UAB Siuvimo manija is the official distributor of JACK sewing machines in Lithuania.

Built-in servo motor
The motor is fitted inside the machine housing. It lets you set the required speed and position the needle – it always stops in the upper or lower position, as you choose.
The motor runs only when the pedal is pressed, so the machine works very quietly. There is no belt, which in older machines linked the shaft to a motor mounted under the table, so there is no vibration either. Compared with clutch motors, the machine starts sewing smoothly, without a jerk, which makes complex parts easier to sew. Electricity consumption is up to 80 % lower.
Thanks to low noise and vibration, the machine is suitable for people working at home or in premises with noise level requirements.
Reliability
Machines in this series run smoothly and quietly, have a modern design and an improved lubrication system, and are well assembled.
