Publication number: 20120313274Abstract: A method of controlling a slot die comprises, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, changing the position of the actuators with the controller to either increase the cross-directional thickness of the fluid flow path adjacent each of the actuators or substantially close the fluid flow path adjacent the actuators, and after changing the cross-directional thickness of the fluid flow path adjacent each of the actuators, while continuing to pass the extrudate through the fluid flow path and out the applicator slot, repositioning each of the actuators with the controller according to the set of discrete settings to resume operating the slot die with the actuators positioned according to the set of discrete settings.Type: ApplicationFiled: June 7, 2011Publication date: December 13, 2012Inventors: Pentti K.

Publication number: 20100168894Abstract: In one embodiment, a computer implemented system and method for selecting dimensions of a die is disclosed. The method may include prompting a user to select a coating uniformity required to produce a particular coated product with the die. The user may also be prompted to select a slot height of the die. In some embodiments, the user may specify a value for one or more dimensions of the die. The method may then determine the total indicated run-out (TIR) of the coated product as a function of the dimensions of the die not having a user specified value. In certain embodiments, the method provides a thermal treatment process for reducing the number of finishing (e.g., grinding) cycles needed to produce a desired die flatness. In another embodiment, a computer implemented method for designing a coating die to achieve a desired coating uniformity with a particular coating fluid having a specified rheological characteristic is disclosed.Type: ApplicationFiled: June 25, 2007Publication date: July 1, 2010Inventors: Robert A. Yapel, Robert B. Secor', Michael J. Tichy, Bruce D. Shalles, Charles N. DeVore, Jennifer L. Trice, James M. Nelson, Andrzej P. Jaworski, William R. Dudley, Keith R. Bruesewitz

Patent number: 7615175Abstract: The invention is a method of forming extrudate having substantially uniform thickness. A shim is formed which has a thickness variation of less than or equal to about 0.5 mil (13 microns) total indicated runout. This shim is disposed between a first die portion having a first surface and a second die portion having a second surface. A slot is formed between the first surface and the second surface. The slot has a height dimension substantially the same as the shim thickness. Flowable material is extruded through the slot.Type: GrantFiled: August 3, 2004Date of Patent: November 10, 2009Assignee: 3M Innovative Properties CompanyInventors: James M. Nelson, Raghunath Padiyath, Robert B. Secor, Mark J. Stevenson, Michael J. Tichy, Robert A. Yapel

Patent number: 7455897Abstract: The invention is a contact die for dispensing of flowable material on a substrate. The contact die includes at least one die block including a first internal passage. A die lip portion is disposed on the die block having a lateral dimension. A first plurality of orifices is disposed through the die lip portion proximate to each other and in communication with the internal passage to dispense flowable material as a single strip on the substrate. A first edge is disposed on one lateral side of the first plurality of orifices to direct the flowable material.Type: GrantFiled: September 3, 2004Date of Patent: November 25, 2008Assignee: 3M Innovative Properties CompanyInventors: Pentti K.

Patent number: 5612092Abstract: To knife-coat elastic liquids without the presence of flow instability, the extension rate in the upstream region of the coating bead is kept low by increasing the distance over which the liquid must accelerate. The onset of the flow instability is delayed by insuring that the upstream liquid-air interface of the coating bead is relatively long and flat. This is accomplished by allowing the elastic liquid to pull itself over a relatively large distance out of a trough and into the knifing passage. The liquid is able to ascend into the knifing passage by virtue of liquid tension developed by the extensional flow in the upstream region of the coating bead.Type: GrantFiled: October 6, 1994Date of Patent: March 18, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Mark R. Strenger, Robert B. Secor, Bernhard Lenz
