ABSTRACT OF THE DISCLOSURE A method of knitting an upholstery fabric having at least two adjoined contiguous regions of different knitted structures located side-by-side in a wale-wise direction and having courses extending continuously through both regions in which the knitting is carried out on a machine having a pair of opposed independently operable needle beds and in which the needles in each bed can be moved independently of one another in that bed into the path of an operating cam box reciprocal along the needle beds and containing independently operable cam members for each direction of movement of the cam box and in which the camming surfaces of the cam members can be independently altered to affect the loop length of stitches knitted on the needles operated by the cam and in which the needles for one region are actuated by a cam surface in the cam box so as to give stitches with a first loop length and the needles for the adjacent region are operated by a cam surface in the cam box so as to give a second loop length different to the first loop length. The loop lengths of the two adjacent structures are relatively adjusted so that, in the relaxed condition of the fabric, the same number of courses of each of the two regions of different knitted structures in the wale-wise direction extend for substantially the same wale-wise distance.
