If the hooking-on seems fairly secure, start the cloth in the take-up. But if it is not secure, it is well to use hand tension a little longer, since if the stitches start to break, the hand can let up quickly, whereas the take-up may pull the fabric entirely free before the tension can be released.

It is well to have the cloth in the take-up before the power is put on, since the take-up pull is much more dependable than the hand pull.

After the power is put on, watch all around the needle line for loose yam and if any appears that does not quickly knit down, stop the machine, or the needles will become clogged, in which case hooks and latches get bent, latches get bruised by the carrier and butts get cut off. Pull the loose yarn clear of the needles, taking care not to injure the latter, and hook a small piece of cloth on the bare needles and keep hand tension on it until the hole mends; or if the space is not large, take out the dial needles there, in which case the cylinder needles will generally pick up, after which the dial needles may be replaced and the rib knitting will start at once.

For multiple-feed machines the operation is substantially the same, except that each feed must be threaded just before the fabric comes to it and all of the feeds should be watched to make sure that they are clearing the stitch properly until the raw edges are down out of the way, after which there is not much danger of trouble.

RIBBER TAKE-UP

The take-up is driven by a cotton band which may be adjusted when unhooked by twisting or untwisting according as it is to be tightened or loosened.

The stop-off chain connects the take-up with the knock-off handle, and when properly adjusted releases the power if the band becomes too loose or comes off. It does not release the power if the pulley, miter gears or collars become loosened, so they should be tightened occasionally.

The sheave-wheel shaft, worm, and miter gears should be kept well oiled, but the take-up rolls should not be oiled more than is necessary or the oil will run along them upon the fabric.

The lightest tension is obtained when the weight hanger-rod is at its greatest extension back of the take-up and all the weights are on it. Moving the rod inward and removing the weights increase the tension, after which further increase is made by
