Abstract: A quilting device (1) comprises a processing unit (5) which is mounted on a frame (3) so as to be manually displaceable in two movement directions (M1, M2) by an operator. A detection device (29) having sensors (27) detects the guiding force which is exerted in these movement directions (M1, M2) by the operator. A controller device (35) controls or regulates, respectively, auxiliary motors (33a, 33b) which support the guiding force, so as to depend on the detected guiding force.

Abstract: A packaging apparatus including a receptacle, a ram, a film dispensing assembly and first and second elongate members. The receptacle defines a central axis and has a dispensing end with first and second substantially linear and parallel opposed edges that define an axial limit of the dispensing end. The plastic film material forms a film tube about the receptacle. The first and second elongate members are substantially parallel with the first and second edges. In operation, the ram is extended to eject the batch of material through the dispensing end into the film tube. Retracting the ram forms a partial vacuum within the film tube between the batch of material and the ram. The first and second elongate members compressively engage the film tube between the batch of material and the dispensing end and thereby form folded flaps in the film tube. A method of packaging is also disclosed.

Abstract: To determine the thread supply on a lower-thread bobbin (17), holes (19) are arranged in the shape of a spiral in a flange (21) of the bobbin. Light from a light source (35), which is directed towards the flange (21), is reflected only by those holes (19), behind which there is no longer any thread, so that the light beams (36) reach the rear flange (22) and can be reflected therefrom and received by the light receiver (39).

Abstract: A device and method for creating sewing data using sample patterns (4) is provided in which relative movement between a detection device (27) and a sample pattern (4) is detected using an optic sensor, such as the one used in computer mice. The detection of movements is independent from any potentially visible edges. A processing unit (32) converts the movement data detected into sewing data, which can be saved in a storage unit (34, 56). Using said sewing data, a sewing machine can create sewing patterns, which are proportional to the ones of the sample pattern (4).
