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.

Compacting screed extension for paving

Sven N. Hedin
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.

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.
