TLDR
In this paper, a paving screed comprises a base screed and extension screed, each of which is support via an extension guiding structure at a guidance fixed in the base sreed such that each extension sreed can be extended and retracted.Abstract:
A paving screed comprises a base screed and extension screeds each of which is support via an extension guiding structure at a guidance fixed in the base screed such that each extension screed can be extended and retracted. A multiple point suspension is provided between the extension guiding structure and the guidance. A frame carrying the sole plate of the extension screed A is arranged below the extension guiding structure. Substantially vertical adjustment assemblies make it possible to adjust the height position of the frame via drives. A lateral inclination adjustment assembly is provided structurally separated from the adjustment assemblies either for the frame or within the frame for the sole plate of the extension screed.read more

Paving machine control and method
TL;DR: In this paper, the vertical height of the tow point is controlled by an hydraulic cylinder on a machine in response to a valve control signal applied to an hydraulic valve by a valve controller drive.
Patent
Paving machine with a storage container
TL;DR: In this article, a self-propelled paving machine for floor coverings respectively cover layers and resilient base layers is described, where the material is distributed uniformly over a fill-in width on a prepared under-floor, and a storage container is provided which is connected with the fill-up area of the paving machine.

Patent
Compacting screed extension for paving
TL;DR: In this paper, a paving screed extension is selectively connected to opposing sides of a paving-screed used to lay a blacktop over large surfaces to create a wedge notch joint for merging with an adjacent swath of blacktop.
Patent
Extendable Screed Height Adjusting System with Angle of Attack Adjustment
TL;DR: In this article, an extendable screed has independent height and angle of attack adjustment for a lower extender frame, where at least one post and cylinder assembly are used to couple the lower-extender frame to an upper-extended frame at a pin that allows rotation of the lower extenders relative to the upper extenders, and a vertical adjuster uses a drive rod with a pivoting attachment at the lowerextenders.

Apparatus and method for three-dimensional contouring
TL;DR: In this article, a contouring assembly with a pair of fluid cylinders is used to create a three-dimensional curved surface as it passes over an area to be contoured, which is then tracked by a second tracking device to determine the 3D position of the second end.
Patent
Asphalt paver with telescoping screed
TL;DR: In this article, a floating screed type asphalt paver with extendable, retractable auxiliary screed units which, in their retracted positions, are mounted in front of the main screed and carry edger plates is described.

Screed control system for an asphalt paver and method of use
TL;DR: In this paper, a control system for a floating screed assembly for an asphalt paving machine is described, which consists of a main screed and an extension screed unit, and a controller receives position signals and produces command signals to control the extending, retracting, and pivoting of the extension unit to a desired position.
Patent
Extension screed for a paving vehicle
TL;DR: An extension screed is a paving vehicle screed assembly that includes two base members movably connectable with the main screed and two vertical actuators each extending between the main and a separate base member as mentioned in this paper.
