This invention has 'fon its object to improve the construction of the knittingmachine so that this inconvenience is avoided by causing during one carriage-stroke a gradually increasing and then decreasing loop-extension foi-'obtaining a bulging in the knitted fabric and either by making the outer cams move at a certain point of the needle cylinder along a. curved gui'deso that they- 20 are shifted with regard to the cent-ral cam or by making the needle lengths decrease gradually and then increase -gradually at 'those points at vwhich a bulging produced. Three forms ot' construction are shown, 'by way ot example, in the accompanying drawing, in which Fig. 1 shows,in plan view the preferred form of construction.
hasto be Fig. 2 is a cross section on line'II-II o Fig. 1. Y Figs'. 3 and 4 show in plan view the second and third form of construction. Fig. 5 shows in`plan view a fabric knitted according to the invention.
In theFigs. 1 to 4 onl those portions of the knitting-machine are shown, which are necessary to illustrate the invention.` a are the guide-bars for the cam-box b with the cams c. dis a needle-bed.
As shown in'Fig. 1 the. two-outer cams 0 are guided by means of bolts c in slots-f of the cam-box I). 'They are secured in this position by thumb-nuts g. In each outer can 0 a linger his and rests upon a frame so that it 'can be turned in' its bearing 183,748, and-'ineermaiiy March 1'9, 1927.

In the third form ot construction shown in Fig. 3,'thc'needles, at the point in question, are of such lengths that Ithe boundary-line m along the heads of the nee- A dles is curved.-
When thecam arrives at the curve either in the guide bar 1I, the guide bars av or the boniulary-line m of the needle'heads, the outer cani c inustevidently move along these curves when the -thumb nuts loosened so that at this point a'. gradually lengthening ot' the loops will be produced, froni which results in the knitted fabric.
