A fabric made according to the foregoing explanations would be what is known as a jersey fabric (see Figs. 12 and 13), but it would be a flat piece of fabric when finished. Perhaps to make it plainer I should say that if the fabric were laid out on a table it would be a single thickness, and if it were to be made into a garment it would be necessary to double it over and sew the edges together to make it tubular, or in the form of a bag. If we wish to make the fabric tubular on the machine to save the labor of seaming it, and also prevent the unsightly seam, it would be necessary to use the needles in both plates, front and back. The cams would then be set by means provided, which will be explained later, so that when the carriage is moved in one direction, say from left to right, the front cams will operate the front needles and the back cams will be put out of operation; and when the carriage is moved from right to left, the back cams will operate the back needles and the front cams will be put out of work.
