Uses of Flat Knitting Machines:
Articles knitted on flat machines range from trimmings, edgings and collars to garment panels and integrally knitted garments. The common products: jumpers, pullovers, cardigans, dresses, suits, trouser suits, hats, scarves, accessories, ribs for straight-bar machines (fully fashioned machines).
