The DL device can be used to instantaneously maximize the alternate vertical movement amount. This device is useful,
in particular, in processes for sewing products with many multi-layered parts.
The machine is provided with both hand switch and knee switch.
The bobbin thread remaining-amount detecting device warns the operator with a buzzing sound and lamp indication
of the time for bobbin thread replacement. This allows the operator to concentrate on sewing work without concern
for the remaining amount of bobbin thread.
Since the device directly detects the bobbin thread amount remaining, cumbersome setting is no longer required
regardless of the material, thread and process.
