20140239530 | Extrusion Process - A method for using the quantity of heat output from an extrudate during a cooling operation in an extrusion process, wherein a fluid, in particular air, is guided along the extrudate and/or through the die counter to an extrusion direction, at least some of the heat from the extrudate and/or the die is transmitted to the fluid, the heated fluid is supplied from a first sub region of a process chain, comprising at least one die, a calibrating and cooling device and a take-off apparatus, via a connecting region, preferably consisting of at least one connecting pipe, to a second sub region of the process chain, comprising at least one suction apparatus. In the connecting region, an extraneous fluid can be added to the heated fluid in order to reduce the actual temperature of the heated fluid at least below a predetermined maximum value before said fluid is supplied to the second sub region of the process chain. | 08-28-2014 |
20130307179 | COOLING DEVICE AND COOLING METHOD FOR AN EXTRUDATE - A device for sizing and cooling an extruded flat product made of plastic material includes at least two main rolls and a polishing stack including a plurality of rolls arranged in tandem and disposed downstream of the main rolls. An adjustable sizing nip is disposed between all of the adjacent respective rolls. The sizing nip is adjustable so as to pinch the flat product during an extrusion process to a greater or a lesser extent. | 11-21-2013 |
20130236648 | DEVICE FOR GUIDING AND/OR FORMING AN EXTRUDED STRAND OF PLASTIC AND PROCESS FOR COATING A FLAT MATERIAL - A device for guiding and/or forming a plastics profile includes a region of alterable cross-section formed by a wound flat element. The wound flat element overlaps in a region and is in close mutual contact in the overlapping region. The wound flat element includes a flexible and resiliently deformable coating thereon. A device is provided for altering the region of alterable cross-section. | 09-12-2013 |
20120273992 | DEVICE FOR SEALING A COOLING TANK FOR AN EXTRUDED PLASTIC PROFILE - A device for sealing an extruded plastics material profile in at least one of an inlet region and an outlet region of a tank is disposed at an end face of the tank. The device includes a rigid element and a closed annular cross section formed of a resilient material and including a cavity. An outer peripheral shape of the annular cross section is disposed against the rigid element. The annular cross section is alterable by applying a vacuum to the cavity, wherein the annular cross section is configured to be applied to an outside of the plastics material profile. A stretching device is disposed against the rigid element and is configured to stretch the resilient material along an extrusion axis during an alteration of the annular cross section. | 11-01-2012 |
20120205831 | DEVICE AND METHOD FOR COOLING PLASTIC PROFILES - An extrusion line for producing plastics material profiles includes an extruder, a calibration station, and an additional piece of downstream equipment. A mold includes an internal cooling system having a branch for a coolant disposed inside the mold; wherein a coolant flow distribution is controllable. | 08-16-2012 |
