A quilting device () comprises a processing unit () which is mounted on a frame () so as to be manually displaceable in two movement directions (MM) by an operator. A detection device () having sensors () detects the guiding force which is exerted in these movement directions (MM) by the operator. A controller device () controls or regulates, respectively, auxiliary motors () which support the guiding force, so as to depend on the detected guiding force.

Quilting device

To determine the thread supply on a lower-thread bobbin (), holes () are arranged in the shape of a spiral in a flange () of the bobbin. Light from a light source (), which is directed towards the flange (), is reflected only by those holes (), behind which there is no longer any thread, so that the light beams () reach the rear flange () and can be reflected therefrom and received by the light receiver ().
