catch channel 27 and the drain lines 30 connected thereto but should flow away rapidly enough in the direction of the collecting container 29 the depth and the width of the catch channel 27 and the crosssection of the drain lines 30 therefore also depend on the kind in particular the viscosity of the lubricant employed and have to be determined by experiment in each particular case initial experiments on circular border knitting machines with a diameter of 30 34 have shown that a depth of about 3 mm should be selected when using an ordinary lubricant and the width of the catch channel 27 should also amount to about 3 mm at least at its widest point i e in the upper region just below the knitting implements 14 for preference the cross section of the drain lines 30 should thus also be chosen correspondingly in order that lubricant drops 35 introduced to the catch channel 27 shall not be thrown out again radially from the catch channel 27 by the centrifugal forces but shall flow safely into the drain line 30 and thence into the collecting container 29 the catch channel 27 is bounded at the radially outer edge of the dial 2 by a wall 36 fig2 which makes a predetermined minimum angle u03b1 with a plane perpendicular to the conceptual axis of rotation of the dial 2 and of the needle cylinder 1 shown by a line 37 and running parallel to the bottoms of the tricks 25 the radially inner wall of the catch channel 27 opposite the wall 36 is disposed vertically for example so that its angle of.
