The Sailrite Ultrafeed LSZ-1 sewing machine is a straight stitch/zigzag sewing machine (Patent #6499415) featuring a mechanical walking presser foot that moves forward and back in time with the feed dog to ensure that the layers of fabric are consistently moving together through the machine. The result—heavy, bulky and even sticky fabrics like leather and window material are easily sewn with consistently symmetrical stitch lengths.
Sewn stitches can be made extra long (up to 6mm) with the variable stitch length mechanism on the Sailrite Ultrafeed LSZ-1 sewing machine. This reduces needle pucker for professional quality upholstery and canvas sewing. Zigzag stitches can be made up to 5mm wide and can be spaced tightly enough to bind edges (on a carpet for example). The LSZ-1's unusually wide 19mm zigzag walking foot creates a large, positive contact between the foot, the feed dog and the fabric itself. The Sailrite Ultrafeed LSZ-1 sewing machine walks over thick hems and makes the transition from thick to thin without skipping stitches.
Zig Zag multiple layers of materials.
High lift walking foot.
Excellent power is provided by a 110 VAC motor that develops 6600 rpm at 1.5 amps and a cogged belt and pulley drive system. In addition, a special large diameter balance wheel (the PowerPlus wheel) slows the machine down and dramatically enhances power. This wheel has been specially designed to work with our Posi-Pin clutching system. The Posi-Pin on the Sailrite Ultrafeed LSZ-1 sewing machine is a patented (#7438009) direct drive mechanism that results in 100% power transfer from the balance wheel to the machine’s needle. This novel system is much better than the typical compression clutch which is prone to slippage in heavy materials. Variable speed operation of the sewing machine is provided by an electronic foot control. This is a powerful, well designed sewing machine.
Reversing is easy with the lever activated mechanism and, because the Ultrafeed sewing machine feeds so well, back stitching for long distances is possible. A welting tunnel built into the presser foot simplifies piping installation. Ultrafeeds are great tools for building cushions which have piping trimmed edges.
A needle positioning lever allows for movement of the needle left, right and center making it possible to install most zippers without changing the presser foot. Even beginning sewers find the Ultrafeed to be a very straight forward, easy to learn machine.
Heavy duty carry case.
