

It is assumed that the left side edge spindle 1 is stationary and that the right side edge spindle 35 is rotated by hand. This time the right worm 10 is rotated via the chain wheels 36 and 37 _β, the lielle 38 and the chain wheels 39 and 40. As a result of this, the worm wheel 9 is turned again · = · rotates _0, however, since the latter with de? now fixed left screw engages 8 _p, the sliding body 11 of the screw S and 10 of "performs appropriate axial movement along which the Ritasei 12 and the bevel gear are rotated about their gems into ame axis 14" This axis is thus shifted laterally (because the Rack 13 is still stationary), the displacement is proportional to half the longitudinal movement of the nut housing 41, which is caused by turning the side edge spindle 35 by hand. The rotation of the pinion 12 and the bevel gear 14 causes an adjustment of the thread guide drive roller 16 and also the Rössel eccentric SC in the longitudinal direction with respect to the sinker heads - proportional to the axial displacement of the nut

By turning the right margin spindle and thus aach of the shaft 33, the spline shaft 46 is additionally rotated on the same side via the helical gears 44 and 4S. Through this caused rotation of the gear 42 about the rotating Gear 43 is again the nut housing 27 vertically upwards moved * The lever 28 is therefore again a swinging movement above to change the lever ratio of the connecting rod quadrant 34 communicated.

In other words, the adjustments for the thread guide drive tmd the fluttering, which is effected by this additional rotation of the pinion 12, are superimposed on the normal back and forth movements of chains §8 and 74 and thus combined with these. It was also mentioned that any composite displacement of the common axis of the pinion 12 and the sliding body 11 proportional to half the sum or difference

the longitudinal displacement of the side edge nut housings 2 and 41 is "This proportion is in fact the transmission ratio between the axis of the ritseis 12 and the final drive of the thread guide rods _c. Therefore, if this ratio is 4: 1" the lateral displacement of the axis of the pinion 12 1 / 8 of the assembled displacement of side rim nut housings 2 and 41,

Other more general objects of the invention are

(a) the reduction in speeds and acceleration. of to and fro masses to a minimum in order to made possible by higher machine speeds;

Cb) the creation of a higher degree of control for the thread guides, which is necessary at high machine speeds is; '

(c) the reduction of the displacement of the Rössel eccentric for each garment shape to a minimum, thus the average The speed of the machine can be increased

If the garments are to be knitted symmetrically "i.e. with the centers of their changing fabric width coinciding with the center lines of the fonts, they nut The amounts of the axial movements of the two nut housings 2 and 41 must always be the same, so that the common axis as a result of the spur gear 12 and. of the bevel gear 14 fixed remain·

The fountains of such machines are as in the one shown improved i-machine conventionally of such a width "that a front or back part is taken into account - and at The effect of a sleeve was previously less than half the width the font ineffective. It is also a fact that the time required for the manufacture of shirt sleeves is, almost as long as the one that is used to manufacture the wider back and front parts is necessary and a significant proportion of the total period between The end of one and the beginning of the next item of goods

The shaping of the sleeves, that is, the reduction and covering during the knitting work is done by conventional means _B whereby the normal main reduction devices are assigned to the Hmiptseitenrandspindeln and therefore correspond in their position for a garment part at each font and the Docker needle holder for V-shaped neckline for the second ... garment part are arranged accordingly at each fontur.
