Abstract: A machine converts a web of preformed pouches, which are defined by transverse seals extending from a remote edge, into inflated dunnage units. A sealing arrangement is positioned to provide a longitudinal seal intersecting the transverse seals to close the preformed pouches and form a dunnage unit.

Abstract: A bonding mechanism of corrugated paper making machine includes an endless loop-like band and an adjusting mechanism for adjusting position and configuration of the band with respect to a surface sheet of the corrugated paper pasted on a core sheet. The adjustment performed by the adjusting mechanism changes an area of surface contact between the band and the surface sheet of the corrugated paper and thus changing a pressurizing area between the surface sheet and the core sheet. The surface contact between the band and the surface sheet enhances bonding operation of the surface sheet to the core sheet and increases the time when a pressure is applied in the pressurizing area to bond the surface sheet and the core sheet together. The surface contact eliminates the potential damage to the surface sheet caused by application of concentrated force at a single contact point on the surface sheet and increases the manufacturing efficiency of the corrugated paper.

Abstract: The gluing together of flat materials between belt faces (21, 22), facing one another, of belt conveyors (15, 16) arranged over one another is effected usually with the application of heat and pressure. However there are pressure sensitive materials that with the gluing may only be impinged with a slight pressure. Here already the weight of the sagging belt face (21) of the upper belt conveyor may lead to an excessive pressure loading and a permanent deformation of the materials caused by way of this. The invention solves the mentioned problem in that the upper belt face (21) located above the materials to be glued is held up without contact, e.g., by means of suction nozzles or magnets. The sagging of the belt face (21) is alleviated by way of this and an undesirable high pressure loading of the materials to be glued is avoided. By way of the contactless holding-up of the belt face (21) the suction nozzles or magnets do not interfere.

Abstract: A frame, a drive mechanism for rotating a mandrel, at least two spindles mounted to the frame, a tensioner, and a belt extending between the first and second spindles may be used to roll pre-preg strips or similar sheets of composite materials around the mandrel. The belt travels over the spindles, and the spindles guide the belt through changes in its direction of travel. The mandrel is mounted in the drive mechanism in contact with the belt, which changes its direction of travel around the mandrel. The lower surface of the belt bears against upper portions of the spindles, and the mandrel contacts the upper surface of the belt. As the drive mechanism rotates the mandrel, pre-preg sheets are fed between the mandrel and the belt and are thereby wrapped around the mandrel. The belt presses the pre-preg sheets against the mandrel. The wrapped mandrel may then be removed from the apparatus and cured in any suitable manner known in the art to produce a composite tubular article.
