ULTIMA UL-269-373 – single-needle cylinder arm lockstitch machine with triple feed for medium and heavy materials

ULTIMA UL-269-373 is an industrial single-needle cylinder arm lockstitch sewing machine with triple feed, designed for sewing medium and heavy materials. Its narrow cylinder arm provides easy access to three-dimensional, closed and tubular workpieces that are difficult to handle on a conventional flat-bed sewing machine.

The machine features a triple feeding system combining bottom feed, needle feed and alternating walking feet. This system provides consistent feeding of multiple material layers, helps prevent shifting between layers and makes it easier to sew over thicker sections and uneven surfaces.

ULTIMA UL-269-373 is particularly suitable for the production of leather goods, footwear, bags, backpacks, upholstery, technical products and other three-dimensional or tubular items. The large vertical hook provides increased bobbin thread capacity, reducing the frequency of bobbin changes during production.

Its robust construction, stitch length of up to 6 mm and presser foot lift of up to 10 mm make the UL-269-373 a versatile solution for professional sewing applications requiring powerful material feeding and easy access to difficult sewing areas.
