Device: one or more systems. Ii _; en, · in particular single-cylinder dog knitting machine

The invention "relates to a device of a single or multi-system, in particular a single-cylinder circular knitting machine Manufacture of fine, seamless women's stockings and the like, in which each knitting system with an axially movable cam or trigger cam part sur actuation of jtfadelfÜisen is wrong, which advantageous isur adjustment of the density in the individual ibaschenreilien the knitted fabric is used.

It is known that with one person only in a run on one Circular knitting machine knitted stocking the heel by forming larger stitches, e.g. 3. in every second row, preform, but the heel bulge thus formed in this known stocking lacks the characteristic of the continuous one Change of the loop size.

It is also known that the Laec-ien ix. lert-er: - or tip part cle & ο trumps in the direction of the rows of flaps in size and then decreasing again to work to form a dome-shaped bulge with gradual over ^ on,;, "to the adjoining üor ^ alf.e & trick. The device used for this purpose is designed so that a gradually rising and then gradually falling in the direction of the Uafange of a ifockentromrnel rotating synchronously with the 1, 'needle cylinder to control the depth of one or more cam or trigger lock parts also in the direction of the iTo-L -unelaehse shows a ... gradual increase or decrease, for this purpose the movement of the roller on two-armed roller levers to the control of the individual locking or removal lock parts with the same angle parts are necessary to reduce the movement. ^r oclcentromnel like the Kulier- or Ab ζ U £, s closed parts arranged around the needle cylinder.

The listed devices have the xth disadvantage, that they are relatively complicated and demanding regarding their attitude. In addition, they take up an essential space in the immediate vicinity lieh of the Iladel cylinder, what in particular disadvantageous for circular knitting machines that are more difficult to use is.
