Title: Plough folding device for the longitudinal folding of a web of material
IPC: B41F13/58
Filed: 1988-02-26
Granted: 1989-06-01
Abstract: In a device for the longitudinal folding of a web, a plough folding head which is infinitely variably adjustable in its working width is arranged with a suspension which is displaceable transversely to the running direction of the web. The fold line and the working width of the plough folding head, thus also the distance between two folds in the case of double gate folding, can be controlled via two adjusting mechanisms driven by servo elements, position transmitters providing signals via the adjustment coordinate values. The control of the adjustment of the plough folding head transversely to the running direction of the web is supplemented by control of the adjustment of the layout angle which is essential for plough folding, in that the distances between the inlet roller, outlet roller and plough folding head are adjustable. The data of the positions set can, on the one hand, be controlled in the process and, on the other hand, can be stored for presetting purposes. To improve the fold edge formation, a closing device which can be incorporated in the adjustment is arranged upstream of the outlet roller. The adjustment intervention possibilities, especially in relation to the plough folding head which can be made narrower or wider without gaps, can also be used to guide the fold register. All the adjusting mechanisms can be used in overshot and undershot working positions of the plough folding device.

Abstract: Device for packaging a stack of paper, comprising a folding-box unit (1) and a suction-rod unit (2). The folding-box unit has a plane for receiving a packaging blank and a stack of paper pushed thereon, and tool elements (4) for erecting the side parts of the packaging blank to form a half-box. The suction-rod unit consists of a plurality of suction rods (8) which can be moved up and down simultaneously and whose heads form the receiving plane. The packaging blank, together with the stack of paper, can be lowered through the folding-box unit with the aid of the suction rods, during which operation the side parts of the packaging blank are erected on the tool elements. The folding-box unit has a plurality of folding-box guide bars (9, 10) which cross one another at right angles and by means of which or on which the tool elements can be altered with the aid of actuators for the purpose of format adjustment. The suction-rod unit possesses suction-rod guide bars (13, 14) which are parallel to the folding-box guide bars and with which the suction rods are connected by means of holding devices and with which and also on which the suction rods are displaceable for format adjustment. The suction-rod guide bars are connected mechanically to the folding-box guide bars and can be moved together with these.

Title: Process for selectively removing non-volatile substances from non-alcoholic or alcoholic beverage or sugar-containing solution
Inventor: VALTER GRESH
IPC: C13B20/16
Filed: 1989-04-26
Granted: 1995-10-20
Abstract: FIELD: non-alcoholic or alcoholic beverage industry. SUBSTANCE: the process for selectively removing non-volatile substances from a non-alcoholic or alcoholic beverage or a sugar-containing solution comprises stepwise diaphragm separation by ultrafiltration and reverse osmosis into a permeate and retentate, removal of non-volatile substances such as sugar and/or acid, and/or an unpleasant-smelling substance, or conversion and use thereof in the final product, and the non-volatile substances are removed or converted from the retentate by using physical or chemical or biotechnological processes suitable for the separation of non-volatile substances, and the substances that remain after removal or conversion are at least partially once again subjected to conversion or become part of the final product. After removal and conversion of the substance, the permeate is at least partially returned to the retentate after diaphragm separation or to the recycled permeate which mounts a device for removal or conversion of a substance. The sugar that is contained in the permeate or retentate is converted by fermentation to an alcohol which is at least partially removed, and the permeate containing aromatic substances is once again added to the retentate or permeate. If ultrafiltration is employed, the separation boundary is 5000 Dalton, at maximum. When diaphragm separation is employed, the diaphragm is selected in such a manner that the permeate contains substances that should desirably be present in the final product, and the retentate contains substances to be removed or converted. Prior to stepwise drophragm separation, the beverage or solution is preliminarily separated according to a diaphragm separation procedure, and the resulting retentate is added to the retentate when diaphragm separation is employed, and the permeate is added afterwards. The preliminary separation boundary is below the diaphragm separation boundary and selected so that said boundary separation is within the reverse osmosis and ultrafiltration and boundary zone. This boundary is within the boundary zone of reverse osmosis and ultrafiltration. EFFECT: more efficient selective process. 17 cl, 3 dwg
