Abstract
A method of knitting an upholstery fabric having at least two adjoined 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 fabric is knitted with stitches having a first loop length in one region and a second, different loop length in the adjacent region, the loop lengths of the two adjacent regions being relatively adjusted so that, in the relaxed condition of the fabric, the same number of courses in each of the two regions of different knitted structures in the wale-wise direction extend for substantially the same wale-wise distance, so as to give the overall structure a balanced even appearance.
Claims17
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, which comprises knitting said fabric on a machine having a pair of opposed independently operable needle beds, an operating cam box reciprocally movable along the needle beds and containing independently operable cam members for each direction of movement of the cam box, said members having camming surfaces independently adjustable to affect the loop length of stitches knitted on the needles operated by the cam, the needles in each bed being movable independently of one another in their beds into the path of said cam box, and in said knitting actuating the needles for one region by a cam surface of one length in the cam box so as to give stitches with a first loop length, actuating the needles for the adjacent region by a cam surface of a different length in the cam box to give a second loop length different from the first loop length, and adjusting the loop lengths of the two adjacent structures 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.
A weft knitted upholstery fabric having two regions of different structures located side-by-side in a wale-wise direction and having courses extending continuously through both regions, the loop lengths of the structure in one region being different from the loop length of the structure in the other region, thereby to balance the regions of different structure.
