Exacta's new Formula linking machine, which has a needle stopping device, is available in two models. The Formula D model, which uses a hooked needle inside the point ring, links the garment on the right. Formula D is recommended for tubular trims. Formula R, however, uses a hooked needle outside of the point ring, and is recommended for rib times. The Formula models perform simple chainstitching and offer both continuous motion and an improved stopping device to reduce errors. Both models are designed to give operators the necessary visibility to perform functions satisfactorily. The Formula models are available with either standard or electronic motors.
