Abstract: Slitting shears comprising two knife shafts which are adjustable in relation to one another and are equipped with at least one knife each are described. Some of the knives are adjustable by means of compression springs and with compressed air in the opposite direction in parallel to the axis of the knife shaft. By correspondingly selecting the tensioning force, a machine tool is created which makes possible the automatic adjustment of the tools, especially knives and spring-loaded knives. Besides the reliable contact of the pairs of knives which is achieved as a result, the machine is made ready for operation in a simpler manner and more rapidly, especially in the case of a tool change.

Abstract: The present invention pertains to a floor-type cluster mill with a set of rolls above the nip and a corresponding set of rolls under the nip, and preferably with direct hydraulic adjusting means. The cluster mill is characterized by the possibility of conversion between a 14-roll mill and a 20-roll mill, wherein each set of rolls has, in both cases, a number of rolls that are to be maintained unchanged and a number of rolls that are to be replaced.

Abstract: A process for the removal of films of flow agent from moving strip material, by squeezing away the film by means of squeeze rollers and an air flow duct which each extend transversely with respect to the forward feed direction of the strip material. The air flow is directed along the squeezed-away cushion of flow agent, and entrains the cushion of flow agent. Apparatus which is used in the process includes air flow ducts which extend transversely with respect to the forward feed direction of the strip material, and which are positioned at the point of entry of the strip material into the squeeze region.
