Publication number: 20170312966Abstract: The smoothing device for plastic films comprises plastic-melt-producing means (1, 5), an adjustable slit die (10) and a roller smoothing unit (16) having cooled smoothing rollers (11, 12), which form an adjustable smoothing gap (13) between each other. Optionally, further rollers (15) are arranged downstream. A thickness gauge (23) measures the thickness of the plastic-film web (22). A controller (30) for controlling the thickness of the plastic-film web (22) may set a setpoint thickness (SD) of the plastic-film web (22) and the volumetric flow rate (SS) of the plastic melt or the line speed (LS). The controller (30) captures the current torques and rotational speeds of the rollers (11, 12, 15) and the current thickness (FD, FD1-FDn) of the plastic-film web (22).Type: ApplicationFiled: November 2, 2015Publication date: November 2, 2017Inventors: Jürgen HAINDL, Harald HÖLLER, Markus FELLINGER

Patent number: 8088885Abstract: An installation for increasing the intrinsic viscosity of a polyester material by solid phase polycondensation (SSP) comprises a heatable reaction container (2, 2?) in which the polyester material (P) can be left to reside at a predetermined thermal treatment temperature for a predetermined residence time until it has reached a desired intrinsic viscosity, and a cooling container (6, 6?) arranged downstream of the reaction container, the cooling container (6, 6?) being designed for cooling the polyester material discharged from the reaction container to a first cooling temperature which is lower than the reaction temperature. Downstream of the cooling container (6, 6?), a polyester material separator (7) is arranged which is designed for diverting the polyester material flow to a polyester material processing machine (8) and/or to an intermediate storage container (10).Type: GrantFiled: June 13, 2006Date of Patent: January 3, 2012Inventor: Markus Fellinger

Patent number: 7358328Abstract: The invention relates to a process and a device for increasing the intrinsic viscosity of a polyester material by solid-state polymerization, wherein the polyester material is heat-treated in a heat treatment container (6), the polyester material being introduced into a preheating container (2) prior to being conveyed into the heat treatment container (6), in which preheating container it is heated to a heat treatment temperature of the heat treatment container (6) or to a temperature above that and is delivered to the heat treatment container (6) after having reached said temperature. The preheating container (2) is small in comparison with the heat treatment container (6) so that the relatively small amount of polyester material contained therein can quickly be heated to the intended temperature, thereby leading to a short residence time in the preheating container.Type: GrantFiled: September 25, 2003Date of Patent: April 15, 2008Assignee: Starlinger & Co Gesellschaft m.b.H.Inventors: Markus Fellinger, Christian Lovranich

Patent number: 7077344Abstract: A device for compacting loosely packed materials, in particular synthetic materials, comprises a shredder/conveyor rotor body arranged in a casing and drivable with the rotation around an axis of rotation and a consecutively arranged extruder with an extruder screw that is arranged rotatably and coaxially to the shredder/conveyor rotor body. Materials supplied to the shredder/conveyor rotor body are conveyed to the extruder screw, whereby they optionally are shredded. According to the invention, the shredder/conveyor rotor body is configured as a hollow body open at the front side opposite the extruder and has at least one rotary bearing in its interior, which rotary bearing rests on an abutment body projecting from the open front side into the interior of the shredder/conveyor rotor body.Type: GrantFiled: September 10, 2004Date of Patent: July 18, 2006Assignee: Starlinger & Co.

Publication number: 20060034961Abstract: A device for the processing of plastic waste, comprising a shredding device (9) arranged in a casing (1) and rotatable around an axis of rotation (2), which shredding device carries a plurality of knives (3) at its periphery, and an extruder comprising an extruder screw (4), with the casing (1) comprising a feed opening (5) for the supply of plastic waste to the shredding device (9) and a discharge opening (6) for the delivery of shredded plastic waste to the extruder. The shredding device (9) and its knives (3), respectively, can be moved past the extruder screw (4) at such a small distance (h) that effective shear gaps are formed between the knives (3) of the shredding device (9) and a helix (4a) of the extruder screw (4).Type: ApplicationFiled: March 11, 2003Publication date: February 16, 2006Applicant: Starlinger & Co.

Patent number: 6877685Abstract: The invention relates to a processing device for, especially thermoplastic, synthetic material. The inventive device consists of a disintegration device and/or a conveying device having an upstream disintegration device and of a directly connected extruding device. The disintegrating/conveying device consists of a knife-carrying processor drum/conveyor worm (3/9) or a combination thereof. Said drum/worm circulates in a conveyor pipe/worm trough (6/38) in a driven manner. Said pipe/worm is provided with a supply opening (11) directed towards the top and an outlet (10). The processing drum (3) or the conveyor worm (9) and the extruder worm (8) are aligned with the longitudinal axes (17, 20) and the processing drum/conveyor worm (3, 9) is detachably and mechanically connected to the extruder worm (8) and both are driven by a transmission (31) and a driving motor (34).Type: GrantFiled: June 27, 2002Date of Patent: April 12, 2005Inventors: Gerold Barth, Manfred Dobersberger, Markus Fellinger, Günter Kroiss
