Abstract: A method and mechanism for dewatering a web in a paper making machine having press means, a first thermal dryer section having a long continuous support looped belt carrying the web along a first drying run with rolls and suction zones beneath the web and a hot air generating means for directing a flow of air onto the web in the first thermal run with the web being received substantially 40% bone dry at the beginning of the first thermal run and being delivered substantially 50% bone dry at the end of the run onto a heated drum dryer section.

Abstract: An oven for heating tubular parisons to a target or orientation temperature. A first plenum on one side of the oven and a second plenum on the opposite side of the oven, both exhaust to a common chamber disposed therebetween. The parisons are heated by a high velocity fluid above the target temperature in the zone defined by the first plenum and the chamber and the parisons are tempered by a lower velocity fluid at the target temperature in the zone defined by the second plenum and the chamber.

Abstract: An oven for uniformly heating parisons to a target temperature, including a movable wall portion which is raised and lowered to accommodate parisons of various axial lengths. The movable portion maintains a confined flow path to minimize stray air currents.
