摘要： A method and system for processing a heated flexible sheet, with oppositely facing surfaces, that is advanced in a processing path. A first cooling roll has a first peripheral surface for contacting one of the sheet surfaces. A second cooling roll has a second peripheral surface for contacting the other sheet surface. The system is configured so that the first and second cooling rolls are selectively movable in relationship to each other in a manner, other than by moving one or both of the first and second cooling rolls towards or away from the flexible sheet, between: a) a first relationship wherein the first sheet surface is caused to engage the first peripheral surface over a first circumferential extent as the flexible sheet is advanced in the processing path; and b) a second relationship wherein the first sheet surface is caused to engage the first peripheral surface over a second circumferential extent that is different than the first circumferential extent as the flexible sheet is advanced in the processing path.

摘要： An air ring has a main body including a plenum through which pressurized air enters the air ring, the main body including a generally circular interior that is unobstructed vertically above the main body. A generally circular forming-cone assembly is received in the generally circular interior of the main body, and includes at least one annular lip defining a passage through which pressurized air from the plenum exits the air ring for impingement upon the polymer tube. A plurality of fasteners secure the forming-cone assembly in the interior of the main body, the fasteners and forming-cone assembly being unobstructed vertically above the air ring, wherein the fasteners are accessible from vertically above the air ring and the forming-cone assembly is removable from the main body by vertical lifting without removal of other components from the air ring.

摘要： A method for forming a multilayer plastic sheet material is disclosed, where a first polymer mass is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed. This is passed to two or more rolls of a finishing stand that processes the multilayer plastic strand into a sheet. After the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand. The speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that the plastic strand is processed without stress.

摘要： A blown film line and process for making blown film, including an annular extrusion or coextrusion die, a plurality of nip rollers at a location remote from the annular die, a blown film bubble extruding from the annular die and traveling toward the nip rollers along a traveling path, an air cooling apparatus in the vicinity of the annular die, and a water cooling apparatus located downstream from the air cooling apparatus along the traveling path. The water cooling apparatus includes a wet porous material in direct contact with the blown film bubble and surrounding an outer circumference of the blown film bubble. The wet porous material continuously wipes the blown film bubble with water as the blown film bubble moves along the traveling path.
