Abstract: In the method for cutting a continuously moving glass sheet with an inhomogeneous thickness distribution across the glass sheet, a cutting tool is moved across it at an angle to its travel direction to form a fissure and then the glass sheet is broken along the fissure. To avoid premature breakage in thin regions the applied cutting force is controlled by a controller based on control commands so that the cutting force is decreased when the glass sheet thickness decreases and is increased when it increases. In a preferred embodiment cutting force switchover points are based on an initial measurement of the thickness distribution. In another embodiment the thickness is continuously measured and the applied cutting force is automatically adjusted accordingly, so that the cutting force is greater when the thickness is greater and vice versa.

Abstract: A method and a knitting machine for producing a knitted product composed of fiber material fed by a roller pair (11c) are described. The stitches are formed as usual by knitting elements (3) being raised out of a non-knitting position into a fiber take-up position, while at the same time previously formed stitches are being knocked over, and being withdrawn again after the fiber material (6) is inserted. The presence of fiber material is monitored by means of a sensor (22), which when there is no fiber material present emits an error signal, as a result of which the knitting elements are prevented from being raised further into the fiber take-up position. According to the invention, when the error signal occurs, the knitting elements (3) are withdrawn from an intermediate position again without the previously formed stitches being knocked over and without the fiber material being taken up.
