Patent number: 8631925Abstract: A roll stand assembly for processing a sheet product and having a frame and a plurality of rolls operatively position on the frame so as to define a plurality of nip locations between cooperating pairs of the rolls. The roll axes are substantially parallel with the plurality of rolls operatively positioned on the frame. Two of the rolls are relatively repositionable by guided relative movement therebetween along a first path to vary a gap between the two rolls. The two rolls are relatively repositionable by guided relative movement therebetween along a second path that is different than the first path to vary the gap between the two rolls. A control system is provided through which the two rolls are relatively repositioned by causing guided relative movement between the two rolls in the first and second paths.Type: GrantFiled: September 12, 2012Date of Patent: January 21, 2014Assignee: Processing Technologies, LLCInventors: Dana R.

Patent number: 8342118Abstract: An apparatus for extrusion forming a sheet product having an extruder assembly with a sheet die through which a flowable material is delivered and a roll stand assembly made up of a roll stack sub-assembly and a sheet take-off sub-assembly. The roll stack assembly has first and second rolls between which a nip location is defined at which flowable material from the sheet die is delivered. The sheet take-off sub-assembly produces an advancing force upon a first sheet component made up of at least the first sheet layer. The roll stand assembly further has a coating system for applying a coating component to a surface on at least one sheet component advancing through the apparatus. The roll stand assembly is constructed to be reconfigured thereby to change a path traveled by the at least one sheet component and facilitate selective application of the coating component.Type: GrantFiled: June 1, 2009Date of Patent: January 1, 2013Assignee: Processing Technologies, LLCInventors: Dana R.

Patent number: 8240180Abstract: An apparatus for continuously forming an extruded sheet product having an extruder assembly with a sheet die for delivering flowable material. A roll stand assembly has a main frame with first and second rolls. A vertical height positioning mechanism is operated to vary the relationship between the sheet die and nip location between rolls and has first and second lift components that cooperate with the main frame at first and second laterally spaced locations. The first and second lift components are each movable in first and second opposite paths to selectively elevate and lower the nip location relative to the sheet die. The vertical height positioning mechanism further has an actuating system to selectively and simultaneously cause the first and second lift components to move.Type: GrantFiled: June 1, 2009Date of Patent: August 14, 2012Assignee: Processing Technologies, LLCInventors: Dana R.
