Abstract: In connection with the unreeling of a paper or foil web from a supply reel, e.g. in a flowpacking machine, it is well known to move the web through an adjustment station for maintaining a constant tension of the web in the outer length thereof. Normally, this is achieved by the use of a synchronously driven unreeling roller partially entwined by the web and a system for adjusting the degree of entwining based on a current detection of the web tension. With the invention this is simplified by driving the unreeling roller with a peripheral speed noticeably higher than the web speed, whereby it is possible with a suitable angle of entwining to achieve both a relatively low web tension and an automatically self-adjusting, constant web tension. By virtue of the associated, rather low dynamic friction between the roller and the web, it is even possible to effectively control or maintain the lateral positioning of the web merely by the use of simple abutments for co-operation with the side edges of the web.

Abstract: The inertial drag of idler rollers in a web-offset press with independently driven drive rollers is compensated by successively advancing downstream rollers during speed changes. This prevents low-tension conditions on the web and subsequent web breaks. Compensation is made for inertial coupling to the idler rollers through the web. Tension control is utilized to stabilize web position during startups and splices.

Abstract: A yarn supply apparatus for elastic yarns in knitting machines having abruptly fluctuating yarn consumption. A yarn wheel, around which the yarn to be supplied is wrapped, furnishes the yarn to a yarn store located between a knitting station and the yarn wheel. A closed-loop controller responsive to yarn tension operates the yarn wheel via a low-inertia drive motor. The yarn store is embodied as an essentially straight segment of yarn in the yarn path in which yarn is guided so it can expand freely. The combination of a low-inertia drive motor, a yarn store that utilizes the intrinsic elasticity of the yarn, and a closed-loop controller that monitors the yarn tension by means of a sensor device makes it possible to use the yarn supply apparatus for supplying elastic yarns and to keep the yarn tension essentially constant even when the demand for yarn fluctuates abruptly.
